+What:		/sys/kernel/debug/ec/*/{gpe,use_global_lock,io}
+Date:		July 2010
+Contact:	Thomas Renninger <trenn@suse.de>
+Description:
+
+General information like which GPE is assigned to the EC and whether
+the global lock should get used.
+Knowing the EC GPE one can watch the amount of HW events related to
+the EC here (XY -> GPE number from /sys/kernel/debug/ec/*/gpe):
+/sys/firmware/acpi/interrupts/gpeXY
+
+The io file is binary and a userspace tool located here:
+ftp://ftp.suse.com/pub/people/trenn/sources/ec/
+should get used to read out the 256 Embedded Controller registers
+or writing to them.
+
+CAUTION: Do not write to the Embedded Controller if you don't know
+what you are doing! Rebooting afterwards also is a good idea.
+This can influence the way your machine is cooled and fans may
+not get switched on again after you did a wrong write.

-What:		/sys/kernel/debug/kmemtrace/
-Date:		July 2008
-Contact:	Eduard - Gabriel Munteanu <eduard.munteanu@linux360.ro>
-Description:
-
-In kmemtrace-enabled kernels, the following files are created:
-
-/sys/kernel/debug/kmemtrace/
-	cpu<n>		(0400)	Per-CPU tracing data, see below. (binary)
-	total_overruns	(0400)	Total number of bytes which were dropped from
-				cpu<n> files because of full buffer condition,
-				non-binary. (text)
-	abi_version	(0400)	Kernel's kmemtrace ABI version. (text)
-
-Each per-CPU file should be read according to the relay interface. That is,
-the reader should set affinity to that specific CPU and, as currently done by
-the userspace application (though there are other methods), use poll() with
-an infinite timeout before every read(). Otherwise, erroneous data may be
-read. The binary data has the following _core_ format:
-
-	Event ID	(1 byte)	Unsigned integer, one of:
-		0 - represents an allocation (KMEMTRACE_EVENT_ALLOC)
-		1 - represents a freeing of previously allocated memory
-		    (KMEMTRACE_EVENT_FREE)
-	Type ID		(1 byte)	Unsigned integer, one of:
-		0 - this is a kmalloc() / kfree()
-		1 - this is a kmem_cache_alloc() / kmem_cache_free()
-		2 - this is a __get_free_pages() et al.
-	Event size	(2 bytes)	Unsigned integer representing the
-					size of this event. Used to extend
-					kmemtrace. Discard the bytes you
-					don't know about.
-	Sequence number	(4 bytes)	Signed integer used to reorder data
-					logged on SMP machines. Wraparound
-					must be taken into account, although
-					it is unlikely.
-	Caller address	(8 bytes)	Return address to the caller.
-	Pointer to mem	(8 bytes)	Pointer to target memory area. Can be
-					NULL, but not all such calls might be
-					recorded.
-
-In case of KMEMTRACE_EVENT_ALLOC events, the next fields follow:
-
-	Requested bytes	(8 bytes)	Total number of requested bytes,
-					unsigned, must not be zero.
-	Allocated bytes (8 bytes)	Total number of actually allocated
-					bytes, unsigned, must not be lower
-					than requested bytes.
-	Requested flags	(4 bytes)	GFP flags supplied by the caller.
-	Target CPU	(4 bytes)	Signed integer, valid for event id 1.
-					If equal to -1, target CPU is the same
-					as origin CPU, but the reverse might
-					not be true.
-
-The data is made available in the same endianness the machine has.
-
-Other event ids and type ids may be defined and added. Other fields may be
-added by increasing event size, but see below for details.
-Every modification to the ABI, including new id definitions, are followed
-by bumping the ABI version by one.
-
-Adding new data to the packet (features) is done at the end of the mandatory
-data:
-	Feature size	(2 byte)
-	Feature ID	(1 byte)
-	Feature data	(Feature size - 3 bytes)

+<para>The LIRC device interface is a bi-directional interface for
+transporting raw IR data between userspace and kernelspace. Fundamentally,
+it is just a chardev (/dev/lircX, for X = 0, 1, 2, ...), with a number
+of standard struct file_operations defined on it. With respect to
+transporting raw IR data to and fro, the essential fops are read, write
+and ioctl.</para>

+<title>LIRC read fop</title>
+
+<para>The lircd userspace daemon reads raw IR data from the LIRC chardev. The
+exact format of the data depends on what modes a driver supports, and what
+mode has been selected. lircd obtains supported modes and sets the active mode
+via the ioctl interface, detailed at <xref linkend="lirc_ioctl"/>. The generally
+preferred mode is LIRC_MODE_MODE2, in which packets containing an int value
+describing an IR signal are read from the chardev.</para>

+<title>LIRC write fop</title>
+
+<para>The data written to the chardev is a pulse/space sequence of integer
+values. Pulses and spaces are only marked implicitly by their position. The
+data must start and end with a pulse, therefore, the data must always include
+an unevent number of samples. The write function must block until the data has
+been transmitted by the hardware.</para>

+<section id="lirc_ioctl">
+<title>LIRC ioctl fop</title>
+
+<para>The LIRC device's ioctl definition is bound by the ioctl function
+definition of struct file_operations, leaving us with an unsigned int
+for the ioctl command and an unsigned long for the arg. For the purposes
+of ioctl portability across 32-bit and 64-bit, these values are capped
+to their 32-bit sizes.</para>
+
+<para>The following ioctls can be used to change specific hardware settings.
+In general each driver should have a default set of settings. The driver
+implementation is expected to re-apply the default settings when the device
+is closed by user-space, so that every application opening the device can rely
+on working with the default settings initially.</para>

+--- What is AppArmor? ---
+
+AppArmor is MAC style security extension for the Linux kernel.  It implements
+a task centered policy, with task "profiles" being created and loaded
+from user space.  Tasks on the system that do not have a profile defined for
+them run in an unconfined state which is equivalent to standard Linux DAC
+permissions.
+
+--- How to enable/disable ---
+
+set CONFIG_SECURITY_APPARMOR=y
+
+If AppArmor should be selected as the default security module then
+   set CONFIG_DEFAULT_SECURITY="apparmor"
+   and CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1
+
+Build the kernel
+
+If AppArmor is not the default security module it can be enabled by passing
+security=apparmor on the kernel's command line.
+
+If AppArmor is the default security module it can be disabled by passing
+apparmor=0, security=XXXX (where XXX is valid security module), on the
+kernel's command line
+
+For AppArmor to enforce any restrictions beyond standard Linux DAC permissions
+policy must be loaded into the kernel from user space (see the Documentation
+and tools links).

+
+ Getting Coccinelle
+~~~~~~~~~~~~~~~~~~~~
+
+The semantic patches included in the kernel use the 'virtual rule'
+feature which was introduced in Coccinelle version 0.1.11.
+
+Coccinelle (>=0.2.0) is available through the package manager
+of many distributions, e.g. :
+
+ - Debian (>=squeeze)
+ - Fedora (>=13)
+ - Ubuntu (>=10.04 Lucid Lynx)
+ - OpenSUSE
+ - Arch Linux
+ - NetBSD
+ - FreeBSD
+
+
+You can get the latest version released from the Coccinelle homepage at
+http://coccinelle.lip6.fr/
+
+Once you have it, run the following command:
+
+     	./configure
+        make
+
+as a regular user, and install it with
+
+        sudo make install
+
+
+ Using Coccinelle on the Linux kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A Coccinelle-specific target is defined in the top level
+Makefile. This target is named 'coccicheck' and calls the 'coccicheck'
+front-end in the 'scripts' directory.
+
+Four modes are defined: report, patch, context, and org. The mode to
+use is specified by setting the MODE variable with 'MODE=<mode>'.
+
+'report' generates a list in the following format:
+  file:line:column-column: message
+
+'patch' proposes a fix, when possible.
+
+'context' highlights lines of interest and their context in a
+diff-like style.Lines of interest are indicated with '-'.
+
+'org' generates a report in the Org mode format of Emacs.
+
+Note that not all semantic patches implement all modes.
+
+To make a report for every semantic patch, run the following command:
+
+	make coccicheck MODE=report
+
+NB: The 'report' mode is the default one.
+
+To produce patches, run:
+
+	make coccicheck MODE=patch
+
+
+The coccicheck target applies every semantic patch available in the
+subdirectories of 'scripts/coccinelle' to the entire Linux kernel.
+
+For each semantic patch, a changelog message is proposed.  It gives a
+description of the problem being checked by the semantic patch, and
+includes a reference to Coccinelle.
+
+As any static code analyzer, Coccinelle produces false
+positives. Thus, reports must be carefully checked, and patches
+reviewed.
+
+
+ Using Coccinelle with a single semantic patch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The optional make variable COCCI can be used to check a single
+semantic patch. In that case, the variable must be initialized with
+the name of the semantic patch to apply.
+
+For instance:
+
+	make coccicheck COCCI=<my_SP.cocci> MODE=patch
+or
+	make coccicheck COCCI=<my_SP.cocci> MODE=report
+
+
+ Proposing new semantic patches
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New semantic patches can be proposed and submitted by kernel
+developers. For sake of clarity, they should be organized in the
+subdirectories of 'scripts/coccinelle/'.
+
+
+ Detailed description of the 'report' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+'report' generates a list in the following format:
+  file:line:column-column: message
+
+Example:
+
+Running
+
+	make coccicheck MODE=report COCCI=scripts/coccinelle/err_cast.cocci
+
+will execute the following part of the SmPL script.
+
+<smpl>

+
+
+ Detailed description of the 'patch' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When the 'patch' mode is available, it proposes a fix for each problem
+identified.
+
+Example:
+
+Running
+	make coccicheck MODE=patch COCCI=scripts/coccinelle/err_cast.cocci
+

+Description
+-----------
+
+This driver permits reading package level temperature sensor embedded inside
+Intel CPU package. The sensors can be in core, uncore, memory controller, or
+other components in a package. The feature is first implemented in Intel Sandy
+Bridge platform.
+
+Temperature is measured in degrees Celsius and measurement resolution is
+1 degree C. Valid temperatures are from 0 to TjMax degrees C, because the actual
+value of temperature register is in fact a delta from TjMax.
+
+Temperature known as TjMax is the maximum junction temperature of package.
+We get this from MSR_IA32_TEMPERATURE_TARGET. If the MSR is not accessible,
+we define TjMax as 100 degrees Celsius. At this temperature, protection
+mechanism will perform actions to forcibly cool down the package. Alarm
+may be raised, if the temperature grows enough (more than TjMax) to trigger
+the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
+
+temp1_input	  - Package temperature (in millidegrees Celsius).
+temp1_max        - All cooling devices should be turned on.
+temp1_crit	  - Maximum junction temperature (in millidegrees Celsius).
+temp1_crit_alarm - Set when Out-of-spec bit is set, never clears.
+		    Correct CPU operation is no longer guaranteed.

 Introduction
 ------------

-report details for an arbitrary number of fingers.
+In order to utilize the full power of the new multi-touch and multi-user
+devices, a way to report detailed data from multiple contacts, i.e.,
+objects in direct contact with the device surface, is needed.  This
+document describes the multi-touch (MT) protocol which allows kernel
+drivers to report details for an arbitrary number of contacts.
+
+The protocol is divided into two types, depending on the capabilities of the
+hardware. For devices handling anonymous contacts (type A), the protocol
+describes how to send the raw data for all contacts to the receiver. For
+devices capable of tracking identifiable contacts (type B), the protocol
+describes how to send updates for individual contacts via event slots.
+
+
+Protocol Usage
+--------------
+
+Contact details are sent sequentially as separate packets of ABS_MT
+events. Only the ABS_MT events are recognized as part of a contact
+packet. Since these events are ignored by current single-touch (ST)
+applications, the MT protocol can be implemented on top of the ST protocol
+in an existing driver.
+
+Drivers for type A devices separate contact packets by calling
+input_mt_sync() at the end of each packet. This generates a SYN_MT_REPORT
+event, which instructs the receiver to accept the data for the current
+contact and prepare to receive another.
+
+Drivers for type B devices separate contact packets by calling
+input_mt_slot(), with a slot as argument, at the beginning of each packet.
+This generates an ABS_MT_SLOT event, which instructs the receiver to
+prepare for updates of the given slot.
+
+All drivers mark the end of a multi-touch transfer by calling the usual
+input_sync() function. This instructs the receiver to act upon events
+accumulated since last EV_SYN/SYN_REPORT and prepare to receive a new set
+of events/packets.
+
+The main difference between the stateless type A protocol and the stateful
+type B slot protocol lies in the usage of identifiable contacts to reduce
+the amount of data sent to userspace. The slot protocol requires the use of
+the ABS_MT_TRACKING_ID, either provided by the hardware or computed from
+the raw data [5].
+
+For type A devices, the kernel driver should generate an arbitrary
+enumeration of the full set of anonymous contacts currently on the
+surface. The order in which the packets appear in the event stream is not
+important.  Event filtering and finger tracking is left to user space [3].
+
+For type B devices, the kernel driver should associate a slot with each
+identified contact, and use that slot to propagate changes for the contact.
+Creation, replacement and destruction of contacts is achieved by modifying
+the ABS_MT_TRACKING_ID of the associated slot.  A non-negative tracking id
+is interpreted as a contact, and the value -1 denotes an unused slot.  A
+tracking id not previously present is considered new, and a tracking id no
+longer present is considered removed.  Since only changes are propagated,
+the full state of each initiated contact has to reside in the receiving
+end.  Upon receiving an MT event, one simply updates the appropriate
+attribute of the current slot.
+
+
+Protocol Example A
+------------------
+
+Here is what a minimal event sequence for a two-contact touch would look
+like for a type A device:
+
+   ABS_MT_POSITION_X x[0]
+   ABS_MT_POSITION_Y y[0]
+   SYN_MT_REPORT
+   ABS_MT_POSITION_X x[1]
+   ABS_MT_POSITION_Y y[1]
+   SYN_MT_REPORT
+   SYN_REPORT
 
+The sequence after moving one of the contacts looks exactly the same; the
+raw data for all present contacts are sent between every synchronization
+with SYN_REPORT.
 
-Usage
------
+Here is the sequence after lifting the first contact:
+
+   ABS_MT_POSITION_X x[1]
+   ABS_MT_POSITION_Y y[1]
+   SYN_MT_REPORT
+   SYN_REPORT
+
+And here is the sequence after lifting the second contact:
+
+   SYN_MT_REPORT
+   SYN_REPORT
+
+If the driver reports one of BTN_TOUCH or ABS_PRESSURE in addition to the
+ABS_MT events, the last SYN_MT_REPORT event may be omitted. Otherwise, the
+last SYN_REPORT will be dropped by the input core, resulting in no
+zero-contact event reaching userland.
 
-Anonymous finger details are sent sequentially as separate packets of ABS

+   ABS_MT_TRACKING_ID 46
+   ABS_MT_POSITION_X x[1]
+   ABS_MT_POSITION_Y y[1]
+   SYN_REPORT
+
+Here is the sequence after moving contact 45 in the x direction:
+
+   ABS_MT_SLOT 0
+   ABS_MT_POSITION_X x[0]
+   SYN_REPORT
+
+Here is the sequence after lifting the contact in slot 0:
+
+   ABS_MT_TRACKING_ID -1
+   SYN_REPORT
+
+The slot being modified is already 0, so the ABS_MT_SLOT is omitted.  The
+message removes the association of slot 0 with contact 45, thereby
+destroying contact 45 and freeing slot 0 to be reused for another contact.
+
+Finally, here is the sequence after lifting the second contact:

+This ioctl returns x86 cpuid features which are supported by both the hardware
+and kvm.  Userspace can use the information returned by this ioctl to
+construct cpuid information (for KVM_SET_CPUID2) that is consistent with
+hardware, kernel, and userspace capabilities, and with user requirements (for
+example, the user may wish to constrain cpuid to emulate older hardware,
+or for feature consistency across a cluster).
+
+Userspace invokes KVM_GET_SUPPORTED_CPUID by passing a kvm_cpuid2 structure
+with the 'nent' field indicating the number of entries in the variable-size
+array 'entries'.  If the number of entries is too low to describe the cpu
+capabilities, an error (E2BIG) is returned.  If the number is too high,
+the 'nent' field is adjusted and an error (ENOMEM) is returned.  If the
+number is just right, the 'nent' field is adjusted to the number of valid
+entries in the 'entries' array, which is then filled.
+
+The entries returned are the host cpuid as returned by the cpuid instruction,
+with unknown or unsupported features masked out.  The fields in each entry
+are defined as follows:
+
+  function: the eax value used to obtain the entry
+  index: the ecx value used to obtain the entry (for entries that are
+         affected by ecx)
+  flags: an OR of zero or more of the following:
+        KVM_CPUID_FLAG_SIGNIFCANT_INDEX:
+           if the index field is valid
+        KVM_CPUID_FLAG_STATEFUL_FUNC:
+           if cpuid for this function returns different values for successive
+           invocations; there will be several entries with the same function,
+           all with this flag set
+        KVM_CPUID_FLAG_STATE_READ_NEXT:
+           for KVM_CPUID_FLAG_STATEFUL_FUNC entries, set if this entry is
+           the first entry to be read by a cpu
+   eax, ebx, ecx, edx: the values returned by the cpuid instruction for
+         this function/index combination

+Emulating cr0.wp
+================
+
+If tdp is not enabled, the host must keep cr0.wp=1 so page write protection
+works for the guest kernel, not guest guest userspace.  When the guest
+cr0.wp=1, this does not present a problem.  However when the guest cr0.wp=0,
+we cannot map the permissions for gpte.u=1, gpte.w=0 to any spte (the
+semantics require allowing any guest kernel access plus user read access).
+
+We handle this by mapping the permissions to two possible sptes, depending
+on fault type:
+
+- kernel write fault: spte.u=0, spte.w=1 (allows full kernel access,
+  disallows user access)
+- read fault: spte.u=1, spte.w=0 (allows full read access, disallows kernel
+  write access)
+
+(user write faults generate a #PF)
+
+Large pages
+===========
+
+The mmu supports all combinations of large and small guest and host pages.
+Supported page sizes include 4k, 2M, 4M, and 1G.  4M pages are treated as
+two separate 2M pages, on both guest and host, since the mmu always uses PAE
+paging.
+
+To instantiate a large spte, four constraints must be satisfied:
+
+- the spte must point to a large host page
+- the guest pte must be a large pte of at least equivalent size (if tdp is
+  enabled, there is no guest pte and this condition is satisified)
+- if the spte will be writeable, the large page frame may not overlap any
+  write-protected pages
+- the guest page must be wholly contained by a single memory slot
+
+To check the last two conditions, the mmu maintains a ->write_count set of
+arrays for each memory slot and large page size.  Every write protected page
+causes its write_count to be incremented, thus preventing instantiation of
+a large spte.  The frames at the end of an unaligned memory slot have
+artificically inflated ->write_counts so they can never be instantiated.

+KVM-specific MSRs.
+Glauber Costa <glommer@redhat.com>, Red Hat Inc, 2010
+=====================================================
+
+KVM makes use of some custom MSRs to service some requests.
+At present, this facility is only used by kvmclock.
+
+Custom MSRs have a range reserved for them, that goes from
+0x4b564d00 to 0x4b564dff. There are MSRs outside this area,
+but they are deprecated and their use is discouraged.
+
+Custom MSR list
+--------
+
+The current supported Custom MSR list is:
+
+MSR_KVM_WALL_CLOCK_NEW:   0x4b564d00
+
+	data: 4-byte alignment physical address of a memory area which must be
+	in guest RAM. This memory is expected to hold a copy of the following
+	structure:
+
+	struct pvclock_wall_clock {
+		u32   version;
+		u32   sec;
+		u32   nsec;
+	} __attribute__((__packed__));
+
+	whose data will be filled in by the hypervisor. The hypervisor is only
+	guaranteed to update this data at the moment of MSR write.
+	Users that want to reliably query this information more than once have
+	to write more than once to this MSR. Fields have the following meanings:
+
+		version: guest has to check version before and after grabbing
+		time information and check that they are both equal and even.
+		An odd version indicates an in-progress update.
+
+		sec: number of seconds for wallclock.
+
+		nsec: number of nanoseconds for wallclock.
+
+	Note that although MSRs are per-CPU entities, the effect of this
+	particular MSR is global.
+
+	Availability of this MSR must be checked via bit 3 in 0x4000001 cpuid
+	leaf prior to usage.
+
+MSR_KVM_SYSTEM_TIME_NEW:  0x4b564d01
+
+	data: 4-byte aligned physical address of a memory area which must be in
+	guest RAM, plus an enable bit in bit 0. This memory is expected to hold
+	a copy of the following structure:
+
+	struct pvclock_vcpu_time_info {
+		u32   version;
+		u32   pad0;
+		u64   tsc_timestamp;
+		u64   system_time;
+		u32   tsc_to_system_mul;
+		s8    tsc_shift;
+		u8    flags;
+		u8    pad[2];
+	} __attribute__((__packed__)); /* 32 bytes */
+
+	whose data will be filled in by the hypervisor periodically. Only one
+	write, or registration, is needed for each VCPU. The interval between
+	updates of this structure is arbitrary and implementation-dependent.
+	The hypervisor may update this structure at any time it sees fit until
+	anything with bit0 == 0 is written to it.
+
+	Fields have the following meanings:
+
+		version: guest has to check version before and after grabbing
+		time information and check that they are both equal and even.
+		An odd version indicates an in-progress update.
+
+		tsc_timestamp: the tsc value at the current VCPU at the time
+		of the update of this structure. Guests can subtract this value
+		from current tsc to derive a notion of elapsed time since the
+		structure update.
+
+		system_time: a host notion of monotonic time, including sleep
+		time at the time this structure was last updated. Unit is
+		nanoseconds.
+
+		tsc_to_system_mul: a function of the tsc frequency. One has
+		to multiply any tsc-related quantity by this value to get
+		a value in nanoseconds, besides dividing by 2^tsc_shift
+
+		tsc_shift: cycle to nanosecond divider, as a power of two, to
+		allow for shift rights. One has to shift right any tsc-related
+		quantity by this value to get a value in nanoseconds, besides
+		multiplying by tsc_to_system_mul.
+
+		With this information, guests can derive per-CPU time by
+		doing:
+
+			time = (current_tsc - tsc_timestamp)
+			time = (time * tsc_to_system_mul) >> tsc_shift
+			time = time + system_time
+
+		flags: bits in this field indicate extended capabilities
+		coordinated between the guest and the hypervisor. Availability
+		of specific flags has to be checked in 0x40000001 cpuid leaf.
+		Current flags are:
+
+		 flag bit   | cpuid bit    | meaning
+		-------------------------------------------------------------
+			    |	           | time measures taken across
+		     0      |	   24      | multiple cpus are guaranteed to
+			    |		   | be monotonic
+		-------------------------------------------------------------
+
+	Availability of this MSR must be checked via bit 3 in 0x4000001 cpuid
+	leaf prior to usage.
+
+
+MSR_KVM_WALL_CLOCK:  0x11
+
+	data and functioning: same as MSR_KVM_WALL_CLOCK_NEW. Use that instead.
+
+	This MSR falls outside the reserved KVM range and may be removed in the
+	future. Its usage is deprecated.
+
+	Availability of this MSR must be checked via bit 0 in 0x4000001 cpuid
+	leaf prior to usage.
+
+MSR_KVM_SYSTEM_TIME: 0x12
+
+	data and functioning: same as MSR_KVM_SYSTEM_TIME_NEW. Use that instead.
+
+	This MSR falls outside the reserved KVM range and may be removed in the
+	future. Its usage is deprecated.
+
+	Availability of this MSR must be checked via bit 0 in 0x4000001 cpuid
+	leaf prior to usage.
+
+	The suggested algorithm for detecting kvmclock presence is then:
+
+		if (!kvm_para_available())    /* refer to cpuid.txt */
+			return NON_PRESENT;
+
+		flags = cpuid_eax(0x40000001);
+		if (flags & 3) {
+			msr_kvm_system_time = MSR_KVM_SYSTEM_TIME_NEW;
+			msr_kvm_wall_clock = MSR_KVM_WALL_CLOCK_NEW;
+			return PRESENT;
+		} else if (flags & 0) {
+			msr_kvm_system_time = MSR_KVM_SYSTEM_TIME;
+			msr_kvm_wall_clock = MSR_KVM_WALL_CLOCK;
+			return PRESENT;
+		} else
+			return NON_PRESENT;

+Review checklist for kvm patches
+================================
+
+1.  The patch must follow Documentation/CodingStyle and
+    Documentation/SubmittingPatches.
+
+2.  Patches should be against kvm.git master branch.
+
+3.  If the patch introduces or modifies a new userspace API:
+    - the API must be documented in Documentation/kvm/api.txt
+    - the API must be discoverable using KVM_CHECK_EXTENSION
+
+4.  New state must include support for save/restore.
+
+5.  New features must default to off (userspace should explicitly request them).
+    Performance improvements can and should default to on.
+
+6.  New cpu features should be exposed via KVM_GET_SUPPORTED_CPUID2
+
+7.  Emulator changes should be accompanied by unit tests for qemu-kvm.git
+    kvm/test directory.
+
+8.  Changes should be vendor neutral when possible.  Changes to common code
+    are better than duplicating changes to vendor code.
+
+9.  Similarly, prefer changes to arch independent code than to arch dependent
+    code.
+
+10. User/kernel interfaces and guest/host interfaces must be 64-bit clean
+    (all variables and sizes naturally aligned on 64-bit; use specific types
+    only - u64 rather than ulong).
+
+11. New guest visible features must either be documented in a hardware manual
+    or be accompanied by documentation.
+
+12. Features must be robust against reset and kexec - for example, shared
+    host/guest memory must be unshared to prevent the host from writing to
+    guest memory that the guest has not reserved for this purpose.

-4. Querying Bonding Configuration 
+3.5 Overriding Configuration for Special Cases
+----------------------------------------------
+When using the bonding driver, the physical port which transmits a frame is
+typically selected by the bonding driver, and is not relevant to the user or
+system administrator.  The output port is simply selected using the policies of
+the selected bonding mode.  On occasion however, it is helpful to direct certain
+classes of traffic to certain physical interfaces on output to implement
+slightly more complex policies.  For example, to reach a web server over a
+bonded interface in which eth0 connects to a private network, while eth1
+connects via a public network, it may be desirous to bias the bond to send said
+traffic over eth0 first, using eth1 only as a fall back, while all other traffic
+can safely be sent over either interface.  Such configurations may be achieved
+using the traffic control utilities inherent in linux.
+
+By default the bonding driver is multiqueue aware and 16 queues are created
+when the driver initializes (see Documentation/networking/multiqueue.txt
+for details).  If more or less queues are desired the module parameter
+tx_queues can be used to change this value.  There is no sysfs parameter
+available as the allocation is done at module init time.
+
+The output of the file /proc/net/bonding/bondX has changed so the output Queue
+ID is now printed for each slave:
+
+Bonding Mode: fault-tolerance (active-backup)
+Primary Slave: None
+Currently Active Slave: eth0
+MII Status: up
+MII Polling Interval (ms): 0
+Up Delay (ms): 0
+Down Delay (ms): 0
+
+Slave Interface: eth0
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cb
+Slave queue ID: 0
+
+Slave Interface: eth1
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cc
+Slave queue ID: 2
+
+The queue_id for a slave can be set using the command:
+
+# echo "eth1:2" > /sys/class/net/bond0/bonding/queue_id
+
+Any interface that needs a queue_id set should set it with multiple calls
+like the one above until proper priorities are set for all interfaces.  On
+distributions that allow configuration via initscripts, multiple 'queue_id'
+arguments can be added to BONDING_OPTS to set all needed slave queues.
+
+These queue id's can be used in conjunction with the tc utility to configure
+a multiqueue qdisc and filters to bias certain traffic to transmit on certain
+slave devices.  For instance, say we wanted, in the above configuration to
+force all traffic bound to 192.168.1.100 to use eth1 in the bond as its output
+device. The following commands would accomplish this:
+
+# tc qdisc add dev bond0 handle 1 root multiq
+
+# tc filter add dev bond0 protocol ip parent 1: prio 1 u32 match ip dst \
+	192.168.1.100 action skbedit queue_mapping 2
+
+These commands tell the kernel to attach a multiqueue queue discipline to the
+bond0 interface and filter traffic enqueued to it, such that packets with a dst
+ip of 192.168.1.100 have their output queue mapping value overwritten to 2.
+This value is then passed into the driver, causing the normal output path
+selection policy to be overridden, selecting instead qid 2, which maps to eth1.
+
+Note that qid values begin at 1.  Qid 0 is reserved to initiate to the driver
+that normal output policy selection should take place.  One benefit to simply
+leaving the qid for a slave to 0 is the multiqueue awareness in the bonding
+driver that is now present.  This awareness allows tc filters to be placed on
+slave devices as well as bond devices and the bonding driver will simply act as
+a pass-through for selecting output queues on the slave device rather than 
+output port selection.
+
+This feature first appeared in bonding driver version 3.7.0 and support for
+output slave selection was limited to round-robin and active-backup modes.

+- CAIF SPI porting -
+
+- CAIF SPI basics:
+
+Running CAIF over SPI needs some extra setup, owing to the nature of SPI.
+Two extra GPIOs have been added in order to negotiate the transfers
+ between the master and the slave. The minimum requirement for running
+CAIF over SPI is a SPI slave chip and two GPIOs (more details below).
+Please note that running as a slave implies that you need to keep up
+with the master clock. An overrun or underrun event is fatal.
+
+- CAIF SPI framework:
+
+To make porting as easy as possible, the CAIF SPI has been divided in
+two parts. The first part (called the interface part) deals with all
+generic functionality such as length framing, SPI frame negotiation
+and SPI frame delivery and transmission. The other part is the CAIF
+SPI slave device part, which is the module that you have to write if
+you want to run SPI CAIF on a new hardware. This part takes care of
+the physical hardware, both with regard to SPI and to GPIOs.
+
+- Implementing a CAIF SPI device:
+
+	- Functionality provided by the CAIF SPI slave device:
+
+	In order to implement a SPI device you will, as a minimum,
+	need to implement the following
+	functions:
+
+	int (*init_xfer) (struct cfspi_xfer * xfer, struct cfspi_dev *dev):
+
+	This function is called by the CAIF SPI interface to give
+	you a chance to set up your hardware to be ready to receive
+	a stream of data from the master. The xfer structure contains
+	both physical and logical adresses, as well as the total length
+	of the transfer in both directions.The dev parameter can be used
+	to map to different CAIF SPI slave devices.
+
+	void (*sig_xfer) (bool xfer, struct cfspi_dev *dev):
+
+	This function is called by the CAIF SPI interface when the output
+	(SPI_INT) GPIO needs to change state. The boolean value of the xfer
+	variable indicates whether the GPIO should be asserted (HIGH) or
+	deasserted (LOW). The dev parameter can be used to map to different CAIF
+	SPI slave devices.
+
+	- Functionality provided by the CAIF SPI interface:
+
+	void (*ss_cb) (bool assert, struct cfspi_ifc *ifc);
+
+	This function is called by the CAIF SPI slave device in order to
+	signal a change of state of the input GPIO (SS) to the interface.
+	Only active edges are mandatory to be reported.
+	This function can be called from IRQ context (recommended in order
+	not to introduce latency). The ifc parameter should be the pointer
+	returned from the platform probe function in the SPI device structure.
+
+	void (*xfer_done_cb) (struct cfspi_ifc *ifc);
+
+	This function is called by the CAIF SPI slave device in order to
+	report that a transfer is completed. This function should only be
+	called once both the transmission and the reception are completed.
+	This function can be called from IRQ context (recommended in order
+	not to introduce latency). The ifc parameter should be the pointer
+	returned from the platform probe function in the SPI device structure.
+
+	- Connecting the bits and pieces:
+
+		- Filling in the SPI slave device structure:
+
+		Connect the necessary callback functions.
+		Indicate clock speed (used to calculate toggle delays).
+		Chose a suitable name (helps debugging if you use several CAIF
+		SPI slave devices).
+		Assign your private data (can be used to map to your structure).
+
+		- Filling in the SPI slave platform device structure:
+		Add name of driver to connect to ("cfspi_sspi").
+		Assign the SPI slave device structure as platform data.
+
+- Padding:
+
+In order to optimize throughput, a number of SPI padding options are provided.
+Padding can be enabled independently for uplink and downlink transfers.
+Padding can be enabled for the head, the tail and for the total frame size.
+The padding needs to be correctly configured on both sides of the link.
+The padding can be changed via module parameters in cfspi_sspi.c or via
+the sysfs directory of the cfspi_sspi driver (before device registration).

+			     DNS Resolver Module
+			     ===================
+
+Contents:
+
+ - Overview.
+ - Compilation.
+ - Setting up.
+ - Usage.
+ - Mechanism.
+ - Debugging.
+
+
+========
+OVERVIEW
+========
+
+The DNS resolver module provides a way for kernel services to make DNS queries
+by way of requesting a key of key type dns_resolver.  These queries are
+upcalled to userspace through /sbin/request-key.
+
+These routines must be supported by userspace tools dns.upcall, cifs.upcall and
+request-key.  It is under development and does not yet provide the full feature
+set.  The features it does support include:
+
+ (*) Implements the dns_resolver key_type to contact userspace.
+
+It does not yet support the following AFS features:
+
+ (*) Dns query support for AFSDB resource record.
+
+This code is extracted from the CIFS filesystem.
+
+
+===========
+COMPILATION
+===========
+
+The module should be enabled by turning on the kernel configuration options:
+
+	CONFIG_DNS_RESOLVER	- tristate "DNS Resolver support"
+
+
+==========
+SETTING UP
+==========
+
+To set up this facility, the /etc/request-key.conf file must be altered so that
+/sbin/request-key can appropriately direct the upcalls.  For example, to handle
+basic dname to IPv4/IPv6 address resolution, the following line should be
+added:
+
+	#OP	TYPE		DESC	CO-INFO	PROGRAM ARG1 ARG2 ARG3 ...
+	#======	============	=======	=======	==========================
+	create	dns_resolver  	*	*	/usr/sbin/cifs.upcall %k
+
+To direct a query for query type 'foo', a line of the following should be added
+before the more general line given above as the first match is the one taken.
+
+	create	dns_resolver  	foo:*	*	/usr/sbin/dns.foo %k
+
+
+
+=====
+USAGE
+=====
+
+To make use of this facility, one of the following functions that are
+implemented in the module can be called after doing:
+
+	#include <linux/dns_resolver.h>
+
+ (1) int dns_query(const char *type, const char *name, size_t namelen,
+		   const char *options, char **_result, time_t *_expiry);
+
+     This is the basic access function.  It looks for a cached DNS query and if
+     it doesn't find it, it upcalls to userspace to make a new DNS query, which
+     may then be cached.  The key description is constructed as a string of the
+     form:
+
+		[<type>:]<name>
+
+     where <type> optionally specifies the particular upcall program to invoke,
+     and thus the type of query to do, and <name> specifies the string to be
+     looked up.  The default query type is a straight hostname to IP address
+     set lookup.
+
+     The name parameter is not required to be a NUL-terminated string, and its
+     length should be given by the namelen argument.
+
+     The options parameter may be NULL or it may be a set of options
+     appropriate to the query type.
+
+     The return value is a string appropriate to the query type.  For instance,
+     for the default query type it is just a list of comma-separated IPv4 and
+     IPv6 addresses.  The caller must free the result.
+
+     The length of the result string is returned on success, and a negative
+     error code is returned otherwise.  -EKEYREJECTED will be returned if the
+     DNS lookup failed.
+
+     If _expiry is non-NULL, the expiry time (TTL) of the result will be
+     returned also.
+
+
+=========
+MECHANISM
+=========
+
+The dnsresolver module registers a key type called "dns_resolver".  Keys of
+this type are used to transport and cache DNS lookup results from userspace.
+
+When dns_query() is invoked, it calls request_key() to search the local
+keyrings for a cached DNS result.  If that fails to find one, it upcalls to
+userspace to get a new result.
+
+Upcalls to userspace are made through the request_key() upcall vector, and are
+directed by means of configuration lines in /etc/request-key.conf that tell
+/sbin/request-key what program to run to instantiate the key.
+
+The upcall handler program is responsible for querying the DNS, processing the
+result into a form suitable for passing to the keyctl_instantiate_key()
+routine.  This then passes the data to dns_resolver_instantiate() which strips
+off and processes any options included in the data, and then attaches the
+remainder of the string to the key as its payload.
+
+The upcall handler program should set the expiry time on the key to that of the
+lowest TTL of all the records it has extracted a result from.  This means that
+the key will be discarded and recreated when the data it holds has expired.
+
+dns_query() returns a copy of the value attached to the key, or an error if
+that is indicated instead.
+
+See <file:Documentation/keys-request-key.txt> for further information about
+request-key function.

+processors are allowed to use as the serialization callback processor.
+The workqueue wq is where the work will actually be done; it should be
+a multithreaded queue, naturally.
+
+To allocate a padata instance with the cpu_possible_mask for both
+cpumasks this helper function can be used:
+
+    struct padata_instance *padata_alloc_possible(struct workqueue_struct *wq);
+
+Note: Padata maintains two kinds of cpumasks internally. The user supplied
+cpumasks, submitted by padata_alloc/padata_alloc_possible and the 'usable'
+cpumasks. The usable cpumasks are always the subset of active cpus in the
+user supplied cpumasks, these are the cpumasks padata actually use. So
+it is legal to supply a cpumask to padata that contains offline cpus.
+Once a offline cpu in the user supplied cpumask comes online, padata
+is going to use it.
 
 There are functions for enabling and disabling the instance:
 
-    void padata_start(struct padata_instance *pinst);
+    int padata_start(struct padata_instance *pinst);
     void padata_stop(struct padata_instance *pinst);
 
-These functions literally do nothing beyond setting or clearing the
-"padata_start() was called" flag; if that flag is not set, other functions
-will refuse to work.
+These functions are setting or clearing the "PADATA_INIT" flag;
+if that flag is not set, other functions will refuse to work.
+padata_start returns zero on success (flag set) or -EINVAL if the
+padata cpumask contains no active cpu (flag not set).
+padata_stop clears the flag and blocks until the padata instance
+is unused.
 
 The list of CPUs to be used can be adjusted with these functions:
 
-    int padata_set_cpumask(struct padata_instance *pinst,
+    int padata_set_cpumasks(struct padata_instance *pinst,
+			    cpumask_var_t pcpumask,
+			    cpumask_var_t cbcpumask);
+    int padata_set_cpumask(struct padata_instance *pinst, int cpumask_type,
 			   cpumask_var_t cpumask);
-    int padata_add_cpu(struct padata_instance *pinst, int cpu);

+    int padata_add_cpu(struct padata_instance *pinst, int cpu, int mask);
+    int padata_remove_cpu(struct padata_instance *pinst, int cpu, int mask);
+
+Changing the CPU masks are expensive operations, though, so it should not be
+done with great frequency.
+
+It's possible to change both cpumasks of a padata instance with
+padata_set_cpumasks by specifying the cpumasks for parallel execution (pcpumask)
+and for the serial callback function (cbcpumask). padata_set_cpumask is to
+change just one of the cpumasks. Here cpumask_type is one of PADATA_CPU_SERIAL,
+PADATA_CPU_PARALLEL and cpumask specifies the new cpumask to use.
+To simply add or remove one cpu from a certain cpumask the functions
+padata_add_cpu/padata_remove_cpu are used. cpu specifies the cpu to add or
+remove and mask is one of PADATA_CPU_SERIAL, PADATA_CPU_PARALLEL.
+
+If a user is interested in padata cpumask changes, he can register to
+the padata cpumask change notifier:
+
+    int padata_register_cpumask_notifier(struct padata_instance *pinst,
+					 struct notifier_block *nblock);
+
+To unregister from that notifier:
+
+    int padata_unregister_cpumask_notifier(struct padata_instance *pinst,
+					   struct notifier_block *nblock);
+
+The padata cpumask change notifier notifies about changes of the usable
+cpumasks, i.e. the subset of active cpus in the user supplied cpumask.
+
+Padata calls the notifier chain with:
+
+    blocking_notifier_call_chain(&pinst->cpumask_change_notifier,
+				 notification_mask,

-Changing the CPU mask has the look of an expensive operation, though, so it

+HPSA - Hewlett Packard Smart Array driver
+-----------------------------------------
+
+This file describes the hpsa SCSI driver for HP Smart Array controllers.
+The hpsa driver is intended to supplant the cciss driver for newer
+Smart Array controllers.  The hpsa driver is a SCSI driver, while the
+cciss driver is a "block" driver.  Actually cciss is both a block
+driver (for logical drives) AND a SCSI driver (for tape drives). This
+"split-brained" design of the cciss driver is a source of excess
+complexity and eliminating that complexity is one of the reasons
+for hpsa to exist.
+
+Supported devices:
+------------------
+
+Smart Array P212
+Smart Array P410
+Smart Array P410i
+Smart Array P411
+Smart Array P812
+Smart Array P712m
+Smart Array P711m
+StorageWorks P1210m
+
+Additionally, older Smart Arrays may work with the hpsa driver if the kernel
+boot parameter "hpsa_allow_any=1" is specified, however these are not tested
+nor supported by HP with this driver.  For older Smart Arrays, the cciss
+driver should still be used.
+
+HPSA specific entries in /sys
+-----------------------------
+
+  In addition to the generic SCSI attributes available in /sys, hpsa supports
+  the following attributes:
+
+  HPSA specific host attributes:
+  ------------------------------
+
+  /sys/class/scsi_host/host*/rescan
+  /sys/class/scsi_host/host*/firmware_revision
+
+  the host "rescan" attribute is a write only attribute.  Writing to this
+  attribute will cause the driver to scan for new, changed, or removed devices
+  (e.g. hot-plugged tape drives, or newly configured or deleted logical drives,
+  etc.) and notify the SCSI midlayer of any changes detected.  Normally this is
+  triggered automatically by HP's Array Configuration Utility (either the GUI or
+  command line variety) so for logical drive changes, the user should not
+  normally have to use this.  It may be useful when hot plugging devices like
+  tape drives, or entire storage boxes containing pre-configured logical drives.
+
+  The "firmware_revision" attribute contains the firmware version of the Smart Array.
+  For example:
+
+	root@host:/sys/class/scsi_host/host4# cat firmware_revision
+	7.14
+
+  HPSA specific disk attributes:
+  ------------------------------
+
+  /sys/class/scsi_disk/c:b:t:l/device/unique_id
+  /sys/class/scsi_disk/c:b:t:l/device/raid_level
+  /sys/class/scsi_disk/c:b:t:l/device/lunid
+
+  (where c:b:t:l are the controller, bus, target and lun of the device)
+
+  For example:
+
+	root@host:/sys/class/scsi_disk/4:0:0:0/device# cat unique_id
+	600508B1001044395355323037570F77
+	root@host:/sys/class/scsi_disk/4:0:0:0/device# cat lunid
+	0x0000004000000000
+	root@host:/sys/class/scsi_disk/4:0:0:0/device# cat raid_level
+	RAID 0
+
+HPSA specific ioctls:
+---------------------
+
+  For compatibility with applications written for the cciss driver, many, but
+  not all of the ioctls supported by the cciss driver are also supported by the
+  hpsa driver.  The data structures used by these are described in
+  include/linux/cciss_ioctl.h
+
+  CCISS_DEREGDISK
+  CCISS_REGNEWDISK
+  CCISS_REGNEWD
+
+  The above three ioctls all do exactly the same thing, which is to cause the driver
+  to rescan for new devices.  This does exactly the same thing as writing to the
+  hpsa specific host "rescan" attribute.
+
+  CCISS_GETPCIINFO
+
+	Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID).
+
+  CCISS_GETDRIVVER
+
+	Returns driver version in three bytes encoded as:
+		(major_version << 16) | (minor_version << 8) | (subminor_version)
+
+  CCISS_PASSTHRU
+  CCISS_BIG_PASSTHRU
+
+	Allows "BMIC" and "CISS" commands to be passed through to the Smart Array.
+	These are used extensively by the HP Array Configuration Utility, SNMP storage
+	agents, etc.  See cciss_vol_status at http://cciss.sf.net for some examples.

-Typically, when processing something, these items will spend a lot of time
-blocking a thread on I/O, thus making that thread unavailable for doing other
-work.
-
-The standard workqueue model is unsuitable for this class of work item as that
-limits the owner to a single thread or a single thread per CPU.  For some
-tasks, however, more threads - or fewer - are required.
-
-There is just one pool per system.  It contains no threads unless something
-wants to use it - and that something must register its interest first.  When
-the pool is active, the number of threads it contains is dynamic, varying
-between a maximum and minimum setting, depending on the load.
-
-
-====================
-CLASSES OF WORK ITEM
-====================
-
-This pool support two classes of work items:
-
- (*) Slow work items.
-
- (*) Very slow work items.
-
-The former are expected to finish much quicker than the latter.
-
-An operation of the very slow class may do a batch combination of several
-lookups, mkdirs, and a create for instance.
-
-An operation of the ordinarily slow class may, for example, write stuff or
-expand files, provided the time taken to do so isn't too long.
-
-Operations of both types may sleep during execution, thus tying up the thread
-loaned to it.
-
-A further class of work item is available, based on the slow work item class:
-
- (*) Delayed slow work items.
-
-These are slow work items that have a timer to defer queueing of the item for
-a while.
-
-
-THREAD-TO-CLASS ALLOCATION
---------------------------
-
-Not all the threads in the pool are available to work on very slow work items.
-The number will be between one and one fewer than the number of active threads.
-This is configurable (see the "Pool Configuration" section).
-
-All the threads are available to work on ordinarily slow work items, but a
-percentage of the threads will prefer to work on very slow work items.
-
-The configuration ensures that at least one thread will be available to work on
-very slow work items, and at least one thread will be available that won't work
-on very slow work items at all.
-
-
-=====================
-USING SLOW WORK ITEMS
-=====================
-
-Firstly, a module or subsystem wanting to make use of slow work items must
-register its interest:
-
-	 int ret = slow_work_register_user(struct module *module);
-
-This will return 0 if successful, or a -ve error upon failure.  The module
-pointer should be the module interested in using this facility (almost
-certainly THIS_MODULE).
-
-
-Slow work items may then be set up by:
-
- (1) Declaring a slow_work struct type variable:
-
-	#include <linux/slow-work.h>
-
-	struct slow_work myitem;
-
- (2) Declaring the operations to be used for this item:
-
-	struct slow_work_ops myitem_ops = {
-		.get_ref = myitem_get_ref,
-		.put_ref = myitem_put_ref,
-		.execute = myitem_execute,
-	};
-
-     [*] For a description of the ops, see section "Item Operations".
-
- (3) Initialising the item:
-
-	slow_work_init(&myitem, &myitem_ops);
-
-     or:
-
-	delayed_slow_work_init(&myitem, &myitem_ops);
-
-     or:
-
-	vslow_work_init(&myitem, &myitem_ops);
-
-     depending on its class.
-
-A suitably set up work item can then be enqueued for processing:
-
-	int ret = slow_work_enqueue(&myitem);
-
-This will return a -ve error if the thread pool is unable to gain a reference
-on the item, 0 otherwise, or (for delayed work):
-
-	int ret = delayed_slow_work_enqueue(&myitem, my_jiffy_delay);
-
-
-The items are reference counted, so there ought to be no need for a flush
-operation.  But as the reference counting is optional, means to cancel
-existing work items are also included:
-
-	cancel_slow_work(&myitem);
-	cancel_delayed_slow_work(&myitem);
-
-can be used to cancel pending work.  The above cancel function waits for
-existing work to have been executed (or prevent execution of them, depending
-on timing).
-
-
-When all a module's slow work items have been processed, and the
-module has no further interest in the facility, it should unregister its
-interest:
-
-	slow_work_unregister_user(struct module *module);
-
-The module pointer is used to wait for all outstanding work items for that
-module before completing the unregistration.  This prevents the put_ref() code
-from being taken away before it completes.  module should almost certainly be
-THIS_MODULE.
-
-
-================
-HELPER FUNCTIONS
-================
-
-The slow-work facility provides a function by which it can be determined
-whether or not an item is queued for later execution:
-
-	bool queued = slow_work_is_queued(struct slow_work *work);
-
-If it returns false, then the item is not on the queue (it may be executing
-with a requeue pending).  This can be used to work out whether an item on which
-another depends is on the queue, thus allowing a dependent item to be queued
-after it.
-
-If the above shows an item on which another depends not to be queued, then the
-owner of the dependent item might need to wait.  However, to avoid locking up
-the threads unnecessarily be sleeping in them, it can make sense under some
-circumstances to return the work item to the queue, thus deferring it until
-some other items have had a chance to make use of the yielded thread.
-
-To yield a thread and defer an item, the work function should simply enqueue
-the work item again and return.  However, this doesn't work if there's nothing
-actually on the queue, as the thread just vacated will jump straight back into
-the item's work function, thus busy waiting on a CPU.
-
-Instead, the item should use the thread to wait for the dependency to go away,
-but rather than using schedule() or schedule_timeout() to sleep, it should use
-the following function:
-
-	bool requeue = slow_work_sleep_till_thread_needed(
-			struct slow_work *work,
-			signed long *_timeout);
-
-This will add a second wait and then sleep, such that it will be woken up if
-either something appears on the queue that could usefully make use of the
-thread - and behind which this item can be queued, or if the event the caller
-set up to wait for happens.  True will be returned if something else appeared
-on the queue and this work function should perhaps return, of false if
-something else woke it up.  The timeout is as for schedule_timeout().
-
-For example:
-
-	wq = bit_waitqueue(&my_flags, MY_BIT);
-	init_wait(&wait);
-	requeue = false;
-	do {
-		prepare_to_wait(wq, &wait, TASK_UNINTERRUPTIBLE);
-		if (!test_bit(MY_BIT, &my_flags))
-			break;
-		requeue = slow_work_sleep_till_thread_needed(&my_work,
-							     &timeout);
-	} while (timeout > 0 && !requeue);
-	finish_wait(wq, &wait);
-	if (!test_bit(MY_BIT, &my_flags)
-		goto do_my_thing;
-	if (requeue)
-		return; // to slow_work
-
-
-===============
-ITEM OPERATIONS
-===============
-
-Each work item requires a table of operations of type struct slow_work_ops.
-Only ->execute() is required; the getting and putting of a reference and the
-describing of an item are all optional.
-
- (*) Get a reference on an item:
-
-	int (*get_ref)(struct slow_work *work);
-
-     This allows the thread pool to attempt to pin an item by getting a
-     reference on it.  This function should return 0 if the reference was
-     granted, or a -ve error otherwise.  If an error is returned,
-     slow_work_enqueue() will fail.
-
-     The reference is held whilst the item is queued and whilst it is being
-     executed.  The item may then be requeued with the same reference held, or
-     the reference will be released.
-
- (*) Release a reference on an item:
-
-	void (*put_ref)(struct slow_work *work);
-
-     This allows the thread pool to unpin an item by releasing the reference on
-     it.  The thread pool will not touch the item again once this has been
-     called.
-
- (*) Execute an item:
-
-	void (*execute)(struct slow_work *work);
-
-     This should perform the work required of the item.  It may sleep, it may
-     perform disk I/O and it may wait for locks.
-
- (*) View an item through /proc:
-
-	void (*desc)(struct slow_work *work, struct seq_file *m);
-
-     If supplied, this should print to 'm' a small string describing the work
-     the item is to do.  This should be no more than about 40 characters, and
-     shouldn't include a newline character.
-
-     See the 'Viewing executing and queued items' section below.
-
-
-==================
-POOL CONFIGURATION
-==================
-
-The slow-work thread pool has a number of configurables:
-
- (*) /proc/sys/kernel/slow-work/min-threads
-
-     The minimum number of threads that should be in the pool whilst it is in
-     use.  This may be anywhere between 2 and max-threads.
-
- (*) /proc/sys/kernel/slow-work/max-threads
-
-     The maximum number of threads that should in the pool.  This may be
-     anywhere between min-threads and 255 or NR_CPUS * 2, whichever is greater.
-
- (*) /proc/sys/kernel/slow-work/vslow-percentage
-
-     The percentage of active threads in the pool that may be used to execute
-     very slow work items.  This may be between 1 and 99.  The resultant number
-     is bounded to between 1 and one fewer than the number of active threads.
-     This ensures there is always at least one thread that can process very
-     slow work items, and always at least one thread that won't.
-
-
-==================================
-VIEWING EXECUTING AND QUEUED ITEMS
-==================================
-
-If CONFIG_SLOW_WORK_DEBUG is enabled, a debugfs file is made available:
-
-	/sys/kernel/debug/slow_work/runqueue
-
-through which the list of work items being executed and the queues of items to
-be executed may be viewed.  The owner of a work item is given the chance to
-add some information of its own.
-
-The contents look something like the following:

+delays - Information on the various kernel delay / sleep mechanisms
+-------------------------------------------------------------------
+
+This document seeks to answer the common question: "What is the
+RightWay (TM) to insert a delay?"
+
+This question is most often faced by driver writers who have to
+deal with hardware delays and who may not be the most intimately
+familiar with the inner workings of the Linux Kernel.
+
+
+Inserting Delays
+----------------
+
+The first, and most important, question you need to ask is "Is my
+code in an atomic context?"  This should be followed closely by "Does
+it really need to delay in atomic context?" If so...
+
+ATOMIC CONTEXT:
+	You must use the *delay family of functions. These
+	functions use the jiffie estimation of clock speed
+	and will busy wait for enough loop cycles to achieve
+	the desired delay:
+
+	ndelay(unsigned long nsecs)
+	udelay(unsigned long usecs)
+	mdelay(unsgined long msecs)
+
+	udelay is the generally preferred API; ndelay-level
+	precision may not actually exist on many non-PC devices.
+
+	mdelay is macro wrapper around udelay, to account for
+	possible overflow when passing large arguments to udelay.
+	In general, use of mdelay is discouraged and code should
+	be refactored to allow for the use of msleep.
+
+NON-ATOMIC CONTEXT:
+	You should use the *sleep[_range] family of functions.
+	There are a few more options here, while any of them may
+	work correctly, using the "right" sleep function will
+	help the scheduler, power management, and just make your
+	driver better :)
+
+	-- Backed by busy-wait loop:
+		udelay(unsigned long usecs)
+	-- Backed by hrtimers:
+		usleep_range(unsigned long min, unsigned long max)
+	-- Backed by jiffies / legacy_timers
+		msleep(unsigned long msecs)
+		msleep_interruptible(unsigned long msecs)
+
+	Unlike the *delay family, the underlying mechanism
+	driving each of these calls varies, thus there are
+	quirks you should be aware of.
+
+
+	SLEEPING FOR "A FEW" USECS ( < ~10us? ):
+		* Use udelay
+
+		- Why not usleep?
+			On slower systems, (embedded, OR perhaps a speed-
+			stepped PC!) the overhead of setting up the hrtimers
+			for usleep *may* not be worth it. Such an evaluation
+			will obviously depend on your specific situation, but
+			it is something to be aware of.
+
+	SLEEPING FOR ~USECS OR SMALL MSECS ( 10us - 20ms):
+		* Use usleep_range
+
+		- Why not msleep for (1ms - 20ms)?
+			Explained originally here:
+				http://lkml.org/lkml/2007/8/3/250
+			msleep(1~20) may not do what the caller intends, and
+			will often sleep longer (~20 ms actual sleep for any
+			value given in the 1~20ms range). In many cases this
+			is not the desired behavior.
+
+		- Why is there no "usleep" / What is a good range?
+			Since usleep_range is built on top of hrtimers, the
+			wakeup will be very precise (ish), thus a simple
+			usleep function would likely introduce a large number
+			of undesired interrupts.
+
+			With the introduction of a range, the scheduler is
+			free to coalesce your wakeup with any other wakeup
+			that may have happened for other reasons, or at the
+			worst case, fire an interrupt for your upper bound.
+
+			The larger a range you supply, the greater a chance
+			that you will not trigger an interrupt; this should
+			be balanced with what is an acceptable upper bound on
+			delay / performance for your specific code path. Exact
+			tolerances here are very situation specific, thus it
+			is left to the caller to determine a reasonable range.
+
+	SLEEPING FOR LARGER MSECS ( 10ms+ )
+		* Use msleep or possibly msleep_interruptible
+
+		- What's the difference?
+			msleep sets the current task to TASK_UNINTERRUPTIBLE
+			whereas msleep_interruptible sets the current task to
+			TASK_INTERRUPTIBLE before scheduling the sleep. In
+			short, the difference is whether the sleep can be ended
+			early by a signal. In general, just use msleep unless
+			you know you have a need for the interruptible variant.

+See scripts/recordmcount.pl for more info.  Just fill in the arch-specific
+details for how to locate the addresses of mcount call sites via objdump.
+This option doesn't make much sense without also implementing dynamic ftrace.
 
+
+HAVE_DYNAMIC_FTRACE
+-------------------
+
+You will first need HAVE_FTRACE_MCOUNT_RECORD and HAVE_FUNCTION_TRACER, so
+scroll your reader back up if you got over eager.
+
+Once those are out of the way, you will need to implement:
+	- asm/ftrace.h:
+		- MCOUNT_ADDR
+		- ftrace_call_adjust()
+		- struct dyn_arch_ftrace{}
+	- asm code:
+		- mcount() (new stub)
+		- ftrace_caller()
+		- ftrace_call()
+		- ftrace_stub()
+	- C code:
+		- ftrace_dyn_arch_init()
+		- ftrace_make_nop()
+		- ftrace_make_call()
+		- ftrace_update_ftrace_func()
+
+First you will need to fill out some arch details in your asm/ftrace.h.
+
+Define MCOUNT_ADDR as the address of your mcount symbol similar to:
+	#define MCOUNT_ADDR ((unsigned long)mcount)
+Since no one else will have a decl for that function, you will need to:
+	extern void mcount(void);
+
+You will also need the helper function ftrace_call_adjust().  Most people
+will be able to stub it out like so:
+	static inline unsigned long ftrace_call_adjust(unsigned long addr)
+	{
+		return addr;
+	}
 <details to be filled>
 
+Lastly you will need the custom dyn_arch_ftrace structure.  If you need
+some extra state when runtime patching arbitrary call sites, this is the
+place.  For now though, create an empty struct:
+	struct dyn_arch_ftrace {
+		/* No extra data needed */
+	};
+
+With the header out of the way, we can fill out the assembly code.  While we
+did already create a mcount() function earlier, dynamic ftrace only wants a
+stub function.  This is because the mcount() will only be used during boot
+and then all references to it will be patched out never to return.  Instead,
+the guts of the old mcount() will be used to create a new ftrace_caller()
+function.  Because the two are hard to merge, it will most likely be a lot
+easier to have two separate definitions split up by #ifdefs.  Same goes for
+the ftrace_stub() as that will now be inlined in ftrace_caller().
+
+Before we get confused anymore, let's check out some pseudo code so you can
+implement your own stuff in assembly:
 
-HAVE_DYNAMIC_FTRACE
----------------------
+void mcount(void)
+{
+	return;
+}
+
+void ftrace_caller(void)
+{
+	/* implement HAVE_FUNCTION_TRACE_MCOUNT_TEST if you desire */
+
+	/* save all state needed by the ABI (see paragraph above) */
+
+	unsigned long frompc = ...;
+	unsigned long selfpc = <return address> - MCOUNT_INSN_SIZE;
+
+ftrace_call:
+	ftrace_stub(frompc, selfpc);
+
+	/* restore all state needed by the ABI */
+
+ftrace_stub:
+	return;
+}
+
+This might look a little odd at first, but keep in mind that we will be runtime
+patching multiple things.  First, only functions that we actually want to trace
+will be patched to call ftrace_caller().  Second, since we only have one tracer
+active at a time, we will patch the ftrace_caller() function itself to call the
+specific tracer in question.  That is the point of the ftrace_call label.
+
+With that in mind, let's move on to the C code that will actually be doing the
+runtime patching.  You'll need a little knowledge of your arch's opcodes in
+order to make it through the next section.
+
+Every arch has an init callback function.  If you need to do something early on
+to initialize some state, this is the time to do that.  Otherwise, this simple
+function below should be sufficient for most people:
+
+int __init ftrace_dyn_arch_init(void *data)
+{
+	/* return value is done indirectly via data */
+	*(unsigned long *)data = 0;
+
+	return 0;
+}
+
+There are two functions that are used to do runtime patching of arbitrary
+functions.  The first is used to turn the mcount call site into a nop (which
+is what helps us retain runtime performance when not tracing).  The second is
+used to turn the mcount call site into a call to an arbitrary location (but
+typically that is ftracer_caller()).  See the general function definition in
+linux/ftrace.h for the functions:
+	ftrace_make_nop()
+	ftrace_make_call()
+The rec->ip value is the address of the mcount call site that was collected
+by the scripts/recordmcount.pl during build time.
+
+The last function is used to do runtime patching of the active tracer.  This
+will be modifying the assembly code at the location of the ftrace_call symbol
+inside of the ftrace_caller() function.  So you should have sufficient padding
+at that location to support the new function calls you'll be inserting.  Some
+people will be using a "call" type instruction while others will be using a
+"branch" type instruction.  Specifically, the function is:
+	ftrace_update_ftrace_func()
+
+
+HAVE_DYNAMIC_FTRACE + HAVE_FUNCTION_GRAPH_TRACER
+------------------------------------------------
+
+The function grapher needs a few tweaks in order to work with dynamic ftrace.
+Basically, you will need to:
+	- update:
+		- ftrace_caller()
+		- ftrace_graph_call()
+		- ftrace_graph_caller()
+	- implement:
+		- ftrace_enable_ftrace_graph_caller()
+		- ftrace_disable_ftrace_graph_caller()
 
 <details to be filled>
+Quick notes:
+	- add a nop stub after the ftrace_call location named ftrace_graph_call;
+	  stub needs to be large enough to support a call to ftrace_graph_caller()
+	- update ftrace_graph_caller() to work with being called by the new
+	  ftrace_caller() since some semantics may have changed
+	- ftrace_enable_ftrace_graph_caller() will runtime patch the
+	  ftrace_graph_call location with a call to ftrace_graph_caller()
+	- ftrace_disable_ftrace_graph_caller() will runtime patch the
+	  ftrace_graph_call location with nops

-			kmemtrace - Kernel Memory Tracer
-
-			  by Eduard - Gabriel Munteanu
-			     <eduard.munteanu@linux360.ro>
-
-I. Introduction
-===============
-
-kmemtrace helps kernel developers figure out two things:
-1) how different allocators (SLAB, SLUB etc.) perform
-2) how kernel code allocates memory and how much
-
-To do this, we trace every allocation and export information to the userspace
-through the relay interface. We export things such as the number of requested
-bytes, the number of bytes actually allocated (i.e. including internal
-fragmentation), whether this is a slab allocation or a plain kmalloc() and so
-on.
-
-The actual analysis is performed by a userspace tool (see section III for
-details on where to get it from). It logs the data exported by the kernel,
-processes it and (as of writing this) can provide the following information:
-- the total amount of memory allocated and fragmentation per call-site
-- the amount of memory allocated and fragmentation per allocation
-- total memory allocated and fragmentation in the collected dataset
-- number of cross-CPU allocation and frees (makes sense in NUMA environments)
-
-Moreover, it can potentially find inconsistent and erroneous behavior in
-kernel code, such as using slab free functions on kmalloc'ed memory or
-allocating less memory than requested (but not truly failed allocations).
-
-kmemtrace also makes provisions for tracing on some arch and analysing the
-data on another.
-
-II. Design and goals
-====================
-
-kmemtrace was designed to handle rather large amounts of data. Thus, it uses
-the relay interface to export whatever is logged to userspace, which then
-stores it. Analysis and reporting is done asynchronously, that is, after the
-data is collected and stored. By design, it allows one to log and analyse
-on different machines and different arches.
-
-As of writing this, the ABI is not considered stable, though it might not
-change much. However, no guarantees are made about compatibility yet. When
-deemed stable, the ABI should still allow easy extension while maintaining
-backward compatibility. This is described further in Documentation/ABI.
-
-Summary of design goals:
-	- allow logging and analysis to be done across different machines
-	- be fast and anticipate usage in high-load environments (*)
-	- be reasonably extensible
-	- make it possible for GNU/Linux distributions to have kmemtrace
-	included in their repositories
-
-(*) - one of the reasons Pekka Enberg's original userspace data analysis
-    tool's code was rewritten from Perl to C (although this is more than a
-    simple conversion)
-
-
-III. Quick usage guide
-======================
-
-1) Get a kernel that supports kmemtrace and build it accordingly (i.e. enable
-CONFIG_KMEMTRACE).
-
-2) Get the userspace tool and build it:
-$ git clone git://repo.or.cz/kmemtrace-user.git		# current repository
-$ cd kmemtrace-user/
-$ ./autogen.sh
-$ ./configure
-$ make
-
-3) Boot the kmemtrace-enabled kernel if you haven't, preferably in the
-'single' runlevel (so that relay buffers don't fill up easily), and run
-kmemtrace:
-# '$' does not mean user, but root here.
-$ mount -t debugfs none /sys/kernel/debug
-$ mount -t proc none /proc
-$ cd path/to/kmemtrace-user/
-$ ./kmemtraced
-Wait a bit, then stop it with CTRL+C.
-$ cat /sys/kernel/debug/kmemtrace/total_overruns	# Check if we didn't
-							# overrun, should
-							# be zero.
-$ (Optionally) [Run kmemtrace_check separately on each cpu[0-9]*.out file to
-		check its correctness]
-$ ./kmemtrace-report
-
-Now you should have a nice and short summary of how the allocator performs.
-
-IV. FAQ and known issues
-========================
-
-Q: 'cat /sys/kernel/debug/kmemtrace/total_overruns' is non-zero, how do I fix
-this? Should I worry?
-A: If it's non-zero, this affects kmemtrace's accuracy, depending on how
-large the number is. You can fix it by supplying a higher
-'kmemtrace.subbufs=N' kernel parameter.
----
-
-Q: kmemtrace_check reports errors, how do I fix this? Should I worry?
-A: This is a bug and should be reported. It can occur for a variety of
-reasons:
-	- possible bugs in relay code
-	- possible misuse of relay by kmemtrace
-	- timestamps being collected unorderly
-Or you may fix it yourself and send us a patch.
----
-
-Q: kmemtrace_report shows many errors, how do I fix this? Should I worry?
-A: This is a known issue and I'm working on it. These might be true errors
-in kernel code, which may have inconsistent behavior (e.g. allocating memory
-with kmem_cache_alloc() and freeing it with kfree()). Pekka Enberg pointed
-out this behavior may work with SLAB, but may fail with other allocators.
-
-It may also be due to lack of tracing in some unusual allocator functions.
-
-We don't want bug reports regarding this issue yet.

+ * LPC32xx clock management driver overview
+ *
+ * The LPC32XX contains a number of high level system clocks that can be
+ * generated from different sources. These system clocks are used to
+ * generate the CPU and bus rates and the individual peripheral clocks in
+ * the system. When Linux is started by the boot loader, the system
+ * clocks are already running. Stopping a system clock during normal
+ * Linux operation should never be attempted, as peripherals that require
+ * those clocks will quit working (ie, DRAM).
+ *
+ * The LPC32xx high level clock tree looks as follows. Clocks marked with
+ * an asterisk are always on and cannot be disabled. Clocks marked with
+ * an ampersand can only be disabled in CPU suspend mode. Clocks marked
+ * with a caret are always on if it is the selected clock for the SYSCLK
+ * source. The clock that isn't used for SYSCLK can be enabled and
+ * disabled normally.

+ * The CPU and chip bus rates are derived from the HCLK PLL, which can
+ * generate various clock rates up to 266MHz and beyond. The internal bus
+ * rates (PCLK and HCLK) are generated from dividers based on the HCLK
+ * PLL rate. HCLK can be a ratio of 1:1, 1:2, or 1:4 or HCLK PLL rate,
+ * while PCLK can be 1:1 to 1:32 of HCLK PLL rate. Most peripherals high
+ * level clocks are based on either HCLK or PCLK, but have their own
+ * dividers as part of the IP itself. Because of this, the system clock
+ * rates should not be changed.
+ *
+ * The HCLK PLL is clocked from SYSCLK, which can be derived from the
+ * main oscillator or PLL397. PLL397 generates a rate that is 397 times
+ * the 32KHz oscillator rate. The main oscillator runs at the selected
+ * oscillator/crystal rate on the mosc_in pin of the LPC32xx. This rate
+ * is normally 13MHz, but depends on the selection of external crystals
+ * or oscillators. If USB operation is required, the main oscillator must
+ * be used in the system.
+ *
+ * Switching SYSCLK between sources during normal Linux operation is not
+ * supported. SYSCLK is preset in the bootloader. Because of the
+ * complexities of clock management during clock frequency changes,
+ * there are some limitations to the clock driver explained below:
+ * - The PLL397 and main oscillator can be enabled and disabled by the
+ *   clk_enable() and clk_disable() functions unless SYSCLK is based
+ *   on that clock. This allows the other oscillator that isn't driving
+ *   the HCLK PLL to be used as another system clock that can be routed
+ *   to an external pin.
+ * - The muxed SYSCLK input and HCLK_PLL rate cannot be changed with
+ *   this driver.
+ * - HCLK and PCLK rates cannot be changed as part of this driver.
+ * - Most peripherals have their own dividers are part of the peripheral
+ *   block. Changing SYSCLK, HCLK PLL, HCLK, or PCLK sources or rates
+ *   will also impact the individual peripheral rates.

+/*
+ * LPC32XX CPU and system power management
+ *
+ * The LCP32XX has three CPU modes for controlling system power: run,
+ * direct-run, and halt modes. When switching between halt and run modes,
+ * the CPU transistions through direct-run mode. For Linux, direct-run
+ * mode is not used in normal operation. Halt mode is used when the
+ * system is fully suspended.
+ *
+ * Run mode:
+ * The ARM CPU clock (HCLK_PLL), HCLK bus clock, and PCLK bus clocks are
+ * derived from the HCLK PLL. The HCLK and PCLK bus rates are divided from
+ * the HCLK_PLL rate. Linux runs in this mode.
+ *
+ * Direct-run mode:
+ * The ARM CPU clock, HCLK bus clock, and PCLK bus clocks are driven from
+ * SYSCLK. SYSCLK is usually around 13MHz, but may vary based on SYSCLK
+ * source or the frequency of the main oscillator. In this mode, the
+ * HCLK_PLL can be safely enabled, changed, or disabled.
+ *
+ * Halt mode:
+ * SYSCLK is gated off and the CPU and system clocks are halted.
+ * Peripherals based on the 32KHz oscillator clock (ie, RTC, touch,
+ * key scanner, etc.) still operate if enabled. In this state, an enabled
+ * system event (ie, GPIO state change, RTC match, key press, etc.) will
+ * wake the system up back into direct-run mode.
+ *
+ * DRAM refresh
+ * DRAM clocking and refresh are slightly different for systems with DDR
+ * DRAM or regular SDRAM devices. If SDRAM is used in the system, the
+ * SDRAM will still be accessible in direct-run mode. In DDR based systems,
+ * a transistion to direct-run mode will stop all DDR accesses (no clocks).
+ * Because of this, the code to switch power modes and the code to enter
+ * and exit DRAM self-refresh modes must not be executed in DRAM. A small
+ * section of IRAM is used instead for this.
+ *
+ * Suspend is handled with the following logic:
+ *  Backup a small area of IRAM used for the suspend code
+ *  Copy suspend code to IRAM
+ *  Transfer control to code in IRAM
+ *  Places DRAMs in self-refresh mode
+ *  Enter direct-run mode
+ *  Save state of HCLK_PLL PLL
+ *  Disable HCLK_PLL PLL
+ *  Enter halt mode - CPU and buses will stop
+ *  System enters direct-run mode when an enabled event occurs
+ *  HCLK PLL state is restored
+ *  Run mode is entered
+ *  DRAMS are placed back into normal mode
+ *  Code execution returns from IRAM
+ *  IRAM code are used for suspend is restored
+ *  Suspend mode is exited

+ * sizes to the next higher power of two, i.e. the offset element will have
+ * 8, 16, 32, 64, etc. bits. This eliminates the need to mask off any
+ * bits.  Finally, we compute a shift value that puts the most significant
+ * bits of the offset into the most significant bits of the offset element.
+ * This makes it more efficient on processors without barrel shifters and
+ * easier to see the values if the conversion table is dumped in binary.

- * The semantics of XCHGCMP8B are a bit strange, this is why

- * be inside. This inlines well in most cases, the cached
- * cost is around ~38 cycles. (in the future we might want
- * to do an SIMD/3DNOW!/MMX/FPU 64-bit store here, but that
- * might have an implicit FPU-save as a cost, so it's not
- * clear which path to go.)
+ * CMPXCHG8B only writes to the target if we had the previous
+ * value in registers, otherwise it acts as a read and gives us the
+ * "new previous" value.  That is why there is a loop.  Preloading
+ * EDX:EAX is a performance optimization: in the common case it means
+ * we need only one locked operation.
  *
- * cmpxchg8b must be used with the lock prefix here to allow
- * the instruction to be executed atomically, see page 3-102
- * of the instruction set reference 24319102.pdf. We need
- * the reader side to see the coherent 64bit value.

 	 *
-	 * This opcode is meant to set NV_PFB_CFG0 (0x100200) appropriately so
-	 * that the hardware can correctly calculate how much VRAM it has
-	 * (and subsequently report that value in NV_PFB_CSTATUS (0x10020C))
+	 * This opcode is meant to set the PFB memory config registers
+	 * appropriately so that we can correctly calculate how much VRAM it
+	 * has (on nv10 and better chipsets the amount of installed VRAM is
+	 * subsequently reported in NV_PFB_CSTATUS (0x10020C)).
 	 *
-	 * The implementation of this opcode in general consists of two parts:
-	 * 1) determination of the memory bus width
-	 * 2) determination of how many of the card's RAM pads have ICs attached
+	 * The implementation of this opcode in general consists of several
+	 * parts:
 	 *
-	 * 1) is done by a cunning combination of writes to offsets 0x1c and
-	 * 0x3c in the framebuffer, and seeing whether the written values are
-	 * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0
+	 * 1) Determination of memory type and density. Only necessary for
+	 *    really old chipsets, the memory type reported by the strap bits
+	 *    (0x101000) is assumed to be accurate on nv05 and newer.
 	 *
-	 * 2) is done by a cunning combination of writes to an offset slightly
-	 * less than the maximum memory reported by NV_PFB_CSTATUS, then seeing
-	 * if the test pattern can be read back. This then affects bits 12-15 of
-	 * NV_PFB_CFG0
+	 * 2) Determination of the memory bus width. Usually done by a cunning
+	 *    combination of writes to offsets 0x1c and 0x3c in the fb, and
+	 *    seeing whether the written values are read back correctly.
 	 *
-	 * In this context a "cunning combination" may include multiple reads
-	 * and writes to varying locations, often alternating the test pattern
-	 * and 0, doubtless to make sure buffers are filled, residual charges
-	 * on tracks are removed etc.
+	 *    Only necessary on nv0x-nv1x and nv34, on the other cards we can
+	 *    trust the straps.
 	 *
-	 * Unfortunately, the "cunning combination"s mentioned above, and the
-	 * changes to the bits in NV_PFB_CFG0 differ with nearly every bios
-	 * trace I have.
+	 * 3) Determination of how many of the card's RAM pads have ICs
+	 *    attached, usually done by a cunning combination of writes to an
+	 *    offset slightly less than the maximum memory reported by
+	 *    NV_PFB_CSTATUS, then seeing if the test pattern can be read back.
 	 *
-	 * Therefore, we cheat and assume the value of NV_PFB_CFG0 with which
-	 * we started was correct, and use that instead
+	 * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io
+	 * logs of the VBIOS and kmmio traces of the binary driver POSTing the

+ * in turn also based on the lirc_atiusb driver by Paul Miller. The
+ * two mce drivers were merged into one by Jarod Wilson, with transmit
+ * support for the 1st-gen device added primarily by Patrick Calhoun,
+ * with a bit of tweaks by Jarod. Debugging improvements and proper
+ * support for what appears to be 3rd-gen hardware added by Jarod.
+ * Initial port from lirc driver to ir-core drivery by Jarod, based
+ * partially on a port to an earlier proposed IR infrastructure by
+ * Jon Smirl, which included enhancements and simplifications to the
+ * incoming IR buffer parsing routines.

- *  STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
- *
- * Thanks to STMicroelectronics for information on the usb commands, and
- * to Steve Miller at STM for his help and encouragement while I was
- * writing this driver.
- *
- * This driver is based heavily on the
- * Endpoints (formerly known as AOX) se401 USB Camera Driver
- * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
- *
- * Still somewhat based on the Linux ov511 driver.

- * Free Software Foundation; either version 2 of the License, or (at your

- * You should have received a copy of the GNU General Public License
- * along with this program; if not, write to the Free Software Foundation,
- * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * History:
- * ver 0.1 October, 2001. Initial attempt.
- *
- * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
- *                         function, made more stable (?)
- *
- * ver 0.21 Nov, 2001.     Added gamma correction and white balance,
- *                         due to Alexander Schwartz. Still trying to
- *                         improve stablility. Moved stuff into stv680.h
- *
- * ver 0.22 Nov, 2001.	   Added sharpen function (by Michael Sweet,
- *                         mike@easysw.com) from GIMP, also used in pencam.
- *                         Simple, fast, good integer math routine.
- *
- * ver 0.23 Dec, 2001 (gkh)
- * 			   Took out sharpen function, ran code through
- * 			   Lindent, and did other minor tweaks to get
- * 			   things to work properly with 2.5.1
- *
- * ver 0.24 Jan, 2002 (kjs)
- *                         Fixed the problem with webcam crashing after
- *                         two pictures. Changed the way pic is halved to
- *                         improve quality. Got rid of green line around
- *                         frame. Fix brightness reset when changing size
- *                         bug. Adjusted gamma filters slightly.
- *
- * ver 0.25 Jan, 2002 (kjs)
- *			   Fixed a bug in which the driver sometimes attempted
- *			   to set to a non-supported size. This allowed
- *			   gnomemeeting to work.
- *			   Fixed proc entry removal bug.

+ * cannot reserve enough PEBs for bad block handling. This function makes a
+ * decision whether we have to print a warning or not. The algorithm is as
+ * follows:
+ *   o if this is a new UBI image, then just print the warning
+ *   o if this is an UBI image which has already been used for some time, print
+ *     a warning only if we can reserve less than 10% of the expected amount of
+ *     the reserved PEB.
+ *
+ * The idea is that when UBI is used, PEBs become bad, and the reserved pool
+ * of PEBs becomes smaller, which is normal and we do not want to scare users
+ * with a warning every time they attach the MTD device. This was an issue
+ * reported by real users.

-    bind_request() connects a socket to a particular client driver.
-    It looks up the specified device ID in the list of registered
-    drivers, binds it to the socket, and tries to create an instance
-    of the device.  unbind_request() deletes a driver instance.

-    It is normally called by Driver Services after it has identified
-    a newly inserted card.  An instance of that driver will then be
-    eligible to register as a client of this socket.
-
-    Register_client() uses the dev_info_t handle to match the
-    caller with a socket.  The driver must have already been bound
-    to a socket with bind_device() -- in fact, bind_device()
-    allocates the client structure that will be used.

+ *   wake_up_XXX   Whether or not we listen to such wake up events (rw)
+ *
+ * In addition to these platform device attributes the driver
+ * registers itself in the Linux backlight control, power_supply, rfkill
+ * and hwmon subsystem and is available to userspace under:
+ *
+ *   /sys/class/backlight/compal-laptop/
+ *   /sys/class/power_supply/compal-laptop/
+ *   /sys/class/rfkill/rfkillX/
+ *   /sys/class/hwmon/hwmonX/
+ *
+ * Notes on the power_supply battery interface:
+ *   - the "minimum" design voltage is *the* design voltage
+ *   - the ambient temperature is the average battery temperature
+ *     and the value is an educated guess (see commented code below)
  *
- * The driver registers itself with the rfkill subsystem and
- * the Linux backlight control subsystem.
  *
  * This driver might work on other laptops produced by Compal. If you
  * want to try it you can pass force=1 as argument to the module which
  * will force it to load even when the DMI data doesn't identify the
- * laptop as FL9x.
+ * laptop as compatible.
+ *
+ * Lots of data available at:
+ * http://service1.marasst.com/Compal/JHL90_91/Service%20Manual/
+ * JHL90%20service%20manual-Final-0725.pdf
+ *
+ *
+ *
+ * Support for the Compal JHL90 added by Roald Frederickx
+ * (roald.frederickx@gmail.com):
+ * Driver got large revision. Added functionalities: backlight
+ * power, wake_on_XXX, a hwmon and power_supply interface.
+ *
+ * In case this gets merged into the kernel source: I want to dedicate this
+ * to Kasper Meerts, the awesome guy who showed me Linux and C!

+/*
+ * Some Intel Ibex Peak based platforms support so-called "intelligent
+ * power sharing", which allows the CPU and GPU to cooperate to maximize
+ * performance within a given TDP (thermal design point).  This driver
+ * performs the coordination between the CPU and GPU, monitors thermal and
+ * power statistics in the platform, and initializes power monitoring
+ * hardware.  It also provides a few tunables to control behavior.  Its
+ * primary purpose is to safely allow CPU and GPU turbo modes to be enabled
+ * by tracking power and thermal budget; secondarily it can boost turbo
+ * performance by allocating more power or thermal budget to the CPU or GPU
+ * based on available headroom and activity.
+ *
+ * The basic algorithm is driven by a 5s moving average of tempurature.  If
+ * thermal headroom is available, the CPU and/or GPU power clamps may be
+ * adjusted upwards.  If we hit the thermal ceiling or a thermal trigger,
+ * we scale back the clamp.  Aside from trigger events (when we're critically
+ * close or over our TDP) we don't adjust the clamps more than once every
+ * five seconds.
+ *
+ * The thermal device (device 31, function 6) has a set of registers that
+ * are updated by the ME firmware.  The ME should also take the clamp values
+ * written to those registers and write them to the CPU, but we currently
+ * bypass that functionality and write the CPU MSR directly.
+ *
+ * UNSUPPORTED:
+ *   - dual MCP configs
+ *
+ * TODO:
+ *   - handle CPU hotplug
+ *   - provide turbo enable/disable api
+ *   - make sure we can write turbo enable/disable reg based on MISC_EN
+ *

+                Each batman node only maintains information about its

+                feasible without having a central instance to collect
+                the local topologies from all nodes. This file allows
+                to activate the collecting (server) mode.

- * The previous block comment is used to automatically generate

- *
- * Driver: the name of the driver
- * Description: a short phrase describing the driver.  Don't list boards.
- * Devices: a full list of the boards that attempt to be supported by
- *   the driver.  Format is "(manufacturer) board name [comedi name]",
- *   where comedi_name is the name that is used to configure the board.
- *   See the comment near board_name: in the struct comedi_driver structure
- *   below.  If (manufacturer) or [comedi name] is missing, the previous
- *   value is used.
- * Author: you
- * Updated: date when the _documentation_ was last updated.  Use 'date -R'
- *   to get a value for this.
- * Status: a one-word description of the status.  Valid values are:
- *   works - driver works correctly on most boards supported, and
- *     passes comedi_test.
- *   unknown - unknown.  Usually put there by ds.
- *   experimental - may not work in any particular release.  Author
- *     probably wants assistance testing it.
- *   bitrotten - driver has not been update in a long time, probably
- *     doesn't work, and probably is missing support for significant
- *     Comedi interface features.
- *   untested - author probably wrote it "blind", and is believed to
- *     work, but no confirmation.
- *
- * These headers should be followed by a blank line, and any comments
- * you wish to say about the driver.  The comment area is the place
- * to put any known bugs, limitations, unsupported features, supported
- * command triggers, whether or not commands are supported on particular
- * subdevices, etc.
- *
- * Somewhere in the comment should be information about configuration
- * options that are used with comedi_config.

- *   where comedi_name is the name that is used to configure the board.
- *   See the comment near board_name: in the struct comedi_driver structure
- *   below.  If (manufacturer) or [comedi name] is missing, the previous
- *   value is used.
- * Author: you
- * Updated: date when the _documentation_ was last updated.  Use 'date -R'
- *   to get a value for this.
- * Status: a one-word description of the status.  Valid values are:
- *   works - driver works correctly on most boards supported, and
- *     passes comedi_test.
- *   unknown - unknown.  Usually put there by ds.
- *   experimental - may not work in any particular release.  Author
- *     probably wants assistance testing it.
- *   bitrotten - driver has not been update in a long time, probably
- *     doesn't work, and probably is missing support for significant
- *     Comedi interface features.
- *   untested - author probably wrote it "blind", and is believed to
- *     work, but no confirmation.
- *
- * These headers should be followed by a blank line, and any comments
- * you wish to say about the driver.  The comment area is the place
- * to put any known bugs, limitations, unsupported features, supported
- * command triggers, whether or not commands are supported on particular
- * subdevices, etc.
- *
- * Somewhere in the comment should be information about configuration
- * options that are used with comedi_config.

-The allocator shown here  exploits high memory. This document explains
-how  a user can  deal   with drivers uses   this  allocator and how  a
-programmer can link in the module.
-
-The module is being used by my pxc and pxdrv device drivers (as well as
-other ones), available from ftp.systemy.it/pub/develop and
-ftp.linux.it/pub/People/Rubini
-
-	User's manual
-	=============
-
-
-One of the most compelling problems with any DMA-capable device is the
-allocation  of a suitable  memory buffer. The "allocator" module tries
-to deal with  the problem in  a clean way.  The module is  able to use
-high   memory  (above the  one   used in  normal   operation)  for DMA
-allocation.
-
-To prevent  the  kernel for using   high memory,  so  that it  remains
-available for  DMA, you should  pass a  command  line argument to  the
-kernel.  Command line arguments  can be passed to  Lilo, to Loadlin or
-to whichever loader  you are using  (unless it's very poor in design).
-For Lilo, either use  "append=" in  /etc/lilo.conf or add  commandline
-arguments to the  interactive prompt. For  example, I have a 32MB  box
-and reserve two megs for DMA:
-
-In lilo.conf:
-	image = /zImage
-	label = linux
-	append = "mem=30M"
-
-Or, interactively:
-	LILO: linux mem=30M
-
-Once  the kernel is booted  with the  right command-line argument, any
-driver  linked   with  the  allocator   module  will  be able   to get
-DMA-capable memory without  much  trouble (unless the  various drivers
-need more memory than available).
-
-The module implements an alloc/free  mechanism,  so that it can  serve
-multiple drivers  at the  same time. Note  however that  the allocator
-uses all of  high memory and assumes to  be the only piece of software
-using such memory.
-
-
-	Programmer's manual
-	===================
-
-The allocator,  as  released, is designed  to  be linked  to  a device
-driver.  In this  case, the driver  must call allocator_init()  before
-using   the  allocator   and  must  call   allocator_cleanup()  before
-unloading.  This is  usually  done   from within  init_module()    and
-cleanup_module(). If the allocator is linked to  a driver, it won't be
-possible for several drivers to allocate high DMA memory, as explained
-above.
-
-It is possible, on the other hand, to compile the module as a standalone
-module, so that several modules can rely on the allocator for they DMA
-buffers. To compile the allocator as a standalone module, do the
-following in this directory (or provide a suitable Makefile, or edit
-the source code):
-
-	make allocator.o CC="gcc -Dallocator_init=init_module -Dallocator_cleanup=cleanup_module -include /usr/include/linux/module.h"
-
-The previous commandline  tells   to include <linux/module.h>  in  the
-first place,  and to rename the init  and cleanup function to the ones
-needed for  module loading and  unloading.  Drivers using a standalone
-allocator won't need to call allocator_init() nor allocator_cleanup().
-
-The allocator exports the following functions (declared in allocator.h):
-
-   unsigned long allocator_allocate_dma (unsigned long kilobytes,
-					 int priority);
-
-	This function returns a physical address, over high_memory,
-	which corresponds to an area of at least "kilobytes" kilobytes.
-	The area will be owned by the module calling the function.
-	The returned address can be passed to device boards, to instruct
-	their DMA controllers, via phys_to_bus(). The address can be used
-	by C code after vremap()/ioremap(). The "priority" argument should
-	be GFP_KERNEL or GFP_ATOMIC, according to the context of the
-	caller; it is used to call kmalloc(), as the allocator must keep
-	track of any region it gives away. In case of error the function
-	returns 0, and the caller is expected to issue a -ENOMEM error.
-
-
-   void allocator_free_dma (unsigned long address);
-
-	This function is the reverse of the previous one. If a driver
-	doesn't free the DMA memory it allocated, the allocator will
-	consider such memory as busy. Note, however, that
-	allocator_cleanup() calls kfree() on every region it reclaimed,
-	so that a driver with the allocator linked in can avoid calling
-	allocator_free_dma() at unload time.

-  -------------------------------------------------------------------
-  02-Aug-2002 NJC         allocator now steps in 1MB increments, rather
-			  than doubling its size each time.
-			  Also, allocator_init(u32 *) now returns
-			  (in the first arg) the size of the free
-			  space.  This is no longer consistent with
-			  using the allocator as a module, and some changes
-			  may be necessary for that purpose.  This was
-			  designed to work with the DT3155 driver, in
-			  stand alone mode only!!!
-  26-Oct-2009 SS	  Port to 2.6.30 kernel.

--- Changes --
-
-  Date     Programmer	Description of changes made
-  -------------------------------------------------------------------
-  03-Jul-2000 JML       n/a
-  10-Oct-2001 SS        port to 2.4 kernel
-  02-Apr-2002 SS        Mods to use allocator as a standalone module;
-                        Merged John Roll's changes (john@cfa.harvard.edu)
-                        to make work with multiple boards.
-  02-Jul-2002 SS        Merged James Rose's chages (rosejr@purdue.edu) to:
-                         * fix successive interrupt-driven captures
-                         * add select/poll support.
-  10-Jul-2002 GCS       Add error check when ndevices > MAXBOARDS.
-  02-Aug-2002 GCS       Fix field mode so that odd (lower) field is stored
-                        in lower half of buffer.
-  05-Aug-2005 SS        port to 2.6 kernel.
-  26-Oct-2009 SS	port to 2.6.30 kernel.
-
--- Notes --
-
-** appended "mem=124" in lilo.conf to allow for 4megs free on my 128meg system.
- * using allocator.c and allocator.h from o'reilly book (alessandro rubini)
-    ftp://ftp.systemy.it/pub/develop (see README.allocator)
-
- + might want to get rid of MAXboards for allocating initial buffer.
-    confusing and not necessary
-
- + in cleanup_module the MOD_IN_USE looks like it is check after it should
-
- * GFP_DMA should not be set with a PCI system (pg 291)
-
- - NJC why are only two buffers allowed? (see isr, approx line 358)

-  Date       Programmer  Description of changes made
-  -------------------------------------------------------------------
-  03-Jul-2000 JML       n/a
-  02-Apr-2002 SS        Mods to make work with separate allocator
-			module; Merged John Roll's mods to make work with
-			multiple boards.
-  10-Jul-2002 GCS       Complete rewrite of setup_buffers to disallow
-			buffers which span a 4MB boundary.
-  24-Jul-2002 SS        GPL licence.
-  30-Jul-2002 NJC       Added support for buffer loop.
-  31-Jul-2002 NJC       Complete rewrite of buffer management
-  02-Aug-2002 NJC       Including slab.h instead of malloc.h (no warning).
-			Also, allocator_init() now returns allocator_max
-			so cleaned up allocate_buffers() accordingly.
-  08-Aug-2005 SS        port to 2.6 kernel.

+    *  EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
+       1, 2, 3, 4 and an unlabelled input cable for a microphone.
+
+
+BUILD OPTIONS AND DEPENDENCIES
+------------------------------
+
+If the parameter EASYCAP_IS_VIDEODEV_CLIENT is undefined during compilation
+the built module is entirely independent of the videodev module, and when
+the EasyCAP is physically plugged into a USB port the special files
+/dev/easycap0 and /dev/easysnd1 are created as video and sound sources
+respectively.
+
+If the parameter EASYCAP_IS_VIDEODEV_CLIENT is defined during compilation
+the built easycap module is configured to register with the videodev module,
+in which case the special files created when the EasyCAP is plugged in are
+/dev/video0 and /dev/easysnd0.  Use of the easycap module as a client of
+the videodev module has received very little testing as of June 2010.
+
+
+KNOWN BUILD PROBLEMS
+--------------------
+
+(1) Recent gcc versions may generate the message:
+
+     warning: the frame size of .... bytes is larger than 1024 bytes
+
+This warning can be suppressed by specifying in the Makefile:
+
+     EXTRA_CFLAGS += -Wframe-larger-than=8192
+
+but it would be preferable to remove the cause of the warning.
+
+
+KNOWN RUNTIME ISSUES
+--------------------
+
+(1) Randomly (maybe 5 to 10% of occasions) the driver fails to produce any
+output at start-up.  Closing mplayer (or whatever the user program is) and
+restarting it restores normal performance without any other remedial action
+being necessary.  The reason for this is not known.
+
+(2) Intentionally, this driver will not stream material which is unambiguously
+identified by the hardware as copy-protected.  The video output will freeze
+within about a minute when this situation arises.
+
+(3) The controls for luminance, contrast, saturation, hue and volume may not
+always work properly.
+
+(4) Reduced-resolution S-Video seems to suffer from moire artefacts.  No
+attempt has yet been made to rememdy this.
+
+
+SUPPORTED TV STANDARDS AND RESOLUTIONS
+--------------------------------------
+
+The following TV standards are natively supported by the hardware and are
+usable as (for example) the "norm=" parameter in the mplayer command:
+
+    PAL_BGHIN,    NTSC_N_443,
+    PAL_Nc,       NTSC_N,
+    SECAM,        NTSC_M,        NTSC_M_JP,
+    PAL_60,       NTSC_443,
+    PAL_M.
+
+The available picture sizes are:
+
+     at 25 frames per second:   720x576, 704x576, 640x480, 360x288, 320x240;
+     at 30 frames per second:   720x480, 640x480, 360x240, 320x240;
+
+
+WHAT'S TESTED AND WHAT'S NOT
+----------------------------
+
+This driver is known to work with mplayer, mencoder, tvtime and sufficiently
+recent versions of vlc.  An interface to ffmpeg is implemented, but serious
+audio-video synchronization problems remain.
+
+The driver is designed to support all the TV standards accepted by the
+hardware, but as yet it has actually been tested on only a few of these.
+
+I have been unable to test and calibrate the S-video input myself because I
+do not possess any equipment with S-video output.
+
+This driver does not understand the V4L1 IOCTL commands, so programs such
+as camorama are not compatible.  There are reports that the driver does
+work with sufficiently recent (V4L2) versions of zoneminder, but I have not
+attempted to confirm this myself.
+
+
+UDEV RULES
+----------
+
+In order that the special files /dev/easycap0 and /dev/easysnd1 are created
+with conveniently relaxed permissions when the EasyCAP is plugged in, a file
+is preferably to be provided in directory /etc/udev/rules.d with content:
+
+ACTION!="add|change", GOTO="easycap_rules_end"
+ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
+	MODE="0666", OWNER="root", GROUP="root"
+LABEL="easycap_rules_end"
+
+
+ACKNOWLEGEMENTS AND REFERENCES
+------------------------------
+This driver makes use of information contained in the Syntek Semicon DC-1125
+Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
+by Nicolas Vivien.  Particularly useful has been a patch to the latter driver
+provided by Ivor Hewitt in January 2009.  The NTSC implementation is taken
+from the work of Ben Trask.

+ * lirc_igorplugusb - USB remote support for LIRC
+ *
+ * Supports the standard homebrew IgorPlugUSB receiver with Igor's firmware.
+ * See http://www.cesko.host.sk/IgorPlugUSB/IgorPlug-USB%20(AVR)_eng.htm
+ *
+ * The device can only record bursts of up to 36 pulses/spaces.
+ * Works fine with RC5. Longer commands lead to device buffer overrun.
+ * (Maybe a better firmware or a microcontroller with more ram can help?)

+ * The ITE8709 device seems to be the combination of IT8512 superIO chip and
+ * a specific firmware running on the IT8512's embedded micro-controller.
+ * In addition of the embedded micro-controller, the IT8512 chip contains a
+ * CIR module and several other modules. A few modules are directly accessible
+ * by the host CPU, but most of them are only accessible by the
+ * micro-controller. The CIR module is only accessible by the micro-controller.
+ * The battery-backed SRAM module is accessible by the host CPU and the
+ * micro-controller. So one of the MC's firmware role is to act as a bridge
+ * between the host CPU and the CIR module. The firmware implements a kind of
+ * communication protocol using the SRAM module as a shared memory. The IT8512
+ * specification is publicly available on ITE's web site, but the communication
+ * protocol is not, so it was reverse-engineered.

+ * Steve's changes to improve transmission fidelity:
+ *   - for systems with the rdtsc instruction and the clock counter, a
+ *     send_pule that times the pulses directly using the counter.
+ *     This means that the LIRC_SERIAL_TRANSMITTER_LATENCY fudge is
+ *     not needed. Measurement shows very stable waveform, even where
+ *     PCI activity slows the access to the UART, which trips up other
+ *     versions.
+ *   - For other system, non-integer-microsecond pulse/space lengths,
+ *     done using fixed point binary. So, much more accurate carrier
+ *     frequency.
+ *   - fine tuned transmitter latency, taking advantage of fractional
+ *     microseconds in previous change
+ *   - Fixed bug in the way transmitter latency was accounted for by
+ *     tuning the pulse lengths down - the send_pulse routine ignored
+ *     this overhead as it timed the overall pulse length - so the
+ *     pulse frequency was right but overall pulse length was too
+ *     long. Fixed by accounting for latency on each pulse/space
+ *     iteration.

+ * consistent timing behaviour to user space applications. Without the
+ * delay buffer an ugly hack would be required in lircd, which can
+ * cause sluggish signal decoding in certain situations.

 really have people help them out on the "clean" ar9170 driver that can
 be found at the linux-wireless developer site.
 
-But, if you wish to clean up this driver instead, here's a short list of
-things that need to be done to get it into a more mergable shape:
-
-TODO:
-	- checkpatch.pl cleanups
-	- sparse cleanups
-	- port to in-kernel 80211 stack
-	- review by the wireless developer community
-
-Please send any patches to Greg Kroah-Hartman <greg@kroah.com> and
-Luis Rodriguez <Luis.Rodriguez@Atheros.com> and the
-otus-devel@lists.madwifi-project.org mailing list.
+This driver is unmaintained and its only purpose is as a
+source of documentation for developers working on ar9170 and carl9170.
+Once carl9170 gets 11n support and merged upstream then this driver
+can be removed.

-ramzswap: Compressed RAM based swap device
--------------------------------------------
-
-Project home: http://compcache.googlecode.com/
-
-* Introduction
-
-The ramzswap module creates RAM based block devices which can (only) be used as
-swap disks. Pages swapped to these devices are compressed and stored in memory
-itself. See project home for use cases, performance numbers and a lot more.
-
-Individual ramzswap devices are configured and initialized using rzscontrol
-userspace utility as shown in examples below. See rzscontrol man page for more
-details.
-
-* Usage
-
-Following shows a typical sequence of steps for using ramzswap.
-
-1) Load Modules:
-	modprobe ramzswap num_devices=4
-	This creates 4 (uninitialized) devices: /dev/ramzswap{0,1,2,3}
-	(num_devices parameter is optional. Default: 1)
-
-2) Initialize:
-	Use rzscontrol utility to configure and initialize individual
-	ramzswap devices. Example:
-	rzscontrol /dev/ramzswap2 --init # uses default value of disksize_kb
-
-	*See rzscontrol man page for more details and examples*
-
-3) Activate:
-	swapon /dev/ramzswap2 # or any other initialized ramzswap device
-
-4) Stats:
-	rzscontrol /dev/ramzswap2 --stats
-
-5) Deactivate:
-	swapoff /dev/ramzswap2
-
-6) Reset:
-	rzscontrol /dev/ramzswap2 --reset
-	(This frees all the memory allocated for this device).
-
-

- - Mailing list: linux-mm-cc at laptop dot org

-	  This driver allows other kernel drivers access to the
-	  contents of the restricted access region control registers.
-
-	  The restricted access region control registers
-	  (rar_registers) are used to pass address and
-	  locking information on restricted access regions
-	  to other drivers that use restricted access regions.
-
-	  The restricted access regions are regions of memory
-	  on the Intel MID Platform that are not accessible to
-	  the x86 processor, but are accessible to dedicated
-	  processors on board peripheral devices.
-
-	  The purpose of the restricted access regions is to
-	  protect sensitive data from compromise by unauthorized
-	  programs running on the x86 processor.

+	* encoder on/off controls
+	* mpeg cid bitrate mode (vbr/cbr)
+	* mpeg cid bitrate/bitrate-peak
+	* mpeg encode of user data
+	* mpeg decode of user data
+	* switch between 4 frames/irq to 1 when using mjpeg (and then back
+	  when not)
+	* implement a CID control for motion areas/thresholds
+	* implement CID controls for mozaic areas
+	* allow for higher level of interval (for < 1 fps)
+	* sound:
+	  - implement playback via external sound jack
+	  - implement loopback of external sound jack with incoming audio?
+	  - implement pause/resume
+	  - check into jacking sound from tx28xx chips directly (to avoid
+	    g.723/8khz limitations)

+This is a driver for NAND controller of Intel Moorestown platform.
+
+This driver is a standalone linux block device driver, it acts as if it's a normal hard disk.
+It includes three layer:
+	block layer interface - file ffsport.c
+	Flash Translation Layer (FTL) - file flash.c (implement the NAND flash Translation Layer, includs address mapping, garbage collection, wear-leveling and so on)
+	Low level layer - file lld_nand.c/lld_cdma.c/lld_emu.c (which implements actual controller hardware registers access)
+
+This driver can be build as modules or build-in.
+
+Dependency:
+This driver has dependency on IA Firmware of Intel Moorestown platform.
+It need the IA Firmware to create the block table for the first time.
+And to validate this driver code without IA Firmware, you can change the
+macro AUTO_FORMAT_FLASH from 0 to 1 in file spectraswconfig.h. Thus the
+driver will erase the whole nand flash and create a new block table.
+
+TODO:
+	- Enable Command DMA feature support
+	- lower the memory footprint
+	- Remove most of the unnecessary global variables
+	- Change all the upcase variable / functions name to lowercase
+	- Some other misc bugs
+
+Please send patches to:
+	Greg Kroah-Hartman <gregkh@suse.de>

+*               blocks gone bad over the ages. Therefore, if we have a
+*               block table in place, then use it to scan for bad blocks
+*               If not, then scan for MDF.
+*               Now, a block table will only be found if spectra was already
+*               being used. For a fresh flash, we'll go thru scanning for
+*               MDF. If spectra was being used, then there is a chance that
+*               the MDF has been corrupted. Spectra avoids writing to the
+*               first 2 bytes of the spare area to all pages in a block. This
+*               covers all known flash devices. However, since flash
+*               manufacturers have no standard of where the MDF is stored,
+*               this cannot guarantee that the MDF is protected for future

 TODO:
 
-1. A per-device/tty port context required to support multiple devices

-2. REMOVE the sysfs entry PID passing mechanism, since there should

-
-5. Step up and maintain this driver to ensure that it continues
+1. Step up and maintain this driver to ensure that it continues
 to work.  Having the hardware for this is pretty much a
 requirement.  If this does not happen, the will be removed in
 the 2.6.35 kernel release.

+
+DSP/BIOS Bridge overview
+========================
+
+DSP/BIOS Bridge is designed for platforms that contain a GPP and one or more
+attached DSPs.  The GPP is considered the master or "host" processor, and the
+attached DSPs are processing resources that can be utilized by applications
+and drivers running on the GPP.
+
+The abstraction that DSP/BIOS Bridge supplies, is a direct link between a GPP
+program and a DSP task.  This communication link is partitioned into two
+types of sub-links:  messaging (short, fixed-length packets) and data
+streaming (multiple, large buffers).  Each sub-link operates independently,
+and features in-order delivery of data, meaning that messages are delivered
+in the order they were submitted to the message link, and stream buffers are
+delivered in the order they were submitted to the stream link.
+
+In addition, a GPP client can specify what inputs and outputs a DSP task
+uses. DSP tasks typically use message objects for passing control and status
+information and stream objects for efficient streaming of real-time data.
+
+GPP Software Architecture
+=========================
+
+A GPP application communicates with its associated DSP task running on the
+DSP subsystem using the DSP/BIOS Bridge API. For example, a GPP audio
+application can use the API to pass messages to a DSP task that is managing
+data flowing from analog-to-digital converters (ADCs) to digital-to-analog
+converters (DACs).
+
+From the perspective of the GPP OS, the DSP is treated as just another
+peripheral device.   Most high level GPP OS typically support a device driver
+model, whereby applications can safely access and share a hardware peripheral
+through standard driver interfaces.  Therefore, to allow multiple GPP
+applications to share access to the DSP, the GPP side of DSP/BIOS Bridge
+implements a device driver for the DSP.
+
+Since driver interfaces are not always standard across GPP OS, and to provide
+some level of interoperability of application code using DSP/BIOS Bridge
+between GPP OS, DSP/BIOS Bridge provides a standard library of APIs which
+wrap calls into the device driver.   So, rather than calling GPP OS specific
+driver interfaces, applications (and even other device drivers) can use the
+standard API library directly.
+
+DSP Software Architecture
+=========================
+
+For DSP/BIOS, DSP/BIOS Bridge adds a device-independent streaming I/O (STRM)
+interface, a messaging interface (NODE), and a Resource Manager (RM) Server.
+The RM Server runs as a task of DSP/BIOS and is subservient to commands
+and queries from the GPP.  It executes commands to start and stop DSP signal
+processing nodes in response to GPP programs making requests through the
+(GPP-side) API.
+
+DSP tasks started by the RM Server are similar to any other DSP task with two
+important differences:  they must follow a specific task model consisting of
+three C-callable functions (node create, execute, and delete), with specific
+sets of arguments, and they have a pre-defined task environment established
+by the RM Server.
+
+Tasks started by the RM Server communicate using the STRM and NODE interfaces
+and act as servers for their corresponding GPP clients, performing signal
+processing functions as requested by messages sent by their GPP client.
+Typically, a DSP task moves data from source devices to sink devices using
+device independent I/O streams, performing application-specific processing
+and transformations on the data while it is moved.  For example, an audio
+task might perform audio decompression (ADPCM, MPEG, CELP) on data received
+from a GPP audio driver and then send the decompressed linear samples to a
+digital-to-analog converter.

+			DSP/Bridge Error Code Guide
+
+
+Success code is always taken as 0, except for one case where a success status
+different than 0 can be possible, this is when enumerating a series of dsp
+objects, if the enumeration doesn't have any more objects it is considered as a
+successful case. In this case a positive ENODATA is returned (TODO: Change to
+avoid this case).
+
+Error codes are returned as a negative 1, if an specific code is expected, it
+can be propagated to user space by reading errno symbol defined in errno.h, for
+specific details on the implementation a copy of the standard used should be
+read first.
+
+The error codes used by this driver are:
+
+[EPERM]
+    General driver failure.
+
+    According to the use case the following might apply:
+    - Device is in 'sleep/suspend' mode due to DPM.
+    - User cannot mark end of stream on an input channel.
+    - Requested operation is invalid for the node type.
+    - Invalid alignment for the node messaging buffer.
+    - The specified direction is invalid for the stream.
+    - Invalid stream mode.
+
+[ENOENT]
+    The specified object or file was not found.
+
+[ESRCH]
+    A shared memory buffer contained in a message or stream could not be mapped
+    to the GPP client process's virtual space.
+
+[EIO]
+    Driver interface I/O error.
+
+    or:
+    - Unable to plug channel ISR for configured IRQ.
+    - No free I/O request packets are available.
+
+[ENXIO]
+    Unable to find a named section in DSP executable or a non-existent memory
+    segment identifier was specified.
+
+[EBADF]
+    General error for file handling:
+
+    - Unable to open file.
+    - Unable to read file.
+    - An error occurred while parsing the DSP executable file.
+
+[ENOMEM]
+    A memory allocation failure occurred.
+
+[EACCES]
+    - Unable to read content of DCD data section; this is typically caused by
+    improperly configured nodes.
+    - Unable to decode DCD data section content; this is typically caused by
+    changes to DSP/BIOS Bridge data structures.
+    - Unable to get pointer to DCD data section; this is typically caused by
+    improperly configured UUIDs.
+    - Unable to load file containing DCD data section; this is typically
+    caused by a missing COFF file.
+    - The specified COFF file does not contain a valid node registration
+    section.
+
+[EFAULT]
+    Invalid pointer or handler.
+
+[EEXIST]
+    Attempted to create a channel manager  when one already exists.
+
+[EINVAL]
+    Invalid argument.
+
+[ESPIPE]
+    Symbol not found in the COFF file.  DSPNode_Create will return this if
+    the iAlg function table for an xDAIS socket is not found in the COFF file.
+    In this case, force the symbol to be linked into the COFF file.
+    DSPNode_Create, DSPNode_Execute, and DSPNode_Delete will return this if

+    found in the COFF file.
+
+    - No symbol table is loaded/found for this board.
+    - Unable to initialize the ZL COFF parsing module.
+
+[EPIPE]
+    I/O is currently pending.
+
+    - End of stream was already requested on this output channel.
+
+[EDOM]
+    A parameter is specified outside its valid range.
+
+[ENOSYS]
+    The indicated operation is not supported.
+
+[EIDRM]
+    During enumeration a change in the number or properties of the objects
+    has occurred.
+
+[ECHRNG]
+    Attempt to created channel manager with too many channels or channel ID out
+    of range.
+
+[EBADR]
+    The state of the specified object is incorrect for the requested operation.
+
+    - Invalid segment ID.
+
+[ENODATA]
+    Unable to retrieve resource information from the registry.
+
+    - No more registry values.
+
+[ETIME]
+    A timeout occurred before the requested operation could complete.
+
+[ENOSR]
+    A stream has been issued the maximum number of buffers allowed in the
+    stream at once; buffers must be reclaimed from the stream before any more
+    can be issued.
+
+    - No free channels are available.
+
+[EILSEQ]
+    Error occurred in a dynamic loader library function.
+
+[EISCONN]

+ * This C header file gives the layout of the data structure created by the
+ * dynamic loader to describe the set of modules loaded into the DSP.
+ *
+ * Linked List Structure:
+ * ----------------------
+ * The data structure defined here is a singly-linked list.  The list
+ * represents the set of modules which are currently loaded in the DSP memory.
+ * The first entry in the list is a header record which contains a flag
+ * representing the state of the list.  The rest of the entries in the list
+ * are module records.
+ *
+ * Global symbol  _DLModules designates the first record in the list (i.e. the
+ * header record).  This symbol must be defined in any program that wishes to
+ * use DLLview plug-in.
+ *
+ * String Representation:
+ * ----------------------
+ * The string names of the module and its sections are stored in a block of
+ * memory which follows the module record itself.  The strings are ordered:
+ * module name first, followed by section names in order from the first
+ * section to the last.  String names are tightly packed arrays of 8-bit
+ * characters (two characters per 16-bit word on the C55x).  Strings are
+ * zero-byte-terminated.
+ *
+ * Creating and updating the list:
+ * -------------------------------
+ * Upon loading a new module into the DSP memory the dynamic loader inserts a
+ * new module record as the first module record in the list.  The fields of
+ * this module record are initialized to reflect the properties of the module.
+ * The dynamic loader does NOT increment the flag/counter in the list's header
+ * record.
+ *
+ * Upon unloading a module from the DSP memory the dynamic loader removes the
+ * module's record from this list.  The dynamic loader also increments the
+ * flag/counter in the list's header record to indicate that the list has been
+ * changed.

+ *  Notes:
+ *
+ *  Memory blocks are allocated from the end of the first free memory
+ *  block large enough to satisfy the request.  Alignment requirements
+ *  are satisfied by "sliding" the block forward until its base satisfies
+ *  the alignment specification; if this is not possible then the next
+ *  free block large enough to hold the request is tried.
+ *
+ *  Since alignment can cause the creation of a new free block - the
+ *  unused memory formed between the start of the original free block
+ *  and the start of the allocated block - the memory manager must free
+ *  this memory to prevent a memory leak.
+ *
+ *  Overlay memory is managed by reserving through rmm_alloc, and freeing
+ *  it through rmm_free. The memory manager prevents DSP code/data that is
+ *  overlayed from being overwritten as long as the memory it runs at has
+ *  been allocated, and not yet freed.

+zram: Compressed RAM based block devices
+----------------------------------------
+
+Project home: http://compcache.googlecode.com/
+
+* Introduction
+
+The zram module creates RAM based block devices: /dev/ramX (X = 0, 1, ...).
+Pages written to these disks are compressed and stored in memory itself.
+These disks allow very fast I/O and compression provides good amounts of
+memory savings.
+
+See project home for use cases, performance numbers and a lot more.
+
+Individual zram devices are configured and initialized using zramconfig
+userspace utility as shown in examples below. See zramconfig man page for
+more details.
+
+* Usage
+
+Following shows a typical sequence of steps for using zram.
+
+1) Load Modules:
+	modprobe zram num_devices=4
+	This creates 4 (uninitialized) devices: /dev/zram{0,1,2,3}
+	(num_devices parameter is optional. Default: 1)
+
+2) Initialize:
+	Use zramconfig utility to configure and initialize individual
+	zram devices. For example:
+	zramconfig /dev/zram0 --init # uses default value of disksize_kb
+	zramconfig /dev/zram1 --disksize_kb=102400 # 100MB /dev/zram1
+
+	*See zramconfig man page for more details and examples*
+
+3) Activate:
+	mkswap /dev/zram0
+	swapon /dev/zram0
+
+	mkfs.ext4 /dev/zram1
+	mount /dev/zram1 /tmp
+
+4) Stats:
+	zramconfig /dev/zram0 --stats
+	zramconfig /dev/zram1 --stats
+
+5) Deactivate:
+	swapoff /dev/zram0
+	umount /dev/zram1
+
+6) Reset:
+	zramconfig /dev/zram0 --reset
+	zramconfig /dev/zram1 --reset
+	(This frees memory allocated for the given device).
+

+ - Mailing list: linux-mm-cc at laptop dot org

+ * The OCTEON watchdog has a maximum timeout of 2^32 * io_clock.
+ * For most systems this is less than 10 seconds, so to allow for
+ * software to request longer watchdog heartbeats, we maintain software
+ * counters to count multiples of the base rate.  If the system locks
+ * up in such a manner that we can not run the software counters, the
+ * only result is a watchdog reset sooner than was requested.  But
+ * that is OK, because in this case userspace would likely not be able
+ * to do anything anyhow.
+ *
+ * The hardware watchdog interval we call the period.  The OCTEON
+ * watchdog goes through several stages, after the first period an
+ * irq is asserted, then if it is not reset, after the next period NMI
+ * is asserted, then after an additional period a chip wide soft reset.
+ * So for the software counters, we reset watchdog after each period
+ * and decrement the counter.  But for the last two periods we need to

+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ *    be lost, thus blocking readers forever.
+ *    If this synchronization point is not a mutex, but a spinlock or
+ *    spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ *    are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ *    pure reads. But if they have to fetch many values, it's better to not allow
+ *    preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ *    (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ *     read partial values)
+ *
+ * 7) For softirq uses, readers can use u64_stats_fetch_begin_bh() and
+ *    u64_stats_fetch_retry_bh() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])
+ *
+ *   spin_lock_bh(...) or other synchronization to get exclusive access
+ *   ...

+ *   stats->bytes64 += len; // non atomic operation
+ *   stats->packets64++;    // non atomic operation
+ *   u64_stats_update_end(&stats->syncp);

+ * If a wakeup event occurs when the system is in a sleep state, it simply is

+ * state occurs when it is undergoing a transition to that sleep state, the
+ * transition should be aborted.  Moreover, if such an event occurs when the

+ * There is no strict promise about the base, although it tends to start
+ * at 0 on boot (but people really shouldn't rely on that).

+ * sched_clock_cpu(i) -- must be used with local IRQs disabled (implied by NMI)
+ * local_clock()      -- is cpu_clock() on the current cpu.
+ *
+ * How:
+ *
+ * The implementation either uses sched_clock() when
+ * !CONFIG_HAVE_UNSTABLE_SCHED_CLOCK, which means in that case the
+ * sched_clock() is assumed to provide these properties (mostly it means
+ * the architecture provides a globally synchronized highres time source).
+ *
+ * Otherwise it tries to create a semi stable clock from a mixture of other
+ * clocks, including:
+ *
+ *  - GTOD (clock monotomic)
  *  - sched_clock()
  *  - explicit idle events
  *
- * We use gtod as base and the unstable clock deltas. The deltas are filtered,
- * making it monotonic and keeping it within an expected window.
+ * We use GTOD as base and use sched_clock() deltas to improve resolution. The
+ * deltas are filtered to provide monotonicity and keeping it within an
+ * expected window.
  *
  * Furthermore, explicit sleep and wakeup hooks allow us to account for time
  * that is otherwise invisible (TSC gets stopped).
  *
- * The clock: sched_clock_cpu() is monotonic per cpu, and should be somewhat
- * consistent between cpus (never more than 2 jiffies difference).
+ *
+ * Notes:
+ *
+ * The !IRQ-safetly of sched_clock() and sched_clock_cpu() comes from things
+ * like cpufreq interrupts that can change the base clock (TSC) multiplier
+ * and cause funny jumps in time -- although the filtering provided by
+ * sched_clock_cpu() should mitigate serious artifacts we cannot rely on it
+ * in general since for !CONFIG_HAVE_UNSTABLE_SCHED_CLOCK we fully rely on

+ * CPU hotplug.
+ *
+ * There are two challenges in supporting CPU hotplug.  Firstly, there
+ * are a lot of assumptions on strong associations among work, cwq and
+ * gcwq which make migrating pending and scheduled works very
+ * difficult to implement without impacting hot paths.  Secondly,
+ * gcwqs serve mix of short, long and very long running works making
+ * blocked draining impractical.
+ *
+ * This is solved by allowing a gcwq to be detached from CPU, running
+ * it with unbound (rogue) workers and allowing it to be reattached
+ * later if the cpu comes back online.  A separate thread is created
+ * to govern a gcwq in such state and is called the trustee of the
+ * gcwq.
+ *
+ * Trustee states and their descriptions.
+ *
+ * START	Command state used on startup.  On CPU_DOWN_PREPARE, a
+ *		new trustee is started with this state.
+ *
+ * IN_CHARGE	Once started, trustee will enter this state after
+ *		assuming the manager role and making all existing
+ *		workers rogue.  DOWN_PREPARE waits for trustee to
+ *		enter this state.  After reaching IN_CHARGE, trustee
+ *		tries to execute the pending worklist until it's empty
+ *		and the state is set to BUTCHER, or the state is set
+ *		to RELEASE.
+ *
+ * BUTCHER	Command state which is set by the cpu callback after
+ *		the cpu has went down.  Once this state is set trustee
+ *		knows that there will be no new works on the worklist
+ *		and once the worklist is empty it can proceed to
+ *		killing idle workers.
+ *
+ * RELEASE	Command state which is set by the cpu callback if the
+ *		cpu down has been canceled or it has come online
+ *		again.  After recognizing this state, trustee stops
+ *		trying to drain or butcher and clears ROGUE, rebinds
+ *		all remaining workers back to the cpu and releases
+ *		manager role.
+ *
+ * DONE		Trustee will enter this state after BUTCHER or RELEASE
+ *		is complete.
+ *

+# Configuration for DNS Resolver

+config DNS_RESOLVER
+	tristate "DNS Resolver support"
+	depends on NET && KEYS
+	help
+	  Saying Y here will include support for the DNS Resolver key type
+	  which can be used to make upcalls to perform DNS lookups in
+	  userspace.
+
+	  DNS Resolver is used to query DNS server for information.  Examples
+	  being resolving a UNC hostname element to an IP address for CIFS or
+	  performing a DNS query for AFSDB records so that AFS can locate a
+	  cell's volume location database servers.
+
+	  DNS Resolver is used by the CIFS and AFS modules, and would support
+	  SMB2 later.  DNS Resolver is supported by the userspace upcall
+	  helper "/sbin/dns.resolver" via /etc/request-key.conf.
+
+	  See <file:Documentation/networking/dns_resolver.txt> for further
+	  information.
+
+	  To compile this as a module, choose M here: the module will be called
+	  dnsresolver.
+
+	  If unsure, say N.

  *
  * Aggregation on the TX side requires setting the hardware flag
- * %IEEE80211_HW_AMPDU_AGGREGATION as well as, if present, the @ampdu_queues
- * hardware parameter to the number of hardware AMPDU queues. If there are no
- * hardware queues then the driver will (currently) have to do all frame
- * buffering.
+ * %IEEE80211_HW_AMPDU_AGGREGATION. The driver will then be handed
+ * packets with a flag indicating A-MPDU aggregation. The driver
+ * or device is responsible for actually aggregating the frames,
+ * as well as deciding how many and which to aggregate.
  *
- * When TX aggregation is started by some subsystem (usually the rate control
- * algorithm would be appropriate) by calling the
- * ieee80211_start_tx_ba_session() function, the driver will be notified via
- * its @ampdu_action function, with the %IEEE80211_AMPDU_TX_START action.

+ * ieee80211_start_tx_ba_session() function, the driver will be
+ * notified via its @ampdu_action function, with the
+ * %IEEE80211_AMPDU_TX_START action.
  *
  * In response to that, the driver is later required to call the
- * ieee80211_start_tx_ba_cb() (or ieee80211_start_tx_ba_cb_irqsafe())
- * function, which will start the aggregation session.
+ * ieee80211_start_tx_ba_cb_irqsafe() function, which will really
+ * start the aggregation session after the peer has also responded.
+ * If the peer responds negatively, the session will be stopped
+ * again right away. Note that it is possible for the aggregation
+ * session to be stopped before the driver has indicated that it
+ * is done setting it up, in which case it must not indicate the
+ * setup completion.
  *
- * Similarly, when the aggregation session is stopped by
- * ieee80211_stop_tx_ba_session(), the driver's @ampdu_action function will
- * be called with the action %IEEE80211_AMPDU_TX_STOP. In this case, the
- * call must not fail, and the driver must later call ieee80211_stop_tx_ba_cb()
- * (or ieee80211_stop_tx_ba_cb_irqsafe()).
+ * Also note that, since we also need to wait for a response from
+ * the peer, the driver is notified of the completion of the
+ * handshake by the %IEEE80211_AMPDU_TX_OPERATIONAL action to the
+ * @ampdu_action callback.

+ * AppArmor policy is based around profiles, which contain the rules a
+ * task is confined by.  Every task in the system has a profile attached
+ * to it determined either by matching "unconfined" tasks against the
+ * visible set of profiles or by following a profiles attachment rules.
+ *
+ * Each profile exists in a profile namespace which is a container of
+ * visible profiles.  Each namespace contains a special "unconfined" profile,
+ * which doesn't enforce any confinement on a task beyond DAC.
+ *
+ * Namespace and profile names can be written together in either
+ * of two syntaxes.
+ *	:namespace:profile - used by kernel interfaces for easy detection
+ *	namespace://profile - used by policy
+ *
+ * Profile names can not start with : or @ or ^ and may not contain \0
+ *
+ * Reserved profile names
+ *	unconfined - special automatically generated unconfined profile
+ *	inherit - special name to indicate profile inheritance
+ *	null-XXXX-YYYY - special automatically generated learning profiles
+ *
+ * Namespace names may not start with / or @ and may not contain \0 or :
+ * Reserved namespace names
+ *	user-XXXX - user defined profiles
+ *
+ * a // in a profile or namespace name indicates a hierarchical name with the
+ * name before the // being the parent and the name after the child.
+ *
+ * Profile and namespace hierarchies serve two different but similar purposes.
+ * The namespace contains the set of visible profiles that are considered
+ * for attachment.  The hierarchy of namespaces allows for virtualizing
+ * the namespace so that for example a chroot can have its own set of profiles
+ * which may define some local user namespaces.
+ * The profile hierarchy severs two distinct purposes,
+ * -  it allows for sub profiles or hats, which allows an application to run
+ *    subprograms under its own profile with different restriction than it
+ *    self, and not have it use the system profile.
+ *    eg. if a mail program starts an editor, the policy might make the
+ *        restrictions tighter on the editor tighter than the mail program,
+ *        and definitely different than general editor restrictions
+ * - it allows for binary hierarchy of profiles, so that execution history
+ *   is preserved.  This feature isn't exploited by AppArmor reference policy
+ *   but is allowed.  NOTE: this is currently suboptimal because profile
+ *   aliasing is not currently implemented so that a profile for each
+ *   level must be defined.
+ *   eg. /bin/bash///bin/ls as a name would indicate /bin/ls was started
+ *       from /bin/bash
+ *
+ *   A profile or namespace name that can contain one or more // separators
+ *   is referred to as an hname (hierarchical).
+ *   eg.  /bin/bash//bin/ls
+ *
+ *   An fqname is a name that may contain both namespace and profile hnames.
+ *   eg. :ns:/bin/bash//bin/ls
+ *
+ * NOTES:
+ *   - locking of profile lists is currently fairly coarse.  All profile
+ *     lists within a namespace use the namespace lock.
+ * FIXME: move profile lists to using rcu_lists

-/*
- * tomoyo_alias_list is used for holding list of symlink's pathnames which are
- * allowed to be passed to an execve() request. Normally, the domainname which
- * the current process will belong to after execve() succeeds is calculated
- * using dereferenced pathnames. But some programs behave differently depending
- * on the name passed to argv[0]. For busybox, calculating domainname using
- * dereferenced pathnames will cause all programs in the busybox to belong to
- * the same domain. Thus, TOMOYO provides a way to allow use of symlink's
- * pathname for checking execve()'s permission and calculating domainname which
- * the current process will belong to after execve() succeeds.
- *
- * An entry is added by
- *
- * # echo 'alias /bin/busybox /bin/cat' > \
- *                            /sys/kernel/security/tomoyo/exception_policy
- *
- * and is deleted by
- *
- * # echo 'delete alias /bin/busybox /bin/cat' > \
- *                            /sys/kernel/security/tomoyo/exception_policy
- *
- * and all entries are retrieved by
- *
- * # grep ^alias /sys/kernel/security/tomoyo/exception_policy
- *
- * In the example above, if /bin/cat is a symlink to /bin/busybox and execution
- * of /bin/cat is requested, permission is checked for /bin/cat rather than
- * /bin/busybox and domainname which the current process will belong to after
- * execve() succeeds is calculated using /bin/cat rather than /bin/busybox .
