Johan Hedberg says:
====================
pull request: bluetooth-next 2015-03-19
This wont the last 4.1 bluetooth-next pull request, but we've piled up
enough patches in less than a week that I wanted to save you from a
single huge "last-minute" pull somewhere closer to the merge window.
The main changes are:
- Simultaneous LE & BR/EDR discovery support for HW that can do it
- Complete LE OOB pairing support
- More fine-grained mgmt-command access control (normal user can now do
harmless read-only operations).
- Added RF power amplifier support in cc2520 ieee802154 driver
- Some cleanups/fixes in ieee802154 code
Please let me know if there are any issues pulling. Thanks.

The TI CC2521 is an RF power amplifier that is designed to interface
with the CC2520. Conveniently, it directly interfaces with the CC2520
and does not require any pins to be connected to a
microcontroller/processor. Adding a CC2591 increases the CC2520's range,
which is useful for border router and other wall-powered applications.
Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs
that are connected to the CC2591 to correctly set the CC2591 into TX and
RX modes. Further, TI recommends that the CC2520_TXPOWER and
CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's
performance. These settings are covered in TI Application Note AN065.
This patch adds an optional `amplified` field to the cc2520 entry in the
device tree. If present, the CC2520 will be configured to operate with a
CC2591.
The expected pin mapping is:
CC2520 GPIO0 --> CC2591 EN
CC2520 GPIO5 --> CC2591 PAEN

Similar to port id allow netdevices to specify port names and export
the name via sysfs. Drivers can implement the netdevice operation to
assist udev in having sane default names for the devices using the
rule:
$ cat /etc/udev/rules.d/80-net-setup-link.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{phys_port_name}!="",
NAME="$attr{phys_port_name}"
Use of phys_name versus phys_id was suggested-by Jiri Pirko.

This adds a tx_maxrate attribute to the tx queue sysfs entry allowing
for max-rate limiting. Along with DCB-ETS and BQL this provides another
knob to tune queue performance. The limit units are Mbps.
By default it is disabled. To disable the rate limitation after it
has been set for a queue, it should be set to zero.

Pull networking fixes from David Miller:
1) nft_compat accidently truncates ethernet protocol to 8-bits, from
Arturo Borrero.
2) Memory leak in ip_vs_proc_conn(), from Julian Anastasov.
3) Don't allow the space required for nftables rules to exceed the
maximum value representable in the dlen field. From Patrick
McHardy.
4) bcm63xx_enet can accidently leave interrupts permanently disabled
due to errors in the NAPI polling exit logic. Fix from Nicolas
Schichan.
5) Fix OOPSes triggerable by the ping protocol module, due to missing
address family validations etc. From Lorenzo Colitti.
6) Don't use RCU locking in sleepable context in team driver, from Jiri
Pirko.
7) xen-netback miscalculates statistic offset pointers when reporting
the stats to userspace. From David Vrabel.
8) Fix a leak of up to 256 pages per VIF destroy in xen-netaback, also
from David Vrabel.
9) ip_check_defrag() cannot assume that skb_network_offset(),
particularly when it is used by the AF_PACKET fanout defrag code.
From Alexander Drozdov.
10) gianfar driver doesn't query OF node names properly when trying to
determine the number of hw queues available. Fix it to explicitly
check for OF nodes named queue-group. From Tobias Waldekranz.
11) MID field in macb driver should be 12 bits, not 16. From Punnaiah
Choudary Kalluri.
12) Fix unintentional regression in traceroute due to timestamp socket
option changes. Empty ICMP payloads should be allowed in
non-timestamp cases. From Willem de Bruijn.
13) When devices are unregistered, we have to get rid of AF_PACKET
multicast list entries that point to it via ifindex. Fix from
Francesco Ruggeri.

Fixed behaviour of get_mctrl() serial driver function as documented in:
https://www.kernel.org/doc/Documentation/serial/driver
Added device-tree properties 'dcd-override', 'dsr-override',
'cts-override', and 'ri-override' specific to the Synopsis 8250
DesignWare UART driver. Allows one to force Data Carrier Detect,
Clear To Send, and Data Set Ready signals to permanently be reported as
active. The Ring indicator can be forced to be reported as inactive.
It is possible that if modem control signalling is enabled on a port
that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the
driver can hang indefinitely waiting for the state to change. The new
DT properties allow the driver to ignore the state of these pins on
serial ports that don't support them, as recommended in the kernel
documentation.

Pull power management and ACPI fixes from Rafael Wysocki:
"These are fixes for recent regressions (ACPI resources management,
suspend-to-idle), stable-candidate fixes (ACPI backlight), fixes
related to the wakeup IRQ management changes made in v3.18, other
fixes (suspend-to-idle, cpufreq ppc driver) and a couple of cleanups
(suspend-to-idle, generic power domains, ACPI backlight).
Specifics:
- Fix ACPI resources management problems introduced by the recent
rework of the code in question (Jiang Liu) and a build issue
introduced by those changes (Joachim Nilsson).
- Fix a recent suspend-to-idle regression on systems where entering
idle states causes local timers to stop, prevent suspend-to-idle
from crashing in restricted configurations (no cpuidle driver,
cpuidle disabled etc.) and clean up the idle loop somewhat while at
it (Rafael J Wysocki).
- Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).
- Allow the ACPI backlight driver module to be loaded if ACPI is
disabled which helps the i915 driver in those configurations
(stable-candidate) and change the code to help debug unusual use
cases (Chris Wilson).
- Wakeup IRQ management changes in v3.18 caused some drivers on the
at91 platform to trigger a warning from the IRQ core related to an
unexpected combination of interrupt action handler flags. However,
on at91 a timer IRQ is shared with some other devices (including
system wakeup ones) and that leads to the unusual combination of
flags in question.
To make it possible to avoid the warning introduce a new interrupt
action handler flag (which can be used by drivers to indicate the
special case to the core) and rework the problematic at91 drivers
to use it and work as expected during system suspend/resume. From
Boris Brezillon, Rafael J Wysocki and Mark Rutland.
- Clean up the generic power domains subsystem's debugfs interface
(Kevin Hilman)"

With certain restrictions it is possible for a wakeup device to share
an IRQ with an IRQF_NO_SUSPEND user, and the warnings introduced by
commit cab303be91dc47942bc25de33dc1140123540800 are spurious. The new
IRQF_COND_SUSPEND flag allows drivers to tell the core when these
restrictions are met, allowing spurious warnings to be silenced.
This patch documents how IRQF_COND_SUSPEND is expected to be used,
updating some of the text now made invalid by its addition.

The IRQF_NO_SUSPEND flag is intended to be used for interrupts required
to be enabled during the suspend-resume cycle. This mostly consists of
IPIs and timer interrupts, potentially including chained irqchip
interrupts if these are necessary to handle timers or IPIs. If an
interrupt does not fall into one of the aforementioned categories,
requesting it with IRQF_NO_SUSPEND is likely incorrect.
Using IRQF_NO_SUSPEND does not guarantee that the interrupt can wake the
system from a suspended state. For an interrupt to be able to trigger a
wakeup, it may be necessary to program various components of the system.
In these cases it is necessary to use {enable,disabled}_irq_wake.
Unfortunately, several drivers assume that IRQF_NO_SUSPEND ensures that
an IRQ can wake up the system, and the documentation can be read
ambiguously w.r.t. this property.
This patch updates the documentation regarding IRQF_NO_SUSPEND to make
this caveat explicit, hopefully making future misuse rarer. Cleanup of
existing misuse will occur as part of later patch series.

This sysctl gives two benefits. By defaulting the table size to 0
mpls even when compiled in and enabled defaults to not forwarding
any packets. This prevents unpleasant surprises for users.
The other benefit is that as mpls labels are allocated locally a dense
table a small dense label table may be used which saves memory and
is extremely simple and efficient to implement.
This sysctl allows userspace to choose the restrictions on the label
table size userspace applications need to cope with.

The memcg control knobs indicate the highest possible value using the
symbolic name "infinity", which is long and awkward to type.
Switch to the string "max", which is just as descriptive but shorter and
sweeter.
This changes a user interface, so do it before the release and before
the development flag is dropped from the default hierarchy.

We (the Ocfs2 project) recently moved the location of our ocfs2-tools
git tree and project web page. The pertinent discussion can be seen
here:
https://oss.oracle.com/pipermail/ocfs2-devel/2015-February/010579.html
The following patch updates the Ocfs2 documentation in MAINTAINERS,
ocfs2.txt, and dlmfs.txt. I added our new official web page, changed
the location of our tools git tree and removed the link to Joel's
ancient kernel git tree - Andrew has handled our patches for a while
now.

- a number of cleanups.
- preliminary support for Cavium's Octeon 3 SOCs which feature up to
48 MIPS64 R3 cores with FPU and hardware virtualization.
- support for MIPS R6 processors.
Revision 6 of the MIPS architecture is a major revision of the MIPS
architecture which does away with many of original sins of the
architecture such as branch delay slots. This and other changes in
R6 require major changes throughout the entire MIPS core
architecture code and make up for the lion share of this pull
request.
- finally some preparatory work for eXtendend Physical Address

space on 32 bit processors"

Make it possible to disable offloading writes by setting the optional
'submit_from_crypt_cpus' table argument.
There are some situations where offloading write bios from the
encryption threads to a single thread degrades performance
significantly.
The default is to offload write bios to the same thread because it
benefits CFQ to have writes submitted using the same IO context.

Use unbound workqueue by default so that work is automatically balanced

same cpu that IO was submitted on can still be enabled by setting the
optional 'same_cpu_crypt' table argument.

clock-frequency property is meant to control the bus frequency for i2c bus
drivers, but it was incorrectly used to specify i2c controller input clock
frequency.
Introduce new attribute, opencores,ip-clock-frequency, that specifies i2c
controller clock frequency and make clock-frequency attribute compatible
with other i2c drivers. Maintain backwards compatibility in case
opencores,ip-clock-frequency attribute is missing.

Add i2c-mux-idle-disconnect device tree property to PCA954x mux driver. The new
property forces the multiplexer to disconnect child buses in idle state. This is
used, for example, when there are several multiplexers on the same bus and the
devices on the underlying buses might have same I2C addresses.

On Rockchip I2C the controller drops SDA low slightly too soon to meet
the "repeated start" requirements.
>From my own experimentation over a number of rates:
- controller appears to drop SDA at .875x (7/8) programmed clk high.
- controller appears to keep SCL high for 2x programmed clk high.
The first rule isn't enough to meet tSU;STA requirements in
Standard-mode on the system I tested on. The second rule is probably
enough to meet tHD;STA requirements in nearly all cases (especially
after accounting for the first), but it doesn't hurt to account for it
anyway just in case.
Even though the repeated start requirement only need to be accounted
for during a small part of the transfer, we'll adjust the timings for
the whole transfer to meet it. I believe that adjusting the timings
in just the right place to switch things up for repeated start would
require several extra interrupts and that doesn't seem terribly worth
it.
With this change and worst case rise/fall times, I see 100kHz i2c
going to ~85kHz. With slightly optimized rise/fall (800ns / 50ns) I
see i2c going to ~89kHz. Fast-mode isn't affected much because
tSU;STA is shorter relative to tHD;STA there.
As part of this change we needed to account for the SDA falling time.
The specification indicates that this should be the same, but we'll
follow Designware's lead and add a binding. Note that we deviate from
Designware and assign the default SDA falling time to be the same as
the SCL falling time, which is incredibly likely.

The number of clock cycles to be written into the CLKDIV register
that determines the I2C clk high phase includes the rise time.
So to meet the timing requirements defined in the I2C specification
which defines the minimal time SCL has to be high, the rise time
has to taken into account. The same applies to the low phase with
falling time.
In my test on RK3288-Pink2 board, which is not an upstream board yet,
if external pull-up resistor is 4.7K, rise_ns is about 700ns.
So the measured high_ns is about 3900ns, which is less than 4000ns
(the minimum high_ns in I2C specification for Standard-mode).
To fix this bug min_low_ns should include fall time and min_high_ns
should include rise time.
This patch merged the patch from chromium project which can get the
rise and fall times for signals from the device tree. This allows us
to more accurately calculate timings. see:
