However ACPI handles temperature values with a single decimal place. As a consequence, some implementations use an offset of 273.1 and others use an offset of 273.2. Try to find out which one is being used, to present the most accurate and visually appealing number. Tested on a Sony Vaio PGC-GR214EP (which uses 273.1) and a Lenovo Thinkpad T60p (which uses 273.2).

This theory is supported by the fact that the bad RIP value is a vmalloc address. The immediate fix is to make this a non-init call. (A better long-term fix is of course to wait with init-section unloading until a module's async initcalls have been run, which would allow us to discard this function which is still only run once, after all. Perhaps a new async_initcall() function for the async/module API, if this is needed for other modules in the future?)

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Always Running APIC timer, CPUID_0x6_EAX_Bit2. This bit means the APIC timer continues to run even when CPU is in deep C-states. The advantage is that we can use LAPIC timer on these CPUs always, and there is no need for "slow to read and program" external timers (HPET/PIT) and the timer broadcast logic and related code in C-state entry and exit.

* / hwmon: Add Asus ATK0110 supportLuca Tettamanti2009-04-071-2/+1
|/ | | | | | | | | | | | | | | | | | | | | | | Asus boards have an ACPI interface for interacting with the hwmon (fan, temperatures, voltages) subsystem; this driver exposes the relevant information via the standard sysfs interface. There are two different ACPI interfaces: - an old one (based on RVLT/RFAN/RTMP) - a new one (GGRP/GITM) Both may be present but there a few cases (my board, sigh) where the new interface is just an empty stub; the driver defaults to the old one when both are present. The old interface has received a considerable testing, but I'm still awaiting confirmation from my tester that the new one is working as expected (hence the debug code is still enabled). Currently all the attributes are read-only, though a (partial) control should be possible with a bit more work.

* ACPI: support acpi_device_ops .notify methodsBjorn Helgaas2009-04-051-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for ACPI device driver .notify() methods. If such a method is present, Linux/ACPI installs a handler for device notifications (but not for system notifications such as Bus Check, Device Check, etc). When a device notification occurs, Linux/ACPI passes it on to the driver's .notify() method. In most cases, this removes the need for drivers to install their own handlers for device-specific notifications. For fixed hardware devices like some power and sleep buttons, there's no notification value because there's no control method to execute a Notify opcode. When a fixed hardware device generates an event, we handle it the same as a regular device notification, except we send a ACPI_FIXED_HARDWARE_EVENT value. This is outside the normal 0x0-0xff range used by Notify opcodes. Several drivers install their own handlers for system Bus Check and Device Check notifications so they can support hot-plug. This patch doesn't affect that usage. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Reviewed-by: Alex Chiang <achiang@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it.

By this way, we can do it for other objects embedded with kobject. 2,It may save several bytes for each instance of struct device.(On my omap3(32bit ARM) based box, can save 8bytes per device object) This patch also introduces dev_set|get_uevent_suppress() helpers to set and query uevent_suppress attribute in case to help kobject as private part of struct device in future.

With this patch, the caller knows if the delivery of any of the messages to the listeners have failed: 1) If it fails to deliver any message (for whatever reason), return -ENOBUFS. 2) Otherwise, if all messages were delivered OK, returns 0. 3) Otherwise, if no listeners, return -ESRCH. In the current ctnetlink code and in Netfilter in general, we can add reliable logging and connection tracking event delivery by dropping the packets whose events were not successfully delivered over Netlink. Of course, this option would be settable via /proc as this approach reduces performance (in terms of filtered connections per seconds by a stateful firewall) but providing reliable logging and event delivery (for conntrackd) in return. This patch also changes some clients of netlink_broadcast() that may report ENOBUFS errors via printk. This error handling is not of any help. Instead, the userspace daemons that are listening to those netlink messages should resync themselves with the kernel-side if they hit ENOBUFS. BTW, netlink_broadcast() clients include those that call cn_netlink_send(), nlmsg_multicast() and genlmsg_multicast() since they internally call netlink_broadcast() and return its error value.

This is the same case even for NMI structure reporting. The Processor X2APIC Affinity structure provides the association between the X2APIC ID of a logical processor and the proximity domain to which the logical processor belongs. For OSPM, Procssor IDs outside the 0-254 range are to be declared as Device() objects in the ACPI namespace.
