The freezer currently attempts to distinguish kernel threads from user space tasks by checking if their mm pointer is unset and it does not send fake signals to kernel threads. However, there are kernel threads, mostly related to networking, that behave like user space tasks and may want to be sent a fake signal to be frozen. Introduce the new process flag PF_FREEZER_NOSIG that will be set by default for all kernel threads and make the freezer only send fake signals to the tasks having PF_FREEZER_NOSIG unset. Provide the set_freezable_with_signal() function to be called by the kernel threads that want to be sent a fake signal for freezing. This patch should not change the freezer's observable behavior.

Get rid of a superfluous acpi_pm_device_sleep_state() parameter. The only legitimate value of that parameter must be derived from the first parameter, which is what all the callers already do. (However, this does not address the fact that ACPI still doesn't set up those flags.)

Add a debugfs file for showing the full results of the method we use to detect devices on WMID laptops. This should be useful in the case that a Linux user gets an Acer laptop with 3G support (and/ or people who enjoy ripping their wireless cards out) so we can get some feedback on how this value changes in these cases. (At the moment, we always enable the wireless and 3G control. In the case of the former, this is fairly safe. In the case of the latter though, trying to toggle this device if it doesn't exist on a laptop causes ACPI warnings/ errors). To summarise: If you have an Acer laptop with a built in 3G card, please report back the value from this file.

http://bugzilla.kernel.org/show_bug.cgi?id=9704 When echo some invalid values to /proc/acpi/processor/*/throttling, there isn't any error info returned, on the contray, it sets throttling value to some T* successfully, obviously, this is incorrect, a correct way should be to let it fail and return error info. This patch fixed the aforementioned issue, it also enables /proc/acpi/processor/*/throttling to accept such values as 't0' and 'T0', it also strictly limits /proc/acpi/processor/*/throttling only to accept "*", "t*" and "T*", "*" is the throttling state value the processor can support, current, it is 0 - 7.

Under /proc/acpi, there is a fan control interface, a user can set 0 or 3 to /proc/acpi/fan/*/state, 0 denotes D0 state, 3 denotes D3 state, but in current implementation, a user can set a fan to D1 state by any char excluding '1', '2' and '3'. For example: [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: on [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: on Obviously, such inputs as "" and "xxxxx" are invalid for fan state.

Add additional capabilities to the Fujitsu-laptop driver. * Brightness hotkey actions are sent to userspace. This can be disabled using a module parameter if it causes issues with models which handle these keys transparently in the BIOS. * Actions of additional hotkeys found on some Fujitsu models (eg: the suspend key and the dedicated "power on passphrase" keys) are broadcast to userspace. * An alternative brightness control method used by some Fujitsu models (for example, the S6410) is now supported, enabling software brightness controls on models using this method. * DMI-based module aliases are configured for the S6410 and S7020. * The current LCD brightness after booting should now be reflected in the standard backlight interface sysfs file (previously it was always set to 0). The platform brightness sysfs interface has always been fine. Thanks go to Peter Gruber who provided a significant portion of this code and tested various iterations of the patch on his S6410.

"/sys/devices/LNXSYSTM:00/.../eject" is used to evaluate _EJx method and eject a device in user space. But system hangs when poking the "eject" file because that the device hot-removal code invoke the driver .remove method which will try to remove the "eject" file as a result. Queues the hot-removal function for deferred execution in this patch. http://bugzilla.kernel.org/show_bug.cgi?id=9772Signed-off-by: NZhang Rui <rui.zhang@intel.com> Signed-off-by: NLen Brown <len.brown@intel.com> Signed-off-by: NAndi Kleen <ak@linux.intel.com>

Crosscompiling on a Fedora 9 machine running gcc 4.3.0 as its host compiler and gcc 3.4.6 for the mips-linux target results in the following build error: $ make malta_defconfig $ make cc1: error: unrecognized command line option "-fno-stack-protector" scripts/kconfig/conf -s arch/mips/Kconfig cc1: error: unrecognized command line option "-fno-stack-protector" The arch Makefile is included too late so the host compiler is feature tested, not the crosscompiler as intended and thus the Makefile applies adds -fno-stack-protector to crosscompiler's flags which fails for gcc 3.4.6. The bug was introduced by e06b8b98 in 2.6.25; 35bb5b1e did add more flags testing before the arch Makefile inclusion.
