2008-11-01saner FASYNC handling on file closeAl Viro
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

2008-10-30sgi-xp: only build for ia64-sn2 when CONFIG_IA64_GENERIC specifiedDean Nelson
For the time being build for ia64-sn2 alone when CONFIG_IA64_GENERIC is specified. This eliminates a dependency of the XP/XPC drivers on having the GRU driver insmod'd in order to insmod them, when running on an ia64-sn2 system. On such a system the GRU driver serves no useful purpose.

2008-10-22ACPI: thinkpad-acpi: attempt to preserve fan state on resumeHenrique de Moraes Holschuh
Attempt to preserve fan state across sleep and hibernation if the fan control mode is enabled. For safety reasons, only the PWM OFF (fan at 100%) or maximum closed-loop level (level 7) are preserved. If the fan state was set to anything else, it will not be restored. Also, should the fan be at PWM OFF mode at resume, it will be left at that state (but this is extremely unlikely, no ThinkPad firmware was ever reported to do this). For reference, the known states used for fan control upon resume by the firmware are either "auto" or "level 7" depending on whether the laptop wakes due to normal conditions or a thermal emergency.

2008-10-22ACPI: replace AE_BAD_ADDRESS exception code with AE_ERRORLin Ming
The AE_BAD_ADDRESS exception code is now unused in ACPICA. For linux, it's only used at wmi.c and acer-wmi.c. I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code has no special meaning. The parent functions just call AE_SUCCESS() or AE_FAILURE() to check the return status.

2008-10-10fujitsu-laptop: better handling of P8010 hotkeyJonathan Woithe
This patch (mostly from Peter Gruber) improves the handling of the hotkeys for P8010 laptops by passing more accurate input events back to userspace. This is needed because the P8010 labels these buttons quite differently to earlier laptops. As part of this, a P8010-specific DMI callback check has been implemented.

2008-10-08acer-wmi: Add rfkill support for wireless and bluetoothCarlos Corbacho
This patch implements rfkill support for the wireless and bluetooth devices commonly found on Acer laptops. For now, we will always poll these devices once a second to guarantee we can catch state changes. On newer Acer laptops, it may be possible to rely on WMI events to do this instead, and experimental support for this will be added in a later patch. 3G has been deliberately left off for now, as we still have no way to detect it, (nor, AFAIK, has any Linux user tried the code) and on laptops that don't support 3G, trying to poll for the status will leave the logs full of ACPI tracebacks. The old sysfs interface for wireless and bluetooth will be removed in a later patch. (Thanks to Henrique de Moraes Holschuh and Dmitry Torokhov for reviewing this patch).

This is a driver for ACPI extras such as hotkeys and backlight brightness control on various Panasonic "Let's Note" series laptop computers. It exports the backlight via the backlight class device API, and the hotkeys as input event device. Some more esoteric items like number of installed batteries are exported via sysfs device attributes. Hotkey events also generate old-style ACPI enents through /proc/acpi/event to interoperate with current versions of acpid.

2008-09-13ia64: fix panic during `modprobe -r xpc'Robin Holt
If you are on ia64 and you modprobe xpc then modprobe -r xpc, you immediately get a panic. xpc depends on xp which depends on gru for a symbol. That symbol is only used when we are running on UV hardware. Currently, the GRU driver detects we are not on UV hardware and does no initializing. It does not do the same check when unloading. As a result, the gru driver attempts to tear down stuff that was not setup. This is a simple two-line workaround to get us through this release. Once 2.6.28 is opened, we need to rework the symbols that xp is depending on from gru so the gru driver can properly fail to load when hardware is not available.
