* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

| | | | | | | | | | | | The i8042 driver fails detection of the AUX port with some chips, because they apparently do not change the I8042_CTR_AUXDIS bit immediately. This is known to affect at least HP500/HP510 notebooks, consequently the built-in touchpad will not work. The patch will simply reread the value until it gets the expected value or a retry limit is hit, without touching other workaround code in the same area.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-142-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

The work function can use container_of() to work out the data. For the cases where the container of the work_struct may go away the moment the pending bit is cleared, it is made possible to defer the release of the structure by deferring the clearing of the pending bit. To make this work, an extra flag is introduced into the management side of the work_struct. This governs auto-release of the structure upon execution. Ordinarily, the work queue executor would release the work_struct for further scheduling or deallocation by clearing the pending bit prior to jumping to the work function. This means that, unless the driver makes some guarantee itself that the work_struct won't go away, the work function may not access anything else in the work_struct or its container lest they be deallocated.. This is a problem if the auxiliary data is taken away (as done by the last patch). However, if the pending bit is *not* cleared before jumping to the work function, then the work function *may* access the work_struct and its container with no problems. But then the work function must itself release the work_struct by calling work_release(). In most cases, automatic release is fine, so this is the default. Special initiators exist for the non-auto-release case (ending in _NAR). Signed-Off-By: David Howells <dhowells@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | Perform actual driver registration right in serio_register_driver() instead of offloading it to kseriod and return proper error code to callers if driver registration fails. Note that driver <-> port matching is still done by kseriod to speed up boot process since probing for PS/2 mice and keyboards is pretty slow. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* | Input: i8042 - fix shutdown issue on some boxes with active MUXesDmitry Torokhov2006-11-171-7/+11
| | | | | | | | | | | | | | | | | | | | | | MUX error handling has a workaround for KBCs that get confused which port data came from and signal MUXERR while data is actually good. Unfortunately this workaround hurts with KBCs that signal timeouts as 0xfc (spec says that only 0xfd, 0xfe and 0xff are alowed with MUXERR) since it causes endless attempts to rescan i8042 serio ports. The solution is to treat 0xfc as timeout (0xfe). Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove call to i8042_interrupt() from i8042_aux_write(). According to Vojtech it may cause problems with older controllers if it is called right after real interrupt. Also it is not needed anymore since we register IRQs early and not waiting for serio ports to be opened. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
