  • e42837bcd   freezer: introduce freezer-friendly waiting macros ... Browse Code »

    Introduce freezer-friendly wrappers around wait_event_interruptible() and
    wait_event_interruptible_timeout(), originally defined in , to
    be used in freezable kernel threads. Make some of the freezable kernel
    threads use them.

    This is necessary for the freezer to stop sending signals to kernel threads,
    which is implemented in the next patch.

    When enabling interrupts for a port fails, the interrupt enable and
    port enable bits remain set in i8042_ctr. Later writes of i8042_ctr
    to the hardware could accidentally retry enabling interrupts. Clear
    the bits on failure.

    On some boxes that don't have PS/2 mice connected at startup BIOS
    completely disables AUX port and attempts to access it result in
    hosed keyboard. Historically we do not trust ACPI/PNP data on
    i386 and try to poke AUX port even if we did not find an active
    PNP node for it. However in cases when BIOS writers got KBD port
    properly described we can assume that they did the right thing
    for AUX port as well.

  • 831441862   Freezer: make kernel threads nonfreezable by default ... Browse Code »

    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.

    We need to take serio->drv_mutex in serio_cleanup() to prevent the
    function from being called while driver is in the middle of attaching
    to a serio port. Such situation can happen with i8042 and atkbd drivers
    if user rapidly presses Ctrl-Alt-Del during system startup, and leads
    to kernel oops.

  • d2ada5597   Input: i8042 - fix AUX port detection with some chips ... Browse Code »

    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.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    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).
