    status from acpi_table_parse(). acpi_table_parse() now
    returns zero on success, one on failure.

    ACPI: Thermal issues on HP nx6325
    
    The previous reference counting scheme to enable power resources
    got confused when multiple devices were present that might
    repeatedly enable or disable the resource and throw off the count.
    
    The new code simply lists the referencing devices which
    are requesting the resource to be enabled.  When there are none,
    then it is off.

    ACPI: include apic.h in processor driver for benefit of UP kernels
    
    apic.h does not get included on UP compiles.  That way the
    APICTIMER_STOPS_ON_C3 is not there and UP boxen have no support for timer
    broadcasting.  This was never noticed, because the lapic timer is only used
    for profiling on UP.

    ACPI: always enable CONFIG_PNPACPI on CONFIG_ACPI kernels
    
    We removed the ACPI motherboard driver which handled
    the ACPI=y, PNP=n case, so now we need to enforce that
    PNP & PNPACPI are always enabled for ACPI kernels.
    
    Most major distros ship this way this already.

    Execute AML Notify() requests on stack.
    
    HP nx6125/nx6325/... machines have a _GPE handler with an infinite
    loop sending Notify() events to different ACPI subsystems.
    
    The notify handler in the ACPI thermal driver is a C-routine,
    which may invoke the ACPI interpreter again to get access
    to some ACPI variables such as temperature.  (acpi_evaluate_xxx)
    On these HP machines such an evaluation changes state of an ASL variable
    and lets the loop above break.
    
    In the current ACPI implementation, Notify requests are being deferred
    to the same kacpid workqueue on which the above GPE handler with
    infinite loop is executing. Thus we have a deadlock -- loop will
    continue to spin, sending notify events, and at the same time
    preventing these notify events from being run on a workqueue. All
    notify events are deferred, thus we see explosion in memory consumption.
    
    Also as GPE handling is blocked, machines overheat because ACPI-based
    fan control is stalled.  Eventually by external poll of the same
    acpi_evaluate, kacpid is released and all the queued notify events are
    free to run, thus 100% CPU utilization by kacpid for several seconds
    or more.
    
    To prevent this failure,  Linux must not send notify events to the
    kacpid workqueue -- either executing them immediately or putting them
    on some other thread.
    
    The first attempt to create a new thread was done by Peter Wainwright
    He created a bunch of threads, which were stealing work from a kacpid
    workqueue.
    This patch appeared in 2.6.15-based kernel shipped with Ubuntu 6.06 LTS.
    
    Second attempt was done by Alexey Starikovskiy, who created a new thread
    for each Notify event. This worked OK on HP nx machines,
    but broke Linus' Compaq n620c, by producing threads with a speed what
    they stopped the machine completely.
    Thus this patch was reverted from 2.6.18-rc2.
    
    Alexey re-made the patch to create second workqueue just for notify events,
    thus hopping it will not break Linus' machine. Patch was tested on the
    same HP nx machines in #5534 and #7122, but this broke Linus' machine
    also and was reverted from 2.6.19-rc with much fanfair.
    
    The 4th patch inserted schedule_timeout(1) into deferred
    execution of kacpid, if we had any notify requests pending, but Linus
    decided that it was too complex (involved either changes to workqueue
    to see if it's empty or atomic inc/dec).  Then a 5th attempt did a
    yield() to every GPE execution.
    
    Finally, this 6th generation patch simply executes the notify handler
    on the stack.  Previous attempts to do this simple solution failed
    because of issues in AML mutex re-entrancy which are now fixed
    by the previous patch in this series.

    ACPICA: fix AML mutex re-entrancy
    
    ACPI AML supports "serialized" methods which are protected
    by an implicit mutex.  The mutex is re-entrant for that AML thread
    to allow recursion.
    
    However, Linux implements notify() by creating a new AML thread.
    So for systems where notify() re-enters a serialized method,
    deadlock results.
    
    The fix is to use the Linux thread_id as the key to allowing
    re-entrancy, not the AML thread pointer.

    Replace sony_acpi_value.{min,max} with a callback function that allows
    more complex reasoning in accepting input and presenting output.
    
    This allows consistency between the sony-laptop specific 'brightness_default'

    ACPI: updates rtc-cmos device platform_data
    
    Update ACPI to export its RTC extension information through platform_data
    to the PNPACPI or platform bus device node used on the system being set up.
    
    This will need to be updated later to provide a firmware hook to handle
    system suspend with an alarm pending.
    
    Len notes that "Eventually we may bundle ACPI/PNP/PNPACPI..." but if/when
    that happens, ACPI can simplify this without my help.
    
    And until it does, the separate patch creating a platform_device (on all
    X86_PC systems, even without ACPI) will be needed.

    ACPI: bay: remove ACPI driver struct
    
    The bay driver is a platform driver, and doesn't need to also be an acpi
    driver.  Remove the acpi driver related structures and callbacks, they didn't
    do anything anyway.  Switch to uevent for user space event notification.
