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.

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.

sony-laptop: allow complex per-value input/output validation
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'

sony_acpi: SNC device support for Sony Vaios
From: Bjorn Helgaas <bjorn.helgaas@...com>
Even though the devices claimed by sony_acpi.c can not be hot-plugged, the
driver registration infrastructure allows the .add() and .remove() methods
to be called at any time while the driver is registered. So remove __init
and __exit from them.

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.
