Subject: ACPI patches for Linux-2.6.34-rc1
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
Here is why three things included in this request
look somewhat "merge-windo-ish".
re: sony-laptop
Matthew Garrett has graciously offered to handle consolidating
the x86 platform drivers from this release forward. These patches
were not in his merge window request b/c he thought I sent them
up already.
re: bjorn's pnp series
I got a verbal Ack from Jesse Barnes on this series
and he wants it now. It exposes additional info
that we may need in response to the recent PCI changes.
re: alex's processor-rename series
I procrastinated this re-factoring till after -merge
to avoid conflict with the cpufreq tree, recalling
a KS group discussion that rc1 is actually a reasonable time
for cleanups that don't otherwise change much.
This will update the files shown below.
thanks!

There's no real need for a pointer to the MADT to be global. The only
function who uses it is map_madt_entry.
This allows us to remove some more ugly #ifdefs.

ACPI: processor: driver doesn't need to evaluate _PDC
Now that the early _PDC evaluation path knows how to correctly
evaluate _PDC on only physically present processors, there's no
need for the processor driver to evaluate it later when it loads.
To cover the hotplug case, push _PDC evaluation down into the
hotplug paths.

ACPI: processor: add internal processor_physically_present()
Detect if a processor is physically present before evaluating _PDC.
We want this because some BIOS will provide a _PDC even for processors
that are not present. These bogus _PDC methods then attempt to load
non-existent tables, which causes problems.
Avoid those bogus landmines.

ACPI: processor: mv processor_pdc.c processor_core.c
We've renamed the old processor_core.c to processor_driver.c, to
convey the idea that it can be built modular and has driver-like
bits.
Now let's re-create a processor_core.c for the bits needed
statically by the rest of the kernel. The contents of processor_pdc.c
are a good starting spot, so let's just rename that file and
complete our three card monte.

ACPI: processor: mv processor_core.c processor_driver.c
The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.
The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.
Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c
Next step will re-create processor_core.c and cherry-pick out
the static bits.

ACPI: remove "acpi=ht" DMI blacklist
SuSE added these entries when deploying ACPI in Linux-2.4.
I pulled them into Linux-2.6 on 2003-08-09.
Over the last 6+ years, several entries have proven to be
unnecessary and deleted, while no new entries have been added.
Matthew suggests that they now have negative value, and I agree.

There is a race between resume from hibernation and the EC driver

To remove that race condition, add a helpers for suspending and
resuming EC transactions in a safe way to be executed by the ACPI
platform hibernate pre-restore and restore cleanup callbacks.

ACPI thermal: Don't invalidate thermal zone if critical trip point is bad
V2: Corrected integer/long conversion.
Some BIOSes return a negative value for the critical trip point.
Especially since Windows 2006...
We currently invalidate the whole thermal zone in this case.
But it may still be needed for cooling, also without critical
trip point.
This patch invalidates the critical trip point if no _CRT
function is found or if it returns negative values, but does
not invalidate the whole thermal zone in this case.

ACPI: Disable explicit power state retrieval on fans
If the ACPI power state can be got both directly and indirectly,
we prefer to get it indirectly.
https://bugzilla.redhat.com/show_bug.cgi?id=531916 describes a
system with a _PSC method for the fan that always returns "on".
There's no benefit in us always requesting the state of the fan
when performing transitions - we want to do everything we can
to ensure that the fan turns on when it should do, not risk
hardware damage by believing the hardware when it tells us the
fan is already on. Given that the Leading Other OS(tm) works fine
on this machine, it seems likely that it behaves in much this way.

sony-laptop - switch from workqueue to a timer
The function that is executing in workqueue context does not need
to sleep so let's switch to a timer which is more lightweight.

sony-laptop - remove private workqueue, use keventd instead
If we reschedule work instead of having work function sleep for 10 msecs
between reads from kfifo we can safely use the main workqueue (keventd)
and not bother with creating driver-private one.
