Subject: [git pull request] ACPI patches for 2.6.32-rc1
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
The sony-laptop update is some driver-specific patches I failed to get in
during the merge window. Then there are a couple of 2.6.31-rc1 regression
fixes, Some EC bug-fixes/workarounds, etc.
This will update the files shown below.
thanks!

ACPI: EC: Don't parse DSDT for EC early init on Compal
Compal DSDT breaks if scanned early, while we need early scan
for almost all ASUS machines. Safest workaround seems to be to
continue do an early scan for all machines, but this Compal model.

ACPI: kill overly verbose "throttling states" log messages
I was recently lucky enough to get a 64-CPU system. The processors
actually have T-states, so my kernel log ends up with 64 lines like:
ACPI: Processor [CPU0] (supports xx throttling states)
This is pretty useless clutter because
- this info is already available after boot from
/proc/acpi/processor/CPUnn/throttling
- there's also an ACPI_DEBUG_PRINT() in processor_throttling.c that
gives the same info on boot for anyone who *really* cares.
So just delete the code that prints the throttling states in
processor_core.c.

ACPI: Fix bound checks for copy_from_user in the acpi /proc code
The ACPI /proc write() code takes an unsigned length argument like any write()
function, but then assigned it to a *signed* integer called "len".
Only after this is a sanity check for len done to make it not larger than 4.
Due to the type change a len < 0 is in principle also possible; this patch
adds a check for this.

ACPI: EC: Restart command even if no interrupts from EC
EC may forget a command without sending any "reset" interrupt,
thus we need to lessen the requirement for transaction restart.

sony-laptop: SPIC unset IRQF_SHARED, set IRQF_DISABLED
The SPIC irq is not really shareable, the IO port cannot be cleared and
always returns some data so there is no real way to understand if the irq
is for us or not. Moreover the _PRS acpi method says the irq is not
shareable.
In addition to this, in some cases, an additional write to the IO port has
to be performed in order to properly decode the event received from the
device. This generates another interrupt which may overlap with the
previous one. In the future this is going to be important for properly
decoding events.

sony-laptop: remove device_ctrl and the SPIC mini drivers
Having separate drivers for SPIC showed to be useless, only type3 has a
slightly different behaviour than the others and there seem to be no real
conflict between them.
