Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
All of these patches have been through -mm, and have been
re-based to apply cleanly to 2.6.19-rc2
The C-state changes add support for recently released
MONITOR/MWAIT hardware extensions for deep C-states -- a lower overhead
method than the IO port method they replace.
The EC driver deltas are a long overdue clean-up -- no significant functionality.
The msi-laptop driver is new. Although we are at rc2, I think it is a good idea
to push it upstream b/c it is a better example than the current upstream
platform-specific drivers at using ACPI without _exposing_ ACPI to the user.
Andrew seemed supportive of me not waiting to push it upstream, so here you go.
thanks!
-Len

ACPICA: Fix incorrect handling of PCI Express Root Bridge _HID
I could not get correct PCI Express bus number from the structure of
acpi_object_extra. I always get zero as bus number regardless of bus
location. I found that there is incorrect comparison with _HID (PNP0A08) in
acpi/events/evrgnini.c and PCI Express _BBN method always fail.
Therefore, we always get zero as PCI Express bus number.

ACPI: SCI interrupt source override
The Linux group at Stratus Technologies has come across an issue with SCI
routing under ACPI. We were bitten by this when we made an x86_64 platform
whose BIOS provides an Interrupt Source Override for the SCI itself.
Apparently the override has no effect for the System Control Interrupt, and
this appears to be because of the way the SCI is setup in the ACPI code.
It does not handle the case where busirq != gsi.
The code that sets up the SCI routing assumes that bus irq == global irq.
So there is simply no provision for telling it otherwise. The attached
patch provides this mechanism.
This patch provided by David Bulkow, was tested on an i386 platform, which
does not use the SCI override, and also on an x86_64 platform which does
use an override.

This driver implements a backlight device for controlling LCD brightness
(/sys/class/backlight/msi-laptop-bl/).
In addition it allows access to the WLAN and Bluetooth states
through a platform driver (/sys/devices/platform/msi-laptop-pf/).

ACPI: consolidate functions in acpi ec driver
Unify the following functions:
acpi_ec_poll_read()
acpi_ec_poll_write()
acpi_ec_poll_query()
acpi_ec_intr_read()
acpi_ec_intr_write()
acpi_ec_intr_query()
into:
acpi_ec_poll_transaction()
acpi_ec_intr_transaction()
These new functions take as arguments an ACPI EC command, a few bytes
to write to the EC data register and a buffer for a few bytes to read
from the EC data register. The old _read(), _write(), _query() are
just special cases of these functions.
Then unified the code in acpi_ec_poll_transaction() and
acpi_ec_intr_transaction() a little more. Both functions are now just
wrappers around the new acpi_ec_transaction_unlocked() function. The
latter contains the EC access logic, the two original
function now just do their special way of locking and call the the
new function for the actual work.
This saves a lot of very similar code. The primary reason for doing
this, however, is that my driver for MSI 270 laptops needs to issue
some non-standard EC commands in a safe way. Due to this I added a new
exported function similar to ec_write()/ec_write() which is called
ec_transaction() and is essentially just a wrapper around
acpi_ec_{poll,intr}_transaction().

ACPI: Processor native C-states using MWAIT
Intel processors starting with the Core Duo support
support processor native C-state using the MWAIT instruction.
Refer: Intel Architecture Software Developer's Manual
http://www.intel.com/design/Pentium4/manuals/253668.htm
Platform firmware exports the support for Native C-state to OS using
ACPI _PDC and _CST methods.
Refer: Intel Processor Vendor-Specific ACPI: Interface Specification
http://www.intel.com/technology/iapc/acpi/downloads/302223.htm
With Processor Native C-state, we use 'MWAIT' instruction on the processor
to enter different C-states (C1, C2, C3). We won't use the special IO
ports to enter C-state and no SMM mode etc required to enter C-state.
Overall this will mean better C-state support.
One major advantage of using MWAIT for all C-states is, with this and
"treat interrupt as break event" feature of MWAIT, we can now get accurate
timing for the time spent in C1, C2, .. states.
