Hi Linus,

please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release

CONFIG_ACPI_DOCK is new. Although it has been in -mm for a while, I've
marked it EXPERIMENTAL because it hasn't yet seen the broad exposure
that comes with being in your upstream tree.

thanks!

-Len

ACPI: restore comment justifying 'extra' P_LVLx access

While trying to look for superfluous I/O accesses that can be optimized
away, I stumbled upon this ACPI sleep I/O access and couldn't figure out
why the hell this dummy op was necessary.
After more than one hour of internet research, I had collected a sufficient
number of documents (among those very old kernel versions) that finally
told me what this dummy read was about: STPCLK# doesn't get asserted in time
on (some) chipsets, which is why we need to have a dummy I/O read to delay
further instruction processing until the CPU is fully stopped.

ACPI: C-States: only demote on current bus mastering activity

Only if bus master activity is going on at the present, we should avoid
entering C3-type sleep, as it might be a faulty transition. As long as the
bm_activity bitmask was based on the number of calls to the ACPI idle
function, looking at previous moments made sense. Now, with it being based on
what happened this jiffy, looking at this jiffy should be sufficient.

ACPI: C-States: bm_activity improvements

Do not assume there was bus mastering activity if the idle handler didn't get
called, as there's only reason to not enter C3-type sleep if there is bus
master activity going on. Only for the "promotion" into C3-type sleep bus
mastering activity is taken into account, and there only current bus mastering
activity, and not pure guessing should lead to the decision on whether to
enter C3-type sleep or not.

Also, as bm_activity is a jiffy-based bitmask (bit 0: bus mastering activity
during this juffy, bit 31: bus mastering activity 31 jiffies ago), fix the
setting of bit 0, as it might be called multiple times within one jiffy.

ACPI: C-States: accounting of sleep states

Track the actual time spent in C-States (C2 upwards, we can't determine this
for C1), not only the number of invocations. This is especially useful for
dynamic ticks / "tickless systems", but is also of interest on normal systems,
as any interrupt activity leads to C-States being exited, not only the timer
interrupt.

The time is being measured in PM timer ticks, so an increase by one equals 279
nanoseconds.

ACPI: ACPICA 20060623

Implemented a new acpi_spinlock type for the OSL lock
interfaces. This allows the type to be customized to
the host OS for improved efficiency (since a spinlock is
usually a very small object.)

Implemented support for "ignored" bits in the ACPI
registers. According to the ACPI specification, these
bits should be preserved when writing the registers via
a read/modify/write cycle. There are 3 bits preserved
in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
and PM1_STATUS[11].
http://bugzilla.kernel.org/show_bug.cgi?id=3691

Implemented the initial deployment of new OSL mutex
interfaces. Since some host operating systems have
separate mutex and semaphore objects, this feature was
requested. The base code now uses mutexes (and the new
mutex interfaces) wherever a binary semaphore was used
previously. However, for the current release, the mutex
interfaces are defined as macros to map them to the
existing semaphore interfaces.

Fixed several problems with the support for the control
method SyncLevel parameter. The SyncLevel now works
according to the ACPI specification and in concert with the
Mutex SyncLevel parameter, since the current SyncLevel is
a property of the executing thread. Mutual exclusion for
control methods is now implemented with a mutex instead
of a semaphore.

Fixed three instances of the use of the C shift operator
in the bitfield support code (exfldio.c) to avoid the use
of a shift value larger than the target data width. The
behavior of C compilers is undefined in this case and can
cause unpredictable results, and therefore the case must
be detected and avoided. (Fiodor Suietov)

Added an info message whenever an SSDT or OEM table
is loaded dynamically via the Load() or LoadTable()
ASL operators. This should improve debugging capability
since it will show exactly what tables have been loaded
(beyond the tables present in the RSDT/XSDT.)

ACPIPHP: prevent duplicate slot numbers when no _SUN

Dock bridges generally do not implement _SUN, yet show up as ejectable
slots. If you have more than one ejectable slot that does not implement
SUN, with the current code you will get duplicate slot numbers. So, if
there is no _SUN, use the current count of the number of slots found
instead.

ACPI: acpi_os_wait_semaphore(): silence complaint

The ASL Acquire operator (17.5.1 in ACPI 3.0 spec) is allowed to time out
and return True without acquiring the semaphore. There's no indication in
the spec that this is an actual error, so this message should be
debug-only, as the message for successful acquisition is.

This used to be an ACPI_DEBUG_PRINT, but it was mis-classified as
ACPI_DB_ERROR rather than ACPI_DB_MUTEX, so it got swept up in Thomas'
recent patch to enable ACPI error messages even without CONFIG_ACPI_DEBUG.
