2df8386cec ACPI: asus_acpi: add S1N WLED control
This patch switches back the display nodes for M6R and M6N -- this happened
a while ago when a patch was misapplied (only the in-tree version was
affected).

ffab0d9507 ACPI: asus_acpi: rework model detection
This patch reworks laptop model detection.

This addresses the Samsung P30 issue, where the INIT method would return no
object, but the implicit return in the AML interpreter would confuse the
driver. It also accounts for a newer batch of Asus models whose INIT
returns ACPI_TYPE_BUFFER instead of STRING.

The handling is now much leaner, if we get a buffer or a string, we check
against known values, in every other case we use a different path
(currently DSDT signatures). The bulk of this patch is separating the
string matching from asus_hotk_get_info() into a separate function.

This patch properly fixes http://bugme.osdl.org/show_bug.cgi?id=5067 and
http://bugme.osdl.org/show_bug.cgi?id=5092 and makes the driver fully
functional again with acpi=strict on all machines.

e067aaa761 ACPI: asus_acpi: handle internal Bluetooth / support W5A
This patch creates a new file named "bluetooth" under /proc/acpi/asus/.
This file controls both the internal Bluetooth adapter's presence on the
USB bus and the associated LED.

echo 1 > /proc/acpi/asus/bluetooth to enable, 0 to disable.

Additionally, the patch add support for Asus W5A, the first model that uses
this feature.

b488f02156 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.

c4a001b1ea 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.

c5ab81ca01 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.

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.

967440e3be 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.)

1e3590e2e4 [PATCH] pgdat allocation for new node add (get node id by acpi)
This is to find node id from acpi's handle of memory_device in DSDT.  _PXM for
the new node can be found by acpi_get_pxm() by using new memory's handle.  So,
node id can be found by pxm_to_nid_map[].

  This patch becomes simpler than v2 of node hot-add patch.
  Because old add_memory() function doesn't have node id parameter.
  So, kernel must find its handle by physical address via DSDT again.
  But, v3 just give node id to add_memory() now.

bc02af93dd [PATCH] pgdat allocation for new node add (specify node id)
Change the name of old add_memory() to arch_add_memory.  And use node id to
get pgdat for the node at NODE_DATA().

Note: Powerpc's old add_memory() is defined as __devinit. However,
      add_memory() is usually called only after bootup.
      I suppose it may be redundant. But, I'm not well known about powerpc.
      So, I keep it. (But, __meminit is better at least.)

blocks are initialized at early boottime.  In this case add_memory() return
-EEXIST, and the memory blocks becomes INVALID state even if it is normal.

This is patch to avoid calling add_memory() for already available memory.

1f425994f9 [PATCH] Catch notification of memory add event of ACPI via container driver. (register start func for memory device)
This is a patch to call add_memroy() when notify reaches for new node's add
event.

When new node is added, notify of ACPI reaches container device which means
the node.

Container device driver calls acpi_bus_scan() to find and add belonging
devices (which means cpu, memory and so on).  Its function calls add and
start function of belonging devices's driver.

Howevever, current memory hotplug driver just register add function to
create sysfs file for its memory.  But, acpi_memory_enable_device() is not
called because it is considered just the case that notify reaches memory
device directly.  So, if notify reaches container device nothing can call
add_memory().

This is a patch to create start function which calls add_memory().
add_memory() can be called by this when notify reaches container device.

9ac023989e [PATCH] acpi memory hotplug cannot manage _CRS with plural resoureces
Current acpi memory hotplug just looks into the first entry of resources in
_CRS.  But, _CRS can contain plural resources.  So, if _CRS contains plural
resoureces, acpi memory hot add cannot add all memory.

With this patch, acpi memory hotplug can deal with Memory Device, whose
_CRS contains plural resources.

Tested on ia64 memory hotplug test envrionment (not emulation, uses alpha
version firmware which supports dynamic reconfiguration of NUMA.)

Note: Microsoft's Windows Server 2003 requires big (>4G)resoureces to be
      divided into small (<4G) resources. looks crazy, but not invalid.
      (See http://www.microsoft.com/whdc/system/pnppwr/hotadd/hotaddmem.mspx)
      For this reason, a firmware vendor who supports Windows writes plural
      resources in a _CRS even if they are contiguous.

9e7e2c0475 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.

495ab9c045 [PATCH] i386/x86-64/ia64: Move polling flag into thread_info_status
During some profiling I noticed that default_idle causes a lot of
memory traffic. I think that is caused by the atomic operations
to clear/set the polling flag in thread_info. There is actually
no reason to make this atomic - only the idle thread does it
to itself, other CPUs only read it. So I moved it into ti->status.

Converted i386/x86-64/ia64 for now because that was the easiest
way to fix ACPI which also manipulates these flags in its idle
function.

539eb11e6e [PATCH] Time: i386 Conversion - part 2: Rework TSC Support
As part of the i386 conversion to the generic timekeeping infrastructure, this
introduces a new tsc.c file.  The code in this file replaces the TSC
initialization, management and access code currently in timer_tsc.c (which
will be removed) that we want to preserve.

The code also introduces the following functionality:

o tsc_khz: like cpu_khz but stores the TSC frequency on systems that do not
  change TSC frequency w/ CPU frequency

o check/mark_tsc_unstable: accessor/modifier flag for TSC timekeeping
  usability

o minor cleanups to calibration math.

This patch also includes a one line __cpuinitdata fix from Zwane Mwaikambo.
