fa25d8d6d3 [PATCH] memory hotadd fixes: avoid check in acpi
add_memory() does all necessary check to avoid collision.  then, acpi layer
doesn't have to check region by itself.

(*) pfn_valid() just returns page struct is valid or not. It returns 0
    if a section has been already added even is ioresource is not added.
    ioresource collision check in mm/memory_hotplug.c can do more precise
    collistion check.
    added enabled bit check just for sanity check..

5669021e40 PCI: docking station: remove dock uevents
Remove uevent dock notifications.  There are no consumers
of these events at present, and uevents are likely not the
correct way to send this type of event anyway.

Until I get some kind of idea if anyone in userspace cares
about dock events, I will just not send any.

72945b2b90 [PATCH] Revert "ACPI: execute Notify() handlers on new thread"
This effectively reverts commit b8d35192c5
by reverts acpi_os_queue_for_execution() to what it was before that,
except it changes the name to acpi_os_execute() to match ACPICA
20060512.

Signed-off-by: Len Brown <len.brown@intel.com>

[ The thread execution doesn't actually solve the bug it set out to
  solve (see

	http://bugzilla.kernel.org/show_bug.cgi?id=5534

  for more details) because the new events can get caught behind the AML
  semaphore or other serialization.  And when that happens, the notify
  threads keep on piling up until the system dies. ]

bed936f7ea [PATCH] ACPI: fix fan/thermal resume
Daniel Ritz <daniel.ritz-ml@swissonline.ch> says:

The acpi driver suspend/resume patches that went in recently caused a regression
on my box (toshiba tecra 8000 laptop): after resume from swsusp the fan turns on
keeping blowing cold air out of my notebook. before the patches, the fan was off
and would only make noise when required. it's the same thing described in
bugzilla.kernel.org #5000. the acpi suspend/resume patches or at least parts of
them originate in this bug. now the last patch in the report (attach id 8438)
actually fixes the problem - for me and the reporter. this is a trimmed down
version of that patch.

e21c1ca3f9 ACPI: acpi_os_allocate() fixes
Replace acpi_in_resume with a more general hack
to check irqs_disabled() on any kmalloc() from ACPI.
While setting (system_state != SYSTEM_RUNNING) on resume
seemed more general, Andrew Morton preferred this approach.

http://bugzilla.kernel.org/show_bug.cgi?id=3469

Make acpi_os_allocate() into an inline function to
allow /proc/slab_allocators to work.

Delete some memset() that could fault on allocation failure.

ab8aa06a5c ACPI: acpi_os_get_thread_id() returns current
Linux mutexes and the debug code that that reference
acpi_os_get_thread_id() are happy with 0.
But the AML mutexes in exmutex.c expect a unique non-zero
number for each thread - as they track this thread_id
to permit the mutex re-entrancy defined by the ACPI spec.

f6dd9221dd ACPI: ACPICA 20060707
Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to
support C compilers that do not allow the initialization
of address pointers within packed structures - even though
the hardware itself may support misaligned transfers. Some
of the debug data structures are packed by default to
minimize size.

Added an error message for the case where
acpi_os_get_thread_id() returns zero. A non-zero value is
required by the core ACPICA code to ensure the proper
operation of AML mutexes and recursive control methods.

The DSDT is now the only ACPI table that determines whether
the AML interpreter is in 32-bit or 64-bit mode. Not really
a functional change, but the hooks for per-table 32/64
switching have been removed from the code. A clarification
to the ACPI specification is forthcoming in ACPI 3.0B.

Fixed a possible leak of an Owner ID in the error
path of tbinstal.c acpi_tb_init_table_descriptor() and
migrated all table OwnerID deletion to a single place in
acpi_tb_uninstall_table() to correct possible leaks when using
the acpi_tb_delete_tables_by_type() interface (with assistance
from Lance Ortiz.)

Fixed a problem with Serialized control methods where the
semaphore associated with the method could be over-signaled
after multiple method invocations.

Fixed two issues with the locking of the internal
namespace data structure. Both the Unload() operator and
acpi_unload_table() interface now lock the namespace during
the namespace deletion associated with the table unload
(with assistance from Linn Crosetto.)

Fixed problem reports (Valery Podrezov) integrated: -
Eliminate unnecessary memory allocation for CreateXxxxField
http://bugzilla.kernel.org/show_bug.cgi?id=5426

Fixed problem reports (Fiodor Suietov) integrated: -

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.

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.

a3c6598f92 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.

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.)
