commit 8df3fc981dc12d9fdcaef4100a2193b605024d7a upstream.

Some Panasonic Toughbooks create nodes in module level code.
Module level code is the executable AML code outside of control method,
for example, below AML code creates a node \_SB.PCI0.GFX0.DD02.CUBL

        If (\_OSI ("Windows 2006"))
        {
            Scope (\_SB.PCI0.GFX0.DD02)
            {
                Name (CUBL, Ones)
                ...
            }
        }

Scope() op does not actually create a new object, it refers to an
existing object(\_SB.PCI0.GFX0.DD02 in above example). However, for
Scope(), we want to indeed open a new scope, so the child nodes(CUBL in
above example) can be created correctly under it.

commit ed3aada1bf34c5a9e98af167f125f8a740fc726a upstream.

Currently we have:

  --w--w--w-. 1 root root 0 2010-11-11 14:56 /sys/kernel/debug/acpi/custom_method

which is just crazy. Change this to --w-------.

commit 557d58687dcdee6bc00c1a8f1fd4e0eac8fefce9 upstream.

According to the ACPI spec, some kinds of primary battery can
report percentage battery remaining capacity directly to OS.

In this case, it reports the LastFullChargedCapacity == 100,
BatteryPresentRate = 0xFFFFFFFF, and BatteryRemaingCapacity a
percentage value, which actually means RemainingBatteryPercentage.

Now we found some battery follows this rule even if it's a rechargeable.
https://bugzilla.kernel.org/show_bug.cgi?id=15979

Handle these batteries correctly in ACPI battery driver
so that they won't break userspace.

ACPI table sysfs I/F is broken by commit

    ACPI: processor: call _PDC early

because dynamic SSDT tables may be loaded in _PDC,
before installing the ACPI table handler.
As a result, the sysfs I/F of these dynamic tables are
located at  /sys/firmware/acpi/tables instead of
/sys/firmware/acpi/tables/dynamic, which is not true.

Invoke acpi_sysfs_init() before acpi_early_processor_set_pdc(),
so that the table handler is installed before any dynamic tables loaded.

The brightness control hotkey don't work with Vista compatibility
because the MSI GX723 includes an infinite while loop in DSDT when
brightness control hotkey pressed.

The MSI GX723 uses Nvidia video.  Perhaps the loop is specific
to the Nvidia Vista driver...

This patch should be reverted once nouveau grows support
to call the ACPI NVIF method.

|    ACPI: processor: driver doesn't need to evaluate _PDC
|
|    Now that the early _PDC evaluation path knows how to correctly
|    evaluate _PDC on only physically present processors, there's no
|    need for the processor driver to evaluate it later when it loads.
|
|    To cover the hotplug case, push _PDC evaluation down into the
|    hotplug paths.

only cpu with Processor Statement get processed with _PDC

If bios is using Device object instead of Processor statement.
SSDTs for Pstate/Cstate/Tstate can not be loaded dynamically.

Need to try to scan ACPI0007 in addition to Processor.

That commit is between 2.6.34-rc1 and 2.6.34-rc2, so stable tree for 2.6.34+
need this patch.
