commit 28f4f8a9def2b1f3a6066bae791c77043ec49524
Author: Rafael J. Wysocki <rjw@...k.pl>
Date: Tue Aug 3 23:55:14 2010 +0200
ACPI / ACPICA: Fix reference counting problems with GPE handlers
If a handler is installed for a GPE associated with an AML method and
such that it cannot wake up the system from sleep states, the GPE
remains enabled after the handler has been installed, although it
should be disabled in that case to avoid spurious execution of the
handler.
Fix this issue by making acpi_install_gpe_handler() disable GPEs
that were previously associated with AML methods and cannot wake up
the system from sleep states.
Analogously, make acpi_remove_gpe_handler() enable the GPEs that
are associated with AML methods after their handlers have been
removed and cannot wake up the system from sleep states. In addition
to that, fix a code ordering issue in acpi_remove_gpe_handler() that
renders the locking ineffective (ACPI_MTX_EVENTS is released
temporarily in the middle of the routine to wait for the completion
of events already in progress).
For this purpose introduce acpi_raw_disable_gpe() and
acpi_raw_enable_gpe() to be called with acpi_gbl_gpe_lock held
and rework acpi_disable_gpe() and acpi_enable_gpe(), respectively, to
use them. Also rework acpi_gpe_can_wake() to use
acpi_raw_disable_gpe() instead of calling acpi_disable_gpe() after
releasing the lock to avoid the possible theoretical race with
acpi_install_gpe_handler().

ACPI: Add the check of ADR flag in course of finding ACPI handle for PCI device
The _ADR object is used to provide OSPM with the address of one device on its
parent bus. In course of finding ACPI handle for the corresponding PCI device,
we will firstly evaluate the _ADR object and then compare the two addresses to
see whether it is the target ACPI device. But for one PCI device(0000:00:00.0)
under the PCI root bridge, the corresponding address will be constructed as
zero.In such case maybe the ACPI device without _ADR object will be misdetected
and then be used to create the relationship between PCI device and ACPI device.

ACPI / Wakeup: Simplify enabling of wakeup devices
To simplify the enabling of wakeup devices during system suspend and

acpi_disable_wakeup_device() and remove unnecessary (and no longer
valid) comments from the latter. Rename acpi_enable_wakeup_device()
to acpi_enable_wakeup_devices() and acpi_disable_wakeup_device()
to acpi_disable_wakeup_devices(), because these functions usually
operate on multiple device objects.

There is no reason why acpi_enable_wakeup_device() should be called

ACPI / Sleep: Free NVS copy if suspending of devices fails
If suspending of devices fails or system suspend is tested in the
"devices" mode, the memory allocated for storing a copy of the ACPI
NVS area will not be freed, because acpi_pm_finish() is not called
in that case. Fix this by moving the suspend_nvs_free() call to
acpi_pm_end().
