This change adds support to allow hosts to install System Control
Interrupt handlers. Certain ACPI functionality requires the host
to handle raw SCIs. For example, the "SCI Doorbell" that is defined
for memory power state support requires the host device driver to
handle SCIs to examine if the doorbell has been activated. Multiple
SCI handlers can be installed to allow for future expansion.
Debugger support is included.
Lv Zheng, Bob Moore. ACPICA BZ 1032.
Bug summary:
It is reported when the PCC (Platform Communication Channel, via
MPST table, defined in ACPI specification 5.0) subchannel responds
to the host, it issues an SCI and the host must probe the subchannel
for channel status.

Add new API to allow OSPM to disable/enable specific types of _OSI
interface strings.
ACPICA does not have the knowledge about whether an _OSI interface
string is an OS vendor string or a feature group string and there
isn't any API interface to allow OSPM to install a new interface
string as a feature group string.
This patch simply adds all feature group strings defined by ACPI
specification into the acpi_default_supported_interfaces with
ACPI_OSI_FEATURE flag set to fix this gap. This patch also adds
codes to keep their default states as ACPI_OSI_INVALID before the
initialization and after the termination.

This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.
This patch does not affect the generation of the Linux binary.
This patch decreases 210 lines of 20121018 divergence.diff.
The ACPICA source codes uses a totally different indentation style from the
Linux to be compatible with other users (operating systems or BIOS).
Indentation differences are critical to the release automation. There are
two causes related to the "indentation" that are affecting the release
automation:
1. The ACPICA -> Linux release process is:
ACPICA source -- acpisrc - hierarchy - indent ->
linuxized ACPICA source -- diff ->
linuxized ACPICA patch (x) -- human intervention ->
linuxized ACPICA patch (o)
Where
'x' means "cannot be directly applied to the Linux"
'o' means "can be directly applied to the Linux"
Different "indent" version or "indent" options used in the "indent"
step will lead to different divergences.
The version of "indent" used for the current release process is:
GNU indent 2.2.11
The options of "indent" used for the current release process is:
-npro -kr -i8 -ts8 -sob -l80 -ss -ncs
2. Manual indentation prettifying work in the Linux side will also harm the
automatically generated linuxized ACPICA patches, making them impossible
to apply directly.
This patch fixes source code differences caused by the two causes so that
the "human intervention" can be reduced in the future.

We can only sort the _TSS return package if there is no _PSS
in the same scope. This is because if _PSS is present, the ACPI
specification dictates that the _TSS Power Dissipation field is
to be ignored, and therefore some BIOSs leave garbage values in
the _TSS Power field(s). In this case, it is best to just return
the _TSS package as-is.

mechanism that causes a notify request of type
ACPI_NOTIFY_DEVICE_WAKE to be queued automatically by
acpi_ev_asynch_execute_gpe_method() for the device whose _PRW points
to the GPE being handled if that GPE is not associated with an
_Lxx/_Exx method. However, it turns out that on some systems there
are multiple devices with _PRW pointing to the same GPE without
_Lxx/_Exx and the mechanism introduced by commit bba63a2 needs to be
extended so that "implicit" notify requests of type
ACPI_NOTIFY_DEVICE_WAKE can be queued automatically for all those
devices at the same time.

The current ACPI GPEs initialization code has a problem that it
enables some GPEs pointed to by device _PRW methods, generally
intended for signaling wakeup events (system or device wakeup).
These GPEs are then almost immediately disabled by the ACPI namespace
scanning code with the help of acpi_gpe_can_wake(), but it would be
better not to enable them at all until really necessary.
Modify the initialization of GPEs so that the ones that have
associated _Lxx or _Exx methods and are not pointed to by any _PRW
methods will be enabled after the namespace scan is complete.

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().
