f17d9cbf20 ACPICA: Fix access width for reset vector
Section 4.7.3.6 of the ACPI specification requires that the register width
of the reset vector be 8 bits. Windows simply hardcodes the access to be
a byte and ignores the width provided in the FADT, so make sure that we
do the same.

ef09c4f578 ACPICA: Add mechanism to defer _REG methods for some installed handlers
The memory/io/pci/dataTable regions must always be available. For
any user installed handlers for these spaces, defer execution
of _REG methods until acpi_enable_subsystem. This prevents any
chicken/egg problems and ensures that no methods are executed
until all of these regions are ready and available.

981858bd7a ACPI / ACPICA: Implicit notify for multiple devices
Commit bba63a2 (ACPICA: Implicit notify support) introduced a
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.

2d55951368 ACPI / ACPICA: Avoid crashing if _PRW is defined for the root object
Some ACPI BIOSes define _PRW for the root object which causes
acpi_setup_gpe_for_wake() to crash when trying to dereference the
bogus device_node pointer.  Avoid the crash by checking if
wake_device is not the root object before attempting to set up the
"implicit notify" mechanism for it.

The problem was introduced by commit bba63a296f
(ACPICA: Implicit notify support) that added the wake_device argument
to acpi_setup_gpe_for_wake().

2629484288 ACPICA: Fix issues/fault with automatic "serialized" method support
History: This support changes a method to "serialized" on the fly if the
method generates an AE_ALREADY_EXISTS error, indicating the possibility
that it cannot handle reentrancy.

This fix repairs a couple of issues seen in the field, especially on
machines with many cores.

1) Delete method children only upon the exit of the last thread, so
as to not delete objects out from under running threads.

2) Set the "serialized" bit for the method only upon the exit of the
last thread, so as to not cause deadlock when running threads attempt
to exit.

3) Cleanup the use of the AML "MethodFlags" and internal method flags
so that there is no longer any confustion between the two.

5d3131f5b0 ACPICA: Fix namespace race condition
Fixes a race condition between method execution and namespace
walks that can possibly fault. Problem was apparently introduced
in version 20100528 as a result of a performance optimization
that reduces the number of namespace walks upon method exit
by using the delete_namespace_subtree function instead of the
delete_namespace_by_owner function used previously. Bug is in
the delete_namespace_subtree function.

9cd031441a ACPI / ACPICA: Fix global lock acquisition
There are two problems with the ACPICA's current implementation of
the global lock acquisition.  First, acpi_ev_global_lock_handler(),
which in fact is an interface to the outside of the kernel, doesn't
validate its input, so it only works correctly if the other side
(i.e. the ACPI firmware) is fully specification-compliant (as far
as the global lock is concerned).  Unfortunately, that's known not
to be the case on some systems (i.e. we get spurious global lock
signaling interrupts without the pending flag set on some systems).
Second, acpi_ev_global_lock_handler() attempts to acquire the global
lock on behalf of a thread waiting for it without checking if there
actually is such a thread.  Both of these shortcomings need to be
addressed to prevent all possible race conditions from happening.

Rework acpi_ev_global_lock_handler() so that it doesn't try to
acquire the global lock and make it signal the availability of the
global lock to the waiting thread instead.  Make sure that the
availability of the global lock can only be signaled when there
is a thread waiting for it and that it can't be signaled more than
once in a row (to keep acpi_gbl_global_lock_semaphore in balance).

This touches lots of files mainly because of how the io_apic

is forever gone, remove all its fingers.

Most of this code was not being exercised by virtue of
nmi_watchdog != NMI_IO_APIC, so there shouldn't be anything to

8df3fc981d Subject: [PATCH] ACPICA: Fix Scope() op in module level code
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.

cc84e262b7 ACPICA: iASL/Disassembler: Write ACPI errors to stderr instead of output file
This keeps the output files clean of random error messages that
may originate from within the namespace/interpreter code.

28eb3fcf87 ACPICA: Make acpi_thread_id no longer configurable, always u64
Change definition of acpi_thread_id to always be a u64. This
simplifies the code, especially any printf output. u64 is
the only common data type for all thread_id types across all
operating systems. We now force the OSL to cast the native
thread_id type to u64 before returning the value to ACPICA
(via acpi_os_get_thread_id).

to be configured on a per-compiler basis.
