Remove flags parameter for acpi_{get,set}_register().
It is no longer necessary now that these functions use a
spinlock for mutual exclusion.Signed-off-by: Alexey Starikovskiy

Fixed a problem with the Global Lock where the lock could appear to be obtained before it is actually obtained, semaphore created with one unit.

Fixed a regression where an error was no
longer emitted if a control method attempts to create 2
objects of the same name. This previously and now returns
AE_ALREADY_EXISTS. When this exception occurs, it invokes
the mechanism that will dynamically serialize the control
method to possible prevent future errors. (BZ 440)Signed-off-by: Alexey Starikovskiy

Moved all FADT-related functions to a new file, tbfadt.c.
Eliminated the acpi_hw_initialize function - the
FADT registers are now validated when the table is loaded.Signed-off-by: Alexey Starikovskiy

Enhanced the implementation of the interpreters'
serialized mode (boot with "acpi_serialize" to set
acpi_glb_all_methods_serialized flag.)
When this mode is specified, instead of creating a serialization
semaphore per control method, the interpreter lock is
simply no longer released before a blocking operation
during control method execution. This effectively makes
the AML Interpreter single-threaded. The overhead of a
semaphore per-method is eliminated.Signed-off-by: Alexey Starikovskiy

Change for GPE support: when a wake GPE is
received, now all wake GPEs are immediately disabled to
prevent the waking GPE from firing again, and to prevent
other wake GPEs from interrupting the wake process.Signed-off-by: Alexey Starikovskiy

The Table Manager component has been completely
redesigned and reimplemented. The new design is much
simpler, and reduces the overall code and data size of
the kernel-resident ACPICA by approximately 5%. Also,
it is now possible to obtain the ACPI tables very early
during kernel initialization, even before dynamic memory
management is initialized.Signed-off-by: Alexey Starikovskiy

The ACPI Global Lock interrupt handler no longer
queues the execution of a separate thread to signal the
global lock semaphore. Instead, the semaphore is signaled
directly from the interrupt handler.Signed-off-by: Alexey Starikovskiy

Completed a new design and implementation for
the ACPI Global Lock support. On the OS side, the global
lock is now treated as a standard AML mutex. Previously,
multiple OS threads could acquire the global lock
simultaneously, but this could cause the BIOS to be starved
by the lock in cases such as the Embedded Controller driver,
where there is a tight coupling between the OS and the BIOS.Signed-off-by: Alexey Starikovskiy
