Subject: ACPICA: Delete recursive feature of ACPI Global Lock

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.

Subject: ACPICA: Implement simplified Table Manager

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.

From 1ba753acb372c2955a4843302e92e49ce82e2fea Mon Sep 17 00:00:00 2001
From: Bob Moore <robert.moore@intel.com>
Date: Fri, 2 Feb 2007 19:48:20 +0300
Subject: ACPICA: Re-implement interpreters' "serialized mode"

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.

Subject: ACPICA: Fixes for load() operator.

Optimized the Load operator in the case where the source operand is an
operation region. Simply map the operation region memory, instead of
performing a bytewise read.

Subject: ACPICA: Removed all 16-bit support.

Support for 16-bit ACPICA has been completely removed since it is
no longer necessary and it clutters the code. All 16-bit macros,
types, and conditional compiles have been removed, cleaning up
and simplifying the code across the entire subsystem.
DOS support is no longer needed since the Linux firmware kit
is now available.
