[ACPI] ACPICA 20051021

Browse Source 
Implemented support for the EM64T and other x86_64
processors. This essentially entails recognizing
that these processors support non-aligned memory
transfers. Previously, all 64-bit processors were assumed
to lack hardware support for non-aligned transfers.

Completed conversion of the Resource Manager to nearly
full table-driven operation. Specifically, the resource
conversion code (convert AML to internal format and the
reverse) and the debug code to dump internal resource
descriptors are fully table-driven, reducing code and data
size and improving maintainability.

The OSL interfaces for Acquire and Release Lock now use a
64-bit flag word on 64-bit processors instead of a fixed
32-bit word. (Alexey Starikovskiy)

Implemented support within the resource conversion code
for the Type-Specific byte within the various ACPI 3.0
*WordSpace macros.

Fixed some issues within the resource conversion code for
the type-specific flags for both Memory and I/O address
resource descriptors. For Memory, implemented support
for the MTP and TTP flags. For I/O, split the TRS and TTP
flags into two separate fields.
