Bob Moore 35d7c1cfe5 ACPICA: Cleanup byte/word/dword extraction macros, fix possible warnings 
Removed unnecessary masking. For the 64-bit macros, removed
the structure overlay. Fixes aliasing warnings seen with gcc 4+
compilers.

* Architecture-specific ACPICA Subsystem Data Types
*
* The goal of these types is to provide source code portability across
* 16-bit, 32-bit, and 64-bit targets.
*
* 1) The following types are of fixed size for all targets (16/32/64):
*
* BOOLEAN Logical boolean
*
* UINT8 8-bit (1 byte) unsigned value
* UINT16 16-bit (2 byte) unsigned value
* UINT32 32-bit (4 byte) unsigned value
* UINT64 64-bit (8 byte) unsigned value
*
* INT16 16-bit (2 byte) signed value
* INT32 32-bit (4 byte) signed value
* INT64 64-bit (8 byte) signed value
*
* COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
* compiler-dependent header(s) and were introduced because there is no common
* 64-bit integer type across the various compilation models, as shown in
* the table below.
*
* Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
* char 8 8 8 8 8 8
* short 16 16 16 16 16 16
* _int32 32
* int 32 64 32 32 16 16
* long 64 64 32 32 32 32
* long long 64 64
* pointer 64 64 64 32 32 32
*
* Note: ILP64 and LP32 are currently not supported.
*
*
* 2) These types represent the native word size of the target mode of the
* processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
* usually used for memory allocation, efficient loop counters, and array
* indexes. The types are similar to the size_t type in the C library and are
* required because there is no C type that consistently represents the native
* data width. ACPI_SIZE is needed because there is no guarantee that a
* kernel-level C library is present.
*
* ACPI_SIZE 16/32/64-bit unsigned value
* ACPI_NATIVE_INT 16/32/64-bit signed value
*
