0180  * Architecture-specific ACPICA Subsystem Data Types
0181  *
0182  * The goal of these types is to provide source code portability across
0183  * 16-bit, 32-bit, and 64-bit targets.
0184  *
0185  * 1) The following types are of fixed size for all targets (16/32/64):
0186  *
0187  * BOOLEAN      Logical boolean
0188  *
0189  * UINT8        8-bit  (1 byte) unsigned value
0190  * UINT16       16-bit (2 byte) unsigned value
0191  * UINT32       32-bit (4 byte) unsigned value
0192  * UINT64       64-bit (8 byte) unsigned value
0193  *
0194  * INT16        16-bit (2 byte) signed value
0195  * INT32        32-bit (4 byte) signed value
0196  * INT64        64-bit (8 byte) signed value
0197  *
0198  * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
0199  * compiler-dependent header(s) and were introduced because there is no
0200  * common 64-bit integer type across the various compilation models, as
0201  * shown in the table below.
0202  *
0203  * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
0204  * char      8    8     8     8     8    8
0205  * short     16   16    16    16    16   16
0206  * _int32         32
0207  * int       32   64    32    32    16   16
0208  * long      64   64    32    32    32   32
0209  * long long            64    64
0210  * pointer   64   64    64    32    32   32
0211  *
0212  * Note: ILP64 and LP32 are currently not supported.
0213  *
0214  *
0215  * 2) These types represent the native word size of the target mode of the
0216  * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
0217  * usually used for memory allocation, efficient loop counters, and array
0218  * indexes. The types are similar to the size_t type in the C library and
0219  * are required because there is no C type that consistently represents the
0220  * native data width. ACPI_SIZE is needed because there is no guarantee
0221  * that a kernel-level C library is present.
0222  *
0223  * ACPI_SIZE        16/32/64-bit unsigned value
0224  * ACPI_NATIVE_INT  16/32/64-bit signed value
