  * 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):
  *
  * u8           Logical boolean
  *
  * u8           8-bit  (1 byte) unsigned value
  * u16          16-bit (2 byte) unsigned value
  * u32          32-bit (4 byte) unsigned value
  * u64          64-bit (8 byte) unsigned value
  *
  * s16          16-bit (2 byte) signed value
  * s32          32-bit (4 byte) signed value
  * s64          64-bit (8 byte) signed value
  *
  * COMPILER_DEPENDENT_UINT64/s64 - 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
