   * 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
