  73 * Architecture-specific ACPICA Subsystem Data Types
  74 *
  75 * The goal of these types is to provide source code portability across
  76 * 16-bit, 32-bit, and 64-bit targets.
  77 *
  78 * 1) The following types are of fixed size for all targets (16/32/64):
  79 *
  80 * BOOLEAN      Logical boolean
  81 *
  82 * UINT8        8-bit  (1 byte) unsigned value
  83 * UINT16       16-bit (2 byte) unsigned value
  84 * UINT32       32-bit (4 byte) unsigned value
  85 * UINT64       64-bit (8 byte) unsigned value
  86 *
  87 * INT16        16-bit (2 byte) signed value
  88 * INT32        32-bit (4 byte) signed value
  89 * INT64        64-bit (8 byte) signed value
  90 *
  91 * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
  92 * compiler-dependent header(s) and were introduced because there is no common
  93 * 64-bit integer type across the various compilation models, as shown in
  94 * the table below.
  95 *
  96 * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
  97 * char      8    8     8     8     8    8
  98 * short     16   16    16    16    16   16
  99 * _int32         32
 100 * int       32   64    32    32    16   16
 101 * long      64   64    32    32    32   32
 102 * long long            64    64
 103 * pointer   64   64    64    32    32   32
 104 *
 105 * Note: ILP64 and LP32 are currently not supported.
 106 *
 107 *
 108 * 2) These types represent the native word size of the target mode of the
 109 * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
 110 * usually used for memory allocation, efficient loop counters, and array
 111 * indexes. The types are similar to the size_t type in the C library and are
 112 * required because there is no C type that consistently represents the native
 113 * data width. ACPI_SIZE is needed because there is no guarantee that a
 114 * kernel-level C library is present.
 115 *
 116 * ACPI_SIZE        16/32/64-bit unsigned value
 117 * ACPI_NATIVE_INT  16/32/64-bit signed value
