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