  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
