 147  *
 148  * The goal of these types is to provide source code portability across
 149  * 16-bit, 32-bit, and 64-bit targets.
 150  *
 151  * 1) The following types are of fixed size for all targets (16/32/64):
 152  *
 153  * BOOLEAN      Logical boolean
 154  *
 155  * UINT8        8-bit  (1 byte) unsigned value
 156  * UINT16       16-bit (2 byte) unsigned value
 157  * UINT32       32-bit (4 byte) unsigned value
 158  * UINT64       64-bit (8 byte) unsigned value
 159  *
 160  * INT16        16-bit (2 byte) signed value
 161  * INT32        32-bit (4 byte) signed value
 162  * INT64        64-bit (8 byte) signed value
 163  *
 164  * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
 165  * compiler-dependent header(s) and were introduced because there is no common
 166  * 64-bit integer type across the various compilation models, as shown in
 167  * the table below.
 168  *
 169  * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
 170  * char      8    8     8     8     8    8
 171  * short     16   16    16    16    16   16
 172  * _int32         32
 173  * int       32   64    32    32    16   16
 174  * long      64   64    32    32    32   32
 175  * long long            64    64
 176  * pointer   64   64    64    32    32   32
 177  *
 178  * Note: ILP64 and LP32 are currently not supported.
 179  *
 180  *
 181  * 2) These types represent the native word size of the target mode of the
 182  * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
 183  * usually used for memory allocation, efficient loop counters, and array
 184  * indexes. The types are similar to the size_t type in the C library and are
 185  * required because there is no C type that consistently represents the native
 186  * data width. ACPI_SIZE is needed because there is no guarantee that a
 187  * kernel-level C library is present.
 188  *
 189  * ACPI_SIZE        16/32/64-bit unsigned value
 190  * ACPI_NATIVE_INT  16/32/64-bit signed value
