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
