71  * Architecture-specific ACPICA Subsystem Data Types
72  *
73  * The goal of these types is to provide source code portability across
74  * 16-bit, 32-bit, and 64-bit targets.
75  *
76  * 1) The following types are of fixed size for all targets (16/32/64):
77  *
78  * u8           Logical boolean
79  *
80  * u8           8-bit  (1 byte) unsigned value
81  * u16          16-bit (2 byte) unsigned value
82  * u32          32-bit (4 byte) unsigned value
83  * u64          64-bit (8 byte) unsigned value
84  *
85  * s16          16-bit (2 byte) signed value
86  * s32          32-bit (4 byte) signed value
87  * s64          64-bit (8 byte) signed value
88  *
89  * COMPILER_DEPENDENT_UINT64/s64 - These types are defined in the
90  * compiler-dependent header(s) and were introduced because there is no
91  * common 64-bit integer type across the various compilation models, as
92  * shown in the table below.
93  *
94  * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
95  * char      8    8     8     8     8    8
96  * short     16   16    16    16    16   16
97  * _int32         32
98  * int       32   64    32    32    16   16
99  * long      64   64    32    32    32   32
100  * long long            64    64
101  * pointer   64   64    64    32    32   32
102  *
103  * Note: ILP64 and LP32 are currently not supported.
104  *
105  *
106  * 2) These types represent the native word size of the target mode of the
107  * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
108  * usually used for memory allocation, efficient loop counters, and array
109  * indexes. The types are similar to the size_t type in the C library and
110  * are required because there is no C type that consistently represents the
111  * native data width. acpi_size is needed because there is no guarantee
112  * that a kernel-level C library is present.
113  *
114  * acpi_size        16/32/64-bit unsigned value
115  * acpi_native_int  16/32/64-bit signed value
