/*
 * Architecture-specific ACPICA Subsystem Data Types
 *
 * The goal of these types is to provide source code portability across
 * 16-bit, 32-bit, and 64-bit targets.
 *
 * 1) The following types are of fixed size for all targets (16/32/64):
 *
 * BOOLEAN      Logical boolean
 *
 * UINT8        8-bit  (1 byte) unsigned value
 * UINT16       16-bit (2 byte) unsigned value
 * UINT32       32-bit (4 byte) unsigned value
 * UINT64       64-bit (8 byte) unsigned value
 *
 * INT16        16-bit (2 byte) signed value
 * INT32        32-bit (4 byte) signed value
 * INT64        64-bit (8 byte) signed value
 *
 * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
 * compiler-dependent header(s) and were introduced because there is no common
 * 64-bit integer type across the various compilation models, as shown in
 * the table below.
 *
 * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
 * char      8    8     8     8     8    8
 * short     16   16    16    16    16   16
 * _int32         32
 * int       32   64    32    32    16   16
 * long      64   64    32    32    32   32
 * long long            64    64
 * pointer   64   64    64    32    32   32
 *
 * Note: ILP64 and LP32 are currently not supported.
 *
 *
 * 2) These types represent the native word size of the target mode of the
 * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
 * usually used for memory allocation, efficient loop counters, and array
 * indexes. The types are similar to the size_t type in the C library and are
 * required because there is no C type that consistently represents the native
 * data width. ACPI_SIZE is needed because there is no guarantee that a
 * kernel-level C library is present.
 *
 * ACPI_SIZE        16/32/64-bit unsigned value
 * ACPI_NATIVE_INT  16/32/64-bit signed value
