/*
 * 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

 * Obsolete: Acpi integer width. In ACPI version 1 (1996), integers are
 * 32 bits. In ACPI version 2 (2000) and later, integers are max 64 bits.
 * Note that this pertains to the ACPI integer type only, not to other
 * integers used in the implementation of the ACPICA subsystem.
 *
 * 01/2010: This type is obsolete and has been removed from the entire ACPICA
 * code base. It remains here for compatibility with device drivers that use
 * the type. However, it will be removed in the future.
