Bob Moore 967440e3be ACPI: ACPICA 20060623 
Implemented a new acpi_spinlock type for the OSL lock
interfaces.  This allows the type to be customized to
the host OS for improved efficiency (since a spinlock is
usually a very small object.)

Implemented support for "ignored" bits in the ACPI
registers.  According to the ACPI specification, these
bits should be preserved when writing the registers via
a read/modify/write cycle. There are 3 bits preserved
in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
and PM1_STATUS[11].
http://bugzilla.kernel.org/show_bug.cgi?id=3691

Implemented the initial deployment of new OSL mutex
interfaces.  Since some host operating systems have
separate mutex and semaphore objects, this feature was
requested. The base code now uses mutexes (and the new
mutex interfaces) wherever a binary semaphore was used
previously. However, for the current release, the mutex
interfaces are defined as macros to map them to the
existing semaphore interfaces.

Fixed several problems with the support for the control
method SyncLevel parameter. The SyncLevel now works
according to the ACPI specification and in concert with the
Mutex SyncLevel parameter, since the current SyncLevel is
a property of the executing thread. Mutual exclusion for
control methods is now implemented with a mutex instead
of a semaphore.

Fixed three instances of the use of the C shift operator
in the bitfield support code (exfldio.c) to avoid the use
of a shift value larger than the target data width. The
behavior of C compilers is undefined in this case and can
cause unpredictable results, and therefore the case must
be detected and avoided.  (Fiodor Suietov)

Added an info message whenever an SSDT or OEM table
is loaded dynamically via the Load() or LoadTable()
ASL operators. This should improve debugging capability
since it will show exactly what tables have been loaded
(beyond the tables present in the RSDT/XSDT.)

/*
* 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 16/32/64-bit unsigned value
* ACPI_NATIVE_UINT 16/32/64-bit unsigned value
* ACPI_NATIVE_INT 16/32/64-bit signed value
*
