      Modified the parsing of control methods to no longer
create namespace objects during the first pass of the
parse. Objects are now created only during the execute
phase, at the moment the namespace creation operator
is encountered in the AML (Name, OperationRegion,
CreateByteField, etc.) This should eliminate ALREADY_EXISTS
exceptions seen on some machines where reentrant control
methods are protected by an AML mutex. The mutex will now
correctly block multiple threads from attempting to create
the same object more than once.

Increased the number of available Owner Ids for namespace
object tracking from 32 to 255. This should eliminate the
OWNER_ID_LIMIT exceptions seen on some machines with a
large number of ACPI tables (either static or dynamic).

Enhanced the namespace dump routine to output the owner
ID for each namespace object.

      Fixed a problem in the AML parser where the method thread
count could be decremented below zero if any errors
occurred during the method parse phase. This should
eliminate AE_AML_METHOD_LIMIT exceptions seen on some
machines. This also fixed a related regression with the
mechanism that detects and corrects methods that cannot
properly handle reentrancy (related to the deployment of
the new OwnerId mechanism.)

Eliminated the pre-parsing of control methods (to detect
errors) during table load. Related to the problem above,
this was causing unwind issues if any errors occurred
during the parse, and it seemed to be overkill. A table
load should not be aborted if there are problems with
any single control method, thus rendering this feature
rather pointless.

Fixed a problem with the new table-driven resource manager
where an internal buffer overflow could occur for small
resource templates.

Implemented a new external interface, acpi_get_vendor_resource()
This interface will find and return a vendor-defined
resource descriptor within a _CRS or _PRS
method via an ACPI 3.0 UUID match. (from Bjorn Helgaas)

Removed the length limit (200) on string objects as
per the upcoming ACPI 3.0A specification. This affects
the following areas of the interpreter: 1) any implicit
conversion of a Buffer to a String, 2) a String object
result of the ASL Concatentate operator, 3) the String
object result of the ASL ToString operator.

      Modified the subsystem initialization sequence to improve
GPE support. The GPE initialization has been split into
two parts in order to defer execution of the _PRW methods
(Power Resources for Wake) until after the hardware is
fully initialized and the SCI handler is installed. This
allows the _PRW methods to access fields protected by the
Global Lock. This will fix systems where a NO_GLOBAL_LOCK
exception has been seen during initialization.

Fixed a regression with the ConcatenateResTemplate()
ASL operator introduced in the 20051021 release.

Implemented support for "local" internal ACPI object
types within the debugger "Object" command and the
acpi_walk_namespace() external interfaces. These local
types include RegionFields, BankFields, IndexFields, Alias,
and reference objects.

Moved common AML resource handling code into a new file,
"utresrc.c". This code is shared by both the Resource
Manager and the AML Debugger.

      Implemented support for the EM64T and other x86_64
processors. This essentially entails recognizing
that these processors support non-aligned memory
transfers. Previously, all 64-bit processors were assumed
to lack hardware support for non-aligned transfers.

Completed conversion of the Resource Manager to nearly
full table-driven operation. Specifically, the resource
conversion code (convert AML to internal format and the
reverse) and the debug code to dump internal resource
descriptors are fully table-driven, reducing code and data
size and improving maintainability.

The OSL interfaces for Acquire and Release Lock now use a
64-bit flag word on 64-bit processors instead of a fixed
32-bit word. (Alexey Starikovskiy)

Implemented support within the resource conversion code
for the Type-Specific byte within the various ACPI 3.0
*WordSpace macros.

Fixed some issues within the resource conversion code for
the type-specific flags for both Memory and I/O address
resource descriptors. For Memory, implemented support
for the MTP and TTP flags. For I/O, split the TRS and TTP
flags into two separate fields.

      由 Bob Moore 提交于 
      Completed a major overhaul of the Resource Manager code -
specifically, optimizations in the area of the AML/internal
resource conversion code. The code has been optimized to
simplify and eliminate duplicated code, CPU stack use has
been decreased by optimizing function parameters and local
variables, and naming conventions across the manager have
been standardized for clarity and ease of maintenance (this
includes function, parameter, variable, and struct/typedef
names.)

All Resource Manager dispatch and information tables have
been moved to a single location for clarity and ease of
maintenance. One new file was created, named "rsinfo.c".

The ACPI return macros (return_ACPI_STATUS, etc.) have
been modified to guarantee that the argument is
not evaluated twice, making them less prone to macro
side-effects. However, since there exists the possibility
of additional stack use if a particular compiler cannot
optimize them (such as in the debug generation case),
the original macros are optionally available.  Note that
some invocations of the return_VALUE macro may now cause
size mismatch warnings; the return_UINT8 and return_UINT32
macros are provided to eliminate these. (From Randy Dunlap)

Implemented a new mechanism to enable debug tracing for
individual control methods. A new external interface,
acpi_debug_trace(), is provided to enable this mechanism. The
intent is to allow the host OS to easily enable and disable
tracing for problematic control methods. This interface
can be easily exposed to a user or debugger interface if
desired. See the file psxface.c for details.

acpi_ut_callocate() will now return a valid pointer if a
length of zero is specified - a length of one is used
and a warning is issued. This matches the behavior of
acpi_ut_allocate().
