 Log Message:
 Update sysutils/acpica-utils to 20080729.
 Requested by Juan RP in PR 39301.
 
 29 July 2008. Summary of changes for version 20080729:
 
 This release is available at http://acpica.org/downloads
 Direct git access via http://www.acpica.org/repos/acpica.git
 
 1) ACPI CA Core Subsystem:
 
 Fix a possible deadlock in the GPE dispatch. Remove call to
 AcpiHwDisableAllGpes during wake in AcpiEvGpeDispatch. This call will attempt
 to acquire the GPE lock but can deadlock since the GPE lock is already held
 at dispatch time. This code was introduced in version 20060831 as a response
 to Linux BZ 6881 and has since been removed from Linux.
 
 Add a function to dereference returned reference objects. Examines the return
 object from a call to AcpiEvaluateObject. Any Index or RefOf references are
 automatically dereferenced in an attempt to return something useful (these
 reference types cannot be converted into an external ACPI_OBJECT.) Provides
 MS compatibility. Lin Ming, Bob Moore. Linux BZ 11105
 
 x2APIC support: changes for MADT and SRAT ACPI tables. There are 2 new
 subtables for the MADT and one new subtable for the SRAT. Includes
 disassembler and AcpiSrc support. Data from the Intel 64 Architecture x2APIC
 Specification, June 2008.
 
 Additional error checking for pathname utilities. Add error check after all
 calls to AcpiNsGetPathnameLength. Add status return from
 AcpiNsBuildExternalPath and check after all calls. Add parameter validation
 to AcpiUtInitializeBuffer. Reported by and initial patch by Ingo Molnar.
 
 Return status from the global init function AcpiUtGlobalInitialize. This is
 used by both the kernel subsystem and the utilities such as iASL compiler.
 The function could possibly fail when the caches are initialized. Yang Yi.
 
 Add a function to decode reference object types to strings. Created for
 improved error messages.
 
 Improve object conversion error messages. Better error messages during object
 conversion from internal to the external ACPI_OBJECT. Used for external calls
 to AcpiEvaluateObject.
 
 Example Code and Data Size: These are the sizes for the OS-independent
 acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
 debug version of the code includes the debug output trace mechanism and has a
 much larger code and data size.
 
   Previous Release:
     Non-Debug Version:  79.6K Code, 16.2K Data,  95.8K Total
     Debug Version:     153.5K Code, 48.2K Data, 201.7K Total
   Current Release:
     Non-Debug Version:  79.7K Code, 16.4K Data,  96.1K Total
     Debug Version:     153.9K Code, 48.4K Data, 202.3K Total
 
 2) iASL Compiler/Disassembler and Tools:
 
 Debugger: fix a possible hang when evaluating non-methods. Fixes a problem
 introduced in version 20080701. If the object being evaluated (via execute
 command) is not a method, the debugger can hang while trying to obtain non-
 existent parameters.
 
 iASL: relax error for using reserved "_T_x" identifiers. These names can
 appear in a disassembled ASL file if they were emitted by the original
 compiler. Instead of issuing an error or warning and forcing the user to
 manually change these names, issue a remark instead.
 
 iASL: error if named object created in while loop. Emit an error if any named
 object is created within a While loop. If allowed, this code will generate a
 run-time error on the second iteration of the loop when an attempt is made to
 create the same named object twice. ACPICA bugzilla 730.
 
 iASL: Support absolute pathnames for include files. Add support for absolute
 pathnames within the Include operator. previously, only relative pathnames
 were supported.
 
 iASL: Enforce minimum 1 interrupt in interrupt macro and Resource Descriptor.
 The ACPI spec requires one interrupt minimum. BZ 423
 
 iASL: Handle a missing ResourceSource arg, with a present SourceIndex.
 Handles the case for the Interrupt Resource Descriptor where
 the ResourceSource argument is omitted but ResourceSourceIndex
 is present. Now leave room for the Index. BZ 426
 
 iASL: Prevent error message if CondRefOf target does not exist. Fixes cases
 where an error message is emitted if the target does not exist. BZ 516
 
 iASL: Fix broken -g option (get Windows ACPI tables). Fixes the -g option
 (get ACPI tables on Windows). This was apparently broken in version 20070919.
 
 AcpiXtract: Handle EOF while extracting data. Correctly handle the case where
 the EOF happens immediately after the last table in the input file. Print
 completion message. Previously, no message was displayed in this case.

 This release is available at http://acpica.org/downloads
 Direct git access via http://www.acpica.org/repos/acpica.git
 
 0) Git source tree / acpica.org
 
 Fixed a problem where a git-clone from http would not transfer the entire
 source
 tree.
 
 1) ACPI CA Core Subsystem:
 
 Implemented a "careful" GPE disable in AcpiEvDisableGpe, only modify one
 enable
 bit. Now performs a read-change-write of the enable register instead of
 simply
 writing out the cached enable mask. This will prevent inadvertent enabling of
 GPEs if a rogue GPE is received during initialization (before GPE handlers
 are
 installed.)
 
 Implemented a copy for dynamically loaded tables. Previously, dynamically
 loaded
 tables were simply mapped - but on some machines this memory is corrupted
 after
 suspend. Now copy the table to a local buffer. For the OpRegion case, added
 checksum verify. Use the table length from the table header, not the region
 length. For the Buffer case, use the table length also. Dennis Noordsij, Bob
 Moore. BZ 10734
 
 Fixed a problem where the same ACPI table could not be dynamically loaded and
 unloaded more than once. Without this change, a table cannot be loaded again
 once it has been loaded/unloaded one time. The current mechanism does not
 unregister a table upon an unload. During a load, if the same table is found,
 this no longer returns an exception. BZ 722
 
 Fixed a problem where the wrong descriptor length was calculated for the
 EndTag
 descriptor in 64-bit mode. The "minimal" descriptors such as EndTag are
 calculated as 12 bytes long, but the actual length in the internal descriptor
 is
 16 because of the round-up to 8 on the 64-bit build. Reported by Linn
 Crosetto.
 BZ 728
 
 Fixed a possible memory leak in the Unload operator. The DdbHandle returned
 by
 Load() did not have its reference count decremented during unload, leading to
 a
 memory leak. Lin Ming. BZ 727
 
 Fixed a possible memory leak when deleting thermal/processor objects. Any
 associated notify handlers (and objects) were not being deleted. Fiodor
 Suietov.
 BZ 506
 
 Fixed the ordering of the ASCII names in the global mutex table to match the
 actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug only.
 Vegard Nossum. BZ 726
 
 Enhanced the AcpiGetObjectInfo interface to return the number of required
 arguments if the object is a control method. Added this call to the debugger
 so
 the proper number of default arguments are passed to a method. This prevents
 a
 warning when executing methods from AcpiExec.
 
 Added a check for an invalid handle in AcpiGetObjectInfo. Return
 AE_BAD_PARAMETER if input handle is invalid. BZ 474
 
 Fixed an extraneous warning from exconfig.c on the 64-bit build.
 
 Example Code and Data Size: These are the sizes for the OS-independent
 acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
 debug
 version of the code includes the debug output trace mechanism and has a much
 larger code and data size.
 
   Previous Release:

     Debug Version:     153.0K Code, 48.2K Data, 201.2K Total
   Current Release:
     Non-Debug Version:  79.6K Code, 16.2K Data,  95.8K Total
     Debug Version:     153.5K Code, 48.2K Data, 201.7K Total
 
 2) iASL Compiler/Disassembler and Tools:
 
 iASL: Added two missing ACPI reserved names. Added _MTP and _ASZ, both
 resource
 descriptor names.
 
 iASL: Detect invalid ASCII characters in input (windows version). Removed the
 "-
 CF" flag from the flex compile, enables correct detection of non-ASCII
 characters in the input. BZ 441
 
 iASL: Eliminate warning when result of LoadTable is not used. Eliminate the
 "result of operation not used" warning when the DDB handle returned from
 LoadTable is not used. The warning is not needed. BZ 590
 
 AcpiExec: Add support for dynamic table load/unload. Now calls _CFG method to
 pass address of table to the AML. Added option to disable OpRegion simulation
 to
 allow creation of an OpRegion with a real address that was passed to _CFG.
 All
 of this allows testing of the Load and Unload operators from AcpiExec.
 
 Debugger: update tables command for unloaded tables. Handle unloaded tables
 and
 use the standard table header output routine.
 
 ----------------------------------------
 09 June 2008. Summary of changes for version 20080609:
 
 1) ACPI CA Core Subsystem:
 
 Implemented a workaround for reversed _PRT entries. A significant number of
 BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This
 change dynamically detects and repairs this problem. Provides compatibility
 with MS ACPI. BZ 6859
 
 Simplified the internal ACPI hardware interfaces to eliminate the locking
 flag parameter from Register Read/Write. Added a new external interface,
 AcpiGetRegisterUnlocked.
 
 Fixed a problem where the invocation of a GPE control method could hang. This
 was a regression introduced in 20080514. The new method argument count
 validation mechanism can enter an infinite loop when a GPE method is
 dispatched. Problem fixed by removing the obsolete code that passed GPE block
 information to the notify handler via the control method parameter pointer.
 
 Fixed a problem where the _SST execution status was incorrectly returned to
 the caller of AcpiEnterSleepStatePrep. This was a regression introduced in
 20080514. _SST is optional and a NOT_FOUND exception should never be
 returned. BZ 716
 
 Fixed a problem where a deleted object could be accessed from within the AML
 parser. This was a regression introduced in version 20080123 as a fix for the
 Unload operator. Lin Ming. BZ 10669
 
 Cleaned up the debug operand dump mechanism. Eliminated unnecessary operands
 and eliminated the use of a negative index in a loop. Operands are now
 displayed in the correct order, not backwards. This also fixes a regression
 introduced in 20080514 on 64-bit systems where the elimination of
 ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 715
 
 Fixed a possible memory leak in EvPciConfigRegionSetup where the error exit
 path did not delete a locally allocated structure.
 
 Updated definitions for the DMAR and SRAT tables to synchronize with the
 current specifications. Includes disassembler support.
 
 Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect
 loop termination value was used. Loop terminated on iteration early, missing
 one mutex. Linn Crosetto
 
 Example Code and Data Size: These are the sizes for the OS-independent
 acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
 debug version of the code includes the debug output trace mechanism and has a
 much larger code and data size.

   Current Release:

     Debug Version:     153.0K Code, 48.2K Data, 201.2K Total
 
 2) iASL Compiler/Disassembler and Tools:
 
 Disassembler: Implemented support for EisaId() within _CID objects. Now
 disassemble integer _CID objects back to EisaId invocations, including
 multiple integers within _CID packages. Includes single-step support for
 debugger also.
 
 Disassembler: Added support for DMAR and SRAT table definition changes.
 
 ----------------------------------------
 14 May 2008. Summary of changes for version 20080514:
 
 1) ACPI CA Core Subsystem:
 
 Fixed a problem where GPEs were enabled too early during the ACPICA
 initialization. This could lead to "handler not installed" errors on some
 machines. Moved GPE enable until after _REG/_STA/_INI methods are run. This
 ensures that all operation regions and devices throughout the namespace have
 been initialized before GPEs are enabled. Alexey Starikovskiy, BZ 9916.
 
 Implemented a change to the enter sleep code. Moved execution of the _GTS
 method to just before setting sleep enable bit. The execution was moved from
 AcpiEnterSleepStatePrep to AcpiEnterSleepState. _GTS is now executed
 immediately before the SLP_EN bit is set, as per the ACPI specification.
 Luming Yu, BZ 1653.
 
 Implemented a fix to disable unknown GPEs (2nd version). Now always disable
 the GPE, even if ACPICA thinks that that it is already disabled. It is
 possible that the AML or some other code has enabled the GPE unbeknownst to
 the ACPICA code.
 
 Fixed a problem with the Field operator where zero-length fields would return
 an AE_AML_NO_OPERAND exception during table load. Fix enables zero-length ASL
 field declarations in Field(), BankField(), and IndexField(). BZ 10606.
 
 Implemented a fix for the Load operator, now load the table at the namespace
 root. This reverts a change introduced in version 20071019. The table is now
 loaded at the namespace root even though this goes against the ACPI
 specification. This provides compatibility with other ACPI implementations.
 The ACPI specification will be updated to reflect this in ACPI 4.0. Lin Ming.
 
 Fixed a problem where ACPICA would not Load() tables with unusual signatures.
 Now ignore ACPI table signature for Load() operator. Only "SSDT" is
 acceptable to the ACPI spec, but tables are seen with OEMx and null sigs.
 Therefore, signature validation is worthless. Apparently MS ACPI accepts such
 signatures, ACPICA must be compatible. BZ 10454.
 
 Fixed a possible negative array index in AcpiUtValidateException. Added NULL
 fields to the exception string arrays to eliminate a -1 subtraction on the
 SubStatus field.
 
 Updated the debug tracking macros to reduce overall code and data size.
 Changed ACPI_MODULE_NAME and ACPI_FUNCTION_NAME to use arrays of strings
 instead of pointers to static strings. Jan Beulich and Bob Moore.
 
 Implemented argument count checking in control method invocation via
 AcpiEvaluateObject. Now emit an error if too few arguments, warning if too
 many. This applies only to extern programmatic control method execution, not
 method-to-method calls within the AML. Lin Ming.
 
 Eliminated the ACPI_NATIVE_UINT type across all ACPICA code. This type is no
 longer needed, especially with the removal of 16-bit support. It was replaced
 mostly with UINT32, but also ACPI_SIZE where a type that changes 32/64 bit on
 32/64-bit platforms is required.
 
 Added the C const qualifier for appropriate string constants -- mostly
 MODULE_NAME and printf format strings. Jan Beulich.
 
 Example Code and Data Size: These are the sizes for the OS-independent
 acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
 debug version of the code includes the debug output trace mechanism and has a
 much larger code and data size.
 
   Previous Release:
     Non-Debug Version:  80.0K Code, 17.4K Data,  97.4K Total
     Debug Version:     159.4K Code, 64.4K Data, 223.8K Total
   Current Release:
     Non-Debug Version:  79.5K Code, 16.2K Data,  95.7K Total
     Debug Version:     153.3K Code, 48.3K Data, 201.6K Total
 
 2) iASL Compiler/Disassembler and Tools:
 
 Implemented ACPI table revision ID validation in the disassembler. Zero is
 always invalid. For DSDTs, the ID controls the interpreter integer width. 1
 means 32-bit and this is unusual. 2 or greater is 64-bit.
