Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to support C compilers that do not allow the initialization of address pointers within packed structures - even though the hardware itself may support misaligned transfers. Some of the debug data structures are packed by default to minimize size. Added an error message for the case where acpi_os_get_thread_id() returns zero. A non-zero value is required by the core ACPICA code to ensure the proper operation of AML mutexes and recursive control methods. The DSDT is now the only ACPI table that determines whether the AML interpreter is in 32-bit or 64-bit mode. Not really a functional change, but the hooks for per-table 32/64 switching have been removed from the code. A clarification to the ACPI specification is forthcoming in ACPI 3.0B. Fixed a possible leak of an Owner ID in the error path of tbinstal.c acpi_tb_init_table_descriptor() and migrated all table OwnerID deletion to a single place in acpi_tb_uninstall_table() to correct possible leaks when using the acpi_tb_delete_tables_by_type() interface (with assistance from Lance Ortiz.) Fixed a problem with Serialized control methods where the semaphore associated with the method could be over-signaled after multiple method invocations. Fixed two issues with the locking of the internal namespace data structure. Both the Unload() operator and acpi_unload_table() interface now lock the namespace during the namespace deletion associated with the table unload (with assistance from Linn Crosetto.) Fixed problem reports (Valery Podrezov) integrated: - Eliminate unnecessary memory allocation for CreateXxxxField http://bugzilla.kernel.org/show_bug.cgi?id=5426 Fixed problem reports (Fiodor Suietov) integrated: - Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369) - On Address Space handler deletion, needless deactivation call (BZ 374) - AcpiRemoveAddressSpaceHandler: validate Device handle parameter (BZ 375) - Possible memory leak, Notify sub-objects of Processor, Power, ThermalZone (BZ 376) - AcpiRemoveAddressSpaceHandler: validate Handler parameter (BZ 378) - Minimum Length of RSDT should be validated (BZ 379) - AcpiRemoveNotifyHandler: return AE_NOT_EXIST if Processor Obj has no Handler (BZ (380) - AcpiUnloadTable: return AE_NOT_EXIST if no table of specified type loaded (BZ 381) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Removed a device initialization optimization introduced in 20051216 where the _STA method was not run unless an _INI was also present for the same device. This optimization could cause problems because it could allow _INI methods to be run within a not-present device subtree (If a not-present device had no _INI, _STA would not be run, the not-present status would not be discovered, and the children of the device would be incorrectly traversed.) Implemented a new _STA optimization where namespace subtrees that do not contain _INI are identified and ignored during device initialization. Selectively running _STA can significantly improve boot time on large machines (with assistance from Len Brown.) Implemented support for the device initialization case where the returned _STA flags indicate a device not-present but functioning. In this case, _INI is not run, but the device children are examined for presence, as per the ACPI specification. Implemented an additional change to the IndexField support in order to conform to MS behavior. The value written to the Index Register is not simply a byte offset, it is a byte offset in units of the access width of the parent Index Field. (Fiodor Suietov) Defined and deployed a new OSL interface, acpi_os_validate_address(). This interface is called during the creation of all AML operation regions, and allows the host OS to exert control over what addresses it will allow the AML code to access. Operation Regions whose addresses are disallowed will cause a runtime exception when they are actually accessed (will not affect or abort table loading.) Defined and deployed a new OSL interface, acpi_os_validate_interface(). This interface allows the host OS to match the various "optional" interface/behavior strings for the _OSI predefined control method as appropriate (with assistance from Bjorn Helgaas.) Restructured and corrected various problems in the exception handling code paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod (with assistance from Takayoshi Kochi.) Modified the Linux source converter to ignore quoted string literals while converting identifiers from mixed to lower case. This will correct problems with the disassembler and other areas where such strings must not be modified. The ACPI_FUNCTION_* macros no longer require quotes around the function name. This allows the Linux source converter to convert the names, now that the converter ignores quoted strings.

Tagged all external interfaces to the subsystem with the new ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to assist kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL macro. The default definition is NULL. Added the ACPI_THREAD_ID type for the return value from acpi_os_get_thread_id(). This allows the host to define this as necessary to simplify kernel integration. The default definition is ACPI_NATIVE_UINT. Valery Podrezov fixed two interpreter problems related to error processing, the deletion of objects, and placing invalid pointers onto the internal operator result stack. http://bugzilla.kernel.org/show_bug.cgi?id=6028 http://bugzilla.kernel.org/show_bug.cgi?id=6151 Increased the reference count threshold where a warning is emitted for large reference counts in order to eliminate unnecessary warnings on systems with large namespaces (especially 64-bit.) Increased the value from 0x400 to 0x800. Due to universal disagreement as to the meaning of the 'c' in the calloc() function, the ACPI_MEM_CALLOCATE macro has been renamed to ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'. ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and ACPI_FREE. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Removed a couple of extraneous ACPI_ERROR messages that appeared during normal execution. These became apparent after the conversion from ACPI_DEBUG_PRINT. Fixed a problem where the CreateField operator could hang if the BitIndex or NumBits parameter referred to a named object. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5359 Fixed a problem where a DeRefOf operation on a buffer object incorrectly failed with an exception. This also fixes a couple of related RefOf and DeRefOf issues. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5360 http://bugzilla.kernel.org/show_bug.cgi?id=5387 http://bugzilla.kernel.org/show_bug.cgi?id=5392 Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead of AE_STRING_LIMIT on an out-of-bounds Index() operation. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5480 Implemented a memory cleanup at the end of the execution of each iteration of an AML While() loop, preventing the accumulation of outstanding objects. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5427 Eliminated a chunk of duplicate code in the object resolution code. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5336 Fixed several warnings during the 64-bit code generation.

Added 2006 copyright. At SuSE's suggestion, enabled all error messages without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, respectively. This preserves all error and warning messages in the non-debug version of the ACPICA code (this has been referred to as the "debug lite" option.) Over 200 cases were converted to create a total of over 380 error/warning messages across the ACPICA code. This increases the code and data size of the default non-debug version by about 13K. Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages. The size of the debug version remains about the same.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
