      ACPICA 20050708 from Bob Moore <robert.moore@intel.com> · f9f4601f

      The use of the CPU stack in the debug version of the
      subsystem has been considerably reduced.  Previously, a
      debug structure was declared in every function that used
      the debug macros.  This structure has been removed in
      favor of declaring the individual elements as parameters
      to the debug functions.  This reduces the cumulative stack
      use during nested execution of ACPI function calls at the
      cost of a small increase in the code size of the debug
      version of the subsystem.  With assistance from Alexey
      Starikovskiy and Len Brown.
      
      Added the ACPI_GET_FUNCTION_NAME macro to enable the
      compiler-dependent headers to define a macro that will
      return the current function name at runtime (such as
      __FUNCTION__ or _func_, etc.) The function name is used
      by the debug trace output.  If ACPI_GET_FUNCTION_NAME
      is not defined in the compiler-dependent header, the
      function name is saved on the CPU stack (one pointer per
      function.) This mechanism is used because apparently there
      exists no standard ANSI-C defined macro that that returns
      the function name.
      
      Alexey Starikovskiy redesigned and reimplemented the
      "Owner ID" mechanism used to track namespace objects
      created/deleted by ACPI tables and control method
      execution.  A bitmap is now used to allocate and free the
      IDs, thus solving the wraparound problem present in the
      previous implementation.  The size of the namespace node
      descriptor was reduced by 2 bytes as a result.
      
      Removed the UINT32_BIT and UINT16_BIT types that were used
      for the bitfield flag definitions within the headers for
      the predefined ACPI tables.  These have been replaced by
      UINT8_BIT in order to increase the code portability of
      the subsystem.  If the use of UINT8 remains a problem,
      we may be forced to eliminate bitfields entirely because
      of a lack of portability.
      
      Alexey Starikovksiy enhanced the performance of
      acpi_ut_update_object_reference.  This is a frequently used
      function and this improvement increases the performance
      of the entire subsystem.
      
      Alexey Starikovskiy fixed several possible memory leaks
      and the inverse - premature object deletion.

      ACPICA 20050617:
      
      Moved the object cache operations into the OS interface
      layer (OSL) to allow the host OS to handle these operations
      if desired (for example, the Linux OSL will invoke the
      slab allocator).  This support is optional; the compile
      time define ACPI_USE_LOCAL_CACHE may be used to utilize
      the original cache code in the ACPI CA core.  The new OSL
      interfaces are shown below.  See utalloc.c for an example
      implementation, and acpiosxf.h for the exact interface
      definitions.  Thanks to Alexey Starikovskiy.
      	acpi_os_create_cache
      	acpi_os_delete_cache
      	acpi_os_purge_cache
      	acpi_os_acquire_object
      	acpi_os_release_object
      
      Modified the interfaces to acpi_os_acquire_lock and
      acpi_os_release_lock to return and restore a flags
      parameter.  This fits better with many OS lock models.
      Note: the current execution state (interrupt handler
      or not) is no longer passed to these interfaces.  If
      necessary, the OSL must determine this state by itself, a
      simple and fast operation.  Thanks to Alexey Starikovskiy.
      
      Fixed a problem in the ACPI table handling where a valid
      XSDT was assumed present if the revision of the RSDP
      was 2 or greater.  According to the ACPI specification,
      the XSDT is optional in all cases, and the table manager
      therefore now checks for both an RSDP >=2 and a valid
      XSDT pointer.  Otherwise, the RSDT pointer is used.
      Some ACPI 2.0 compliant BIOSs contain only the RSDT.
      
      Fixed an interpreter problem with the Mid() operator in the
      case of an input string where the resulting output string
      is of zero length.  It now correctly returns a valid,
      null terminated string object instead of a string object
      with a null pointer.
      
      Fixed a problem with the control method argument handling
      to allow a store to an Arg object that already contains an
      object of type Device.  The Device object is now correctly
      overwritten.  Previously, an error was returned.
      
      ACPICA 20050624:
      
      Modified the new OSL cache interfaces to use ACPI_CACHE_T
      as the type for the host-defined cache object.  This allows
      the OSL implementation to define and type this object in
      any manner desired, simplifying the OSL implementation.
      For example, ACPI_CACHE_T is defined as kmem_cache_t for
      Linux, and should be defined in the OS-specific header
      file for other operating systems as required.
      
      Changed the interface to AcpiOsAcquireObject to directly
      return the requested object as the function return (instead
      of ACPI_STATUS.) This change was made for performance
      reasons, since this is the purpose of the interface in the
      first place.  acpi_os_acquire_object is now similar to the
      acpi_os_allocate interface.  Thanks to Alexey Starikovskiy.
      
      Modified the initialization sequence in
      acpi_initialize_subsystem to call the OSL interface
      acpi_osl_initialize first, before any local initialization.
      This change was required because the global initialization
      now calls OSL interfaces.
      
      Restructured the code base to split some files because
      of size and/or because the code logically belonged in a
      separate file.  New files are listed below.
      
        utilities/utcache.c	/* Local cache interfaces */

      Implemented support to execute Type 1 and Type 2 AML
      opcodes appearing at the module level (not within a control
      method.)  These opcodes are executed exactly once at the
      time the table is loaded. This type of code was legal up
      until the release of ACPI 2.0B (2002) and is now supported
      within ACPI CA in order to provide backwards compatibility
      with earlier BIOS implementations. This eliminates the
      "Encountered executable code at module level" warning that
      was previously generated upon detection of such code.
      
      Fixed a problem in the interpreter where an AE_NOT_FOUND
      exception could inadvertently be generated during the
      lookup of namespace objects in the second pass parse of
      ACPI tables and control methods. It appears that this
      problem could occur during the resolution of forward
      references to namespace objects.
      
      Added the ACPI_MUTEX_DEBUG #ifdef to the
      acpi_ut_release_mutex function, corresponding to the same
      the deadlock detection debug code to be compiled out in
      the normal case, improving mutex performance (and overall
      subsystem performance) considerably.  As suggested by
      Alexey Starikovskiy.
      
      Implemented a handful of miscellaneous fixes for possible
      memory leaks on error conditions and error handling
      control paths. These fixes were suggested by FreeBSD and
      the Coverity Prevent source code analysis tool.
      
      Added a check for a null RSDT pointer in
      acpi_get_firmware_table (tbxfroot.c) to prevent a fault
      in this error case.

      Implemented support for PCI Express root bridges
      -- added support for device PNP0A08 in the root
      bridge search within AcpiEvPciConfigRegionSetup.
      acpi_ev_pci_config_region_setup().
      
      The interpreter now automatically truncates incoming
      64-bit constants to 32 bits if currently executing out
      of a 32-bit ACPI table (Revision < 2). This also affects
      the iASL compiler constant folding. (Note: as per below,
      the iASL compiler no longer allows 64-bit constants within
      32-bit tables.)
      
      Fixed a problem where string and buffer objects with
      "static" pointers (pointers to initialization data within
      an ACPI table) were not handled consistently. The internal
      object copy operation now always copies the data to a newly
      allocated buffer, regardless of whether the source object
      is static or not.
      
      Fixed a problem with the FromBCD operator where an
      implicit result conversion was improperly performed while
      storing the result to the target operand. Since this is an
      "explicit conversion" operator, the implicit conversion
      should never be performed on the output.
      
      Fixed a problem with the CopyObject operator where a copy
      to an existing named object did not always completely
      overwrite the existing object stored at name. Specifically,
      a buffer-to-buffer copy did not delete the existing buffer.
      
      Replaced "interrupt_level" with "interrupt_number" in all
      GPE interfaces and structs for consistency.
