    ACPI: ACPICA 20060331 · 793c2388
    Bob Moore authored
    Implemented header file support for the following
    additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR,
    SPMI, TCPA, and WDRT. With this support, all current and
    known ACPI tables are now defined in the ACPICA headers and
    are available for use by device drivers and other software.
    
    Implemented support to allow tables that contain ACPI
    names with invalid characters to be loaded. Previously,
    this would cause the table load to fail, but since
    there are several known cases of such tables on
    existing machines, this change was made to enable
    ACPI support for them. Also, this matches the
    behavior of the Microsoft ACPI implementation.

    Fixed a couple regressions introduced during the memory
    optimization in the 20060317 release. The namespace
    node definition required additional reorganization and
    an internal datatype that had been changed to 8-bit was
    restored to 32-bit. (Valery Podrezov)
    
    Fixed a problem where a null pointer passed to
    acpi_ut_delete_generic_state() could be passed through
    to acpi_os_release_object which is unexpected. Such
    null pointers are now trapped and ignored, matching
    the behavior of the previous implementation before the
    deployment of acpi_os_release_object().  (Valery Podrezov,
    Fiodor Suietov)
    
    Fixed a memory mapping leak during the deletion of
    a SystemMemory operation region where a cached memory
    mapping was not deleted. This became a noticeable problem
    for operation regions that are defined within frequently
    used control methods. (Dana Meyers)
    
    Reorganized the ACPI table header files into two main
    files: one for the ACPI tables consumed by the ACPICA core,
    and another for the miscellaneous ACPI tables that are
    consumed by the drivers and other software. The various
    FADT definitions were merged into one common section and
    three different tables (ACPI 1.0, 1.0+, and 2.0)
