      [ACPI] ACPICA 20050114 from Bob Moore · fa6c3e73
      Len Brown authored 
      Added 2005 copyright to all ACPICA files.

Fixed an issue with the String-to-Buffer conversion code
where the string null terminator was not included in the
buffer after conversion, but there is existing ASL that
assumes the string null terminator is included. This is the
root of the ACPI_AML_BUFFER_LIMIT regression. This problem
was introduced in the previous version when the code was
updated to correctly set the converted buffer size as per
the ACPI specification. The ACPI spec is ambiguous and
will be updated to specify that the null terminator must
be included in the converted buffer. This also affects
the ToBuffer() ASL operator.

Fixed a problem with the Mid() ASL/AML operator where it
did not work correctly on Buffer objects. Newly created
sub-buffers were not being marked as initialized.

Fixed a problem in acpi_tb_find_table where incorrect string
compares were performed on the oem_id and oem_table_d table
header fields.  These fields are not null terminated,
so strncmp is now used instead of strcmp.

Implemented a restriction on the Store() ASL/AML operator
to align the behavior with the ACPI specification.
Previously, any object could be used as the source
operand.  Now, the only objects that may be used are
Integers, Buffers, Strings, Packages, Object References,
and DDB Handles.  As acpi_gbl_enable_interpreter_slack
is FALSE by default, "acpi=strict" is needed to enable
this check.

Enhanced the optional "implicit return" support to allow
an implicit return value from methods that are invoked
externally via the AcpiEvaluateObject interface.  This
enables implicit returns from the _STA and _INI methods,
for example.

Changed the Revision() ASL/AML operator to return the
current version of the AML interpreter, in the YYYYMMDD
format. Previously, it incorrectly returned the supported
ACPI version (This is the function of the _REV method).

Updated the _REV predefined method to return the currently
supported version of ACPI, now 3.

      [ACPI] Make the bm_activity depend on "jiffies", instead of numbers · caf866a0

      of the check being called. This means bus mastering activity
is assumed if bm_check isn't called; and multiple calls during
one jiffy will be |='ed.
