[ACPI] ACPICA 20050902

Fixed a problem with the internal Owner ID allocation and
deallocation mechanisms for control method execution and
recursive method invocation.  This should eliminate the
OWNER_ID_LIMIT exceptions and "Invalid OwnerId" messages
seen on some systems.  Recursive method invocation depth
is currently limited to 255.  (Alexey Starikovskiy)

http://bugzilla.kernel.org/show_bug.cgi?id=4892

Completely eliminated all vestiges of support for the
"module-level executable code" until this support is
fully implemented and debugged.  This should eliminate the
NO_RETURN_VALUE exceptions seen during table load on some
systems that invoke this support.

http://bugzilla.kernel.org/show_bug.cgi?id=5162

Fixed a problem within the resource manager code where
the transaction flags for a 64-bit address descriptor were
handled incorrectly in the type-specific flag byte.

Consolidated duplicate code within the address descriptor
resource manager code, reducing overall subsystem code size.
