ACPI: ACPICA 20060512

Replaced the acpi_os_queue_for_execution() with a new
interface named acpi_os_execute(). The major difference is
that the new interface does not have a Priority parameter,
this appeared to be useless and has been replaced by
a Type parameter. The Type tells the OS what type of
execution is being requested, such as global lock handler,
notify handler, GPE handler, etc. This allows the host
to queue and execute the request as appropriate for the
request type, possibly using different work queues and
different priorities for the various request types. This
enables fixes for multithreading deadlock problems such as

(Alexey Starikovskiy and Bob Moore)

Fixed a possible memory leak associated with the
support for the so-called "implicit return" ACPI
extension. Reported by FreeBSD  (Fiodor Suietov)
http://bugzilla.kernel.org/show_bug.cgi?id=6514

Fixed a problem with the Load() operator where a table
load from an operation region could overwrite an internal
table buffer by up to 7 bytes and cause alignment faults
on IPF systems. (With assistance from Luming Yu)
