ACPI: ACPICA 20060608
Converted the locking mutex used for the ACPI hardware
to a spinlock. This change should eliminate all problems
caused by attempting to acquire a semaphore at interrupt
level, and it means that all ACPICA external interfaces
that directly access the ACPI hardware can be safely
called from interrupt level.
Fixed a regression introduced in 20060526 where the ACPI
device initialization could be prematurely aborted with
an AE_NOT_FOUND if a device did not have an optional
_INI method.
Fixed an IndexField issue where a write to the Data
Register should be limited in size to the AccessSize
(width) of the IndexField itself. (BZ 433, Fiodor Suietov)
Fixed problem reports (Valery Podrezov) integrated: - Allow
store of ThermalZone objects to Debug object.

Fixed problem reports (Fiodor Suietov) integrated: -
acpi_get_table_header() doesn't handle multiple instances
correctly (BZ 364)
Removed four global mutexes that were obsolete and were
no longer being used.
