Completed a new design and implementation for the ACPI Global Lock support. On the OS side, the global lock is now treated as a standard AML mutex. Previously, multiple OS threads could acquire the global lock simultaneously, but this could cause the BIOS to be starved by the lock in cases such as the Embedded Controller driver, where there is a tight coupling between the OS and the BIOS.
