individual asm versions. The global lock is shared between the BIOS and
OS and thus cannot use our mutexes. It is defined in section 5.2.9.1 of
the ACPI specification.

on my part. The output asm looks correct with the previous commit in place
and it works on amd64, but on my laptop I got a spew of AE_BAD_PARAMETER
errors trying to unlock the acpi global lock.
and releasing ACPI global locks instead of (ab)using the pointers to those
locks as the constants. Also, rather than require that the address of
the lock be stored in a register, use a memory constraint allowing the
memory address to be used directly.
