Comment(by bonefish):

 Not that I think it makes a difference in this case, but is there a reason
 why the map_physical_memory() call in AcpiOsMapMemory() uses
 B_ANY_KERNEL_BLOCK_ADDRESS? The semantics of this address specification is
 to align the area base address to the size of the area, also requiring a
 power of 2 size. Since the documentation of AcpiOsMapMemory() doesn't
 mention any special mapping requirements or properties of the arguments,
 this doesn't seem right.
