[PATCH] libmm patches after fixups

Does the high level score interface need to include
"_Memory_management_Initialize"? Is MMU/MPU initialization only going
to be invoked in low-level BSP startup code?

The other primary issue I see (other than the hard-coded values in the
tests) is the use of a global SMP lock. I don't know if that is the
right way we want to use locks, or if the lock should be encapsulated
inside of some kind of MM structure (even if that structure is only a
wrapper for the lock).
