Do you have a test case for this? Since the kernel currently
is missing support for MSS read/write operations, I guess that
there should also be a bug report so we don't forget to fix
this in the kernel again.

Your patch looks good, except for the broken use of 'volatile'
(which doesn't prevent mmio accesses from getting moved outside
of spinlocks), but we should probably clean that up all at once,
since libspe2 still does it this way everywhere in the code.
