When XPC is being shutdown (i.e., rmmod, reboot) it doesn't ensure that
other partitions with whom it was connected have completely disengaged
from any attempt at cross-partition memory references. This can lead to
MCAs in any of these other partitions when the partition is reset.

Gcc4 doesn't like volatile casts as lvalues. Make the structure members
volatile instead.

This patch contains the bits to make the XPC code use the uncached
allocator rather than calling into the mspec driver. It also includes the
mspec.h header which is required to build the XPC modules.
