It is the intention that XSM would subsume ACM with the functionality
that ACM provides being in an ACM-specific XSM module. In Xen itself, it
is like that now. The ACM code is in the ACM module.

There still needs to be some thought given to what the correct user-
space interfaces should be. The current implementation uses the existing
ACM interfaces. There are different implementations of the functions
behind those interfaces for each XSM module. Which set of functions is
used depends on which XSM module has been installed.
