xtraeme 32b7185652 MSR read and write IPI handlers for x86. A MSR will be read or written
in all CPUs available in the system. This adds another member
to struct cpu_info, ci_msr_rvalue; it will contain the value of the MSR
in a previous operation.

Tested with clockmod in UP and SMP by me, tested with est in SMP
by Daniel Carosone and Michael Van Elst.

Ok'ed by Andrew Doran and Matthew R. Green.
