From: "Jason J. Herne" <jjhe...@us.ibm.com>
Modify kvm_arch_get_registers anf kvm_arch_put_registers interfaces such
that they accept a register bitmap parameter. Also modify the only caller of
kvm_arch_get_registers such that it passes an appropriate bitmap. The idea here
is that, for all currently existing calls we want to do nothing different.
