1. disallow changing the SIMD mode when CPUs have been created.
it allowed userspace to corrupt kernel memory
2. Fix vCPU lookup. Until now the vCPU number equals the vCPU id. Some
kernel code places relied on that. This might
a: cause guest failures
b: allow userspace to corrupt kernel memory
3. Fencing of the PFMF instruction should use the guest facilities
and not the host facilities.
