Some change in permission_fault() for SMAP.  It also reduces
calls two callbacks to get CPL and RFLAGS in come cases, but it
has not any measurable performance change in tests (kernel build
in guest).

I am going to queue patches 1-4. The last one shouldn't really have any performance impact with static calls.
