send_guest_trap() cant be used to send anything other than an nmi or
mce, but you appear to be using it to try and send #PFs ?

Yes, this is wrong. I'll need to find right interface.


          {
          case MSR_TYPE_ARCH_CTRL:      /* MSR_P6_EVNTSEL[0,...] */
              mask = ~((1ull << 32) - 1);

It would be helpful not to mix large functional changes and code
cleanup.  While I appreciate the cleanup, could it be moved to a
different patch?  The same comment applies to several other patches as well.

I *think* this is the only instance of me doing this. I'll see if there are other places.
