/facepalm

All that work to get rid of the darn thing, and then I forget to actually get rid
of it.

I also failed to remove the msrpm_offset declaration (and its size macro)

  #define MSRPM_OFFSETS	32
  extern u32 msrpm_offsets[MSRPM_OFFSETS] __read_mostly;

which are dead code as of "KVM: SVM: Manually recalc all MSR intercepts on userspace
MSR filter change".

Nice catch, and thank you!
