[0/3] Standardize kvm exit reason field

Message

Some utilities (e.g. kvm_stat) have the assumption that same filter
field "exit_reason" for kvm exit tracepoint. However, they're varied
on different architects. It can be fixed for the utilities to pick
different filter names, or standardize it to have unified name "exit_reason",
The series takes the second approach, suggested by Vitaly Kuznetsov.

I'm not sure which git tree this will go, so I have one separate patch
for each architect in case they are merged to different git tree.

  kvm/powerpc: Standardize kvm exit reason field
  kvm/aarch64: Standardize kvm exit reason field

Queued, thanks (patches 1-2).
