This a set of misc ppc arch specific code improvements/optimizations.
Although there exists similar instances for potential improvements in
the legacy ppc code, however, that can be taken up later as well.

Harsh Prateek Bora (6):
  target/ppc: use locally stored msr and avoid indirect access
  target/ppc: optimize hreg_compute_pmu_hflags_value
  target/ppc: optimize hreg_compute_pmu_hflags_value
  target/ppc: optimize p9 exception handling routines
  target/ppc: reduce duplicate code between init_proc_POWER{9,10}
  target/ppc: redue code duplication across Power9/10 init code
