These are some miscellaneous code refactors around using cpumask
APIs. They are mainly aimed at code simplification.

Changes since v1:
- Dropped the changes done in xive_find_target_in_mask. Those changes are
  done by Yury Norov already.
- Collected the tags. Thanks to Yury Norov. 
- Added new patch to use cpumask_intersects instead of using
  temp_mask to achieve the same goal.
- Added new patch to print the warning when target CPU not found
  as discussed in [2]. This patch is kept separate since this adds
  a new warning in case of failure. So one may perceive it as functional
  change.

  powerpc: Use cpumask_next_wrap instead
  powerpc: Simplify cpumask api usage for cpuinfo display
  powerpc/perf: Use cpumask_intersects api for checking disable path
  powerpc/xive: Add warning if target CPU not found

Gentle Ping,
Still applies cleanly to today's tip master.

Do you have any comments on this? Do you want me to resend with yury's tag?
