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.

Based on tip/master at: (dffc5753ba4c "Merge branch into tip/master: 'timers/clocksource'")

  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
