[PATCH v3 00/10] perf: Avoid placing cpumask on the stack

[Dawei Li]

Hi all,

This is v3 of previous series on elimination of placing cpumask var on
stack.

Change since v2:
- Update commit message for patch[2-10]. [Mark] 
- Add Reviewed-by from Mark for patch[2-10].

Change since v1:
- Change from dynamic allocation to a temporary var free helper:
  cpumask_any_and_but().	[Mark]

- Some minor coding style improvements, reverse chrismas tree e.g.

- For cpumask_any_and_but() itself:
  - Moved to cpumask.h, just like other helpers.
  - Return value converted to unsigned int.
  - Remove EXPORT_SYMBOL, for obvious reason.

v1:
