Hi all, This is v2 of [1] and [2] which basically eliminate cpumask var allocation on stack for perf subsystem. 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.
