cpumask: remove cpumask allocation from idle_balance
Impact: fix circular locking Steven reports a circular locking from alloc_cpumask_var doing a wakeup. We get rid of this using the tried-and-true technique of using a per-cpu cpumask_var_t rather than doing an alloc every time. Simpler and more robust than a rare, implicit allocation within an atomic codepath.
