Thomas Gleixner 4ac13294e4 perf counters: protect them against CSTATE transitions ...

Impact: fix rare lost events problem

There are CPUs whose performance counters misbehave on CSTATE transitions,
so provide a way to just disable/enable them around deep idle methods.

(hw_perf_enable_all() is cheap on x86.)
