perf_counter: convert perf_resource_mutex to a spinlock
Now percpu counters can be initialized very early. But the init sequence uses mutex_lock(). Fortunately, perf_resource_mutex should be a spinlock anyway, so convert it. [ Impact: fix crash due to early init mutex use ] LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>
