perf counters: implement PERF_COUNT_TASK_CLOCK
Impact: add new perf-counter type The 'task clock' counter counts the amount of time a task is executing, in nanoseconds. It stops ticking when a task is scheduled out either due to it blocking, sleeping or it being preempted. This counter type is a Linux kernel based abstraction, it is available even if the hardware does not support native hardware performance counters. Signed-off-by: Ingo Molnar <mingo@elte.hu>
