perf/core: Mark hrtimers to expire in hard interrupt context
To guarantee that the multiplexing mechanism and the hrtimer driven events
work on PREEMPT_RT enabled kernels it's required that the related hrtimers
expire in hard interrupt context. Mark them so PREEMPT_RT kernels wont
defer them to soft interrupt context.
No functional change.
[ tglx: Split out of larger combo patch. Added changelog ]
