Subject: x86: perf: Use hrtimer_start()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=514c2304b4574dae28c3d7c0ad6b9cf296994140;p=linux-beck.git

x86: perf: Use hrtimer_start()

hrtimer_start() does not longer defer already expired timers to the
softirq. Get rid of the __hrtimer_start_range_ns() invocation.
