Normal wake ups (like clock_nanosleep()) which are performed by normal
users can easily lead to 2ms latency spikes if (enough) hrtimer wakeups
are synchronized.
This patch moves all hrtimers wakeups to the softirq queue unless the
caller has a RT priority.

Normal wake ups (like clock_nanosleep()) which are performed by normal
users can easily lead to 2ms latency spikes if (enough) hrtimer wakeups
are synchronized.
This patch moves all hrtimers wakeups to the softirq queue unless the
caller has a RT priority.
