Revision 971ee28cbd1ccd87b3164facd9359a534c1d2892 authored by Peter Zijlstra on 28 June 2013, 09:18:53 UTC, committed by Ingo Molnar on 12 July 2013, 11:52:58 UTC
David reported that the HRTICK sched feature was borken; which was enough
motivation for me to finally fix it ;-)

We should not allow hrtimer code to do softirq wakeups while holding scheduler
locks. The hrtimer code only needs this when we accidentally try to program an
expired time. We don't much care about those anyway since we have the regular
tick to fall back to.
