Ingo, Thomas, Please pull the timers/cputime-fix-steal-v2 branch that can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git timers/cputime-fix-steal-v2 It's based on tip:timers/core. The patches are essentially unchanged since the last version (https://lkml.org/lkml/2014/3/6/376). I only added a small comment in 4/6 and acks from Rik. --- The main purpose of this set is to fix a bug on full dynticks configs where steal time accounting appears to be zero in /proc/stat even after a few seconds of competing guests running busy loops in a same host CPU. It's not a regression though as it was there since the beginning with full dynticks. So patch [4/6] ("cputime: Fix jiffies based cputime assumption on steal accounting") is the most important patch of the series. The rest is mostly preparatory work to fix the bug plus various cleanups.
