Ingo, Thomas,
Please pull the timers/cputime-fix-steal-v3 branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
timers/cputime-fix-steal-v3
Only the last patch changed to address Peterz concern on arch Kbuild
layout. This got sorted out by running the script from b119fa61d440f
to alpabetically sort the entries.
---
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.
Thanks,
Frederic
