Merge branch 'timers-nohz-for-linus' of git://git.kernel.org/pub/scm/…
…linux/kernel/git/tip/tip Pull timer updates from Ingo Molnar: "The main purpose is to fix a full dynticks bug related to virtualization, 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. The other commits are preparatory work to fix the bug and various cleanups" * 'timers-nohz-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: arch: Remove stub cputime.h headers sched: Remove needless round trip nsecs <-> tick conversion of steal time cputime: Fix jiffies based cputime assumption on steal accounting cputime: Bring cputime -> nsecs conversion cputime: Default implementation of nsecs -> cputime conversion cputime: Fix nsecs_to_cputime() return type cast
