Merge branch 'timers/core-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into timers/core
Pull dynticks updates from Frederic Weisbecker:
* Fix a bug where posix cpu timers requeued due to interval got ignored on full
dynticks CPUs (not a regression though as it only impacts full dynticks and the
bug is there since we merged full dynticks).
* Optimizations and cleanups on the use of per CPU APIs to improve code readability,
performance and debuggability in the nohz subsystem;
* Optimize posix cpu timer by sparing stub workqueue queue with full dynticks off case
* Rename some functions to extend with *_this_cpu() suffix for clarity
* Refine the naming of some context tracking subsystem state accessors
* Trivial spelling fix by Paul Gortmaker
