Ingo,
Please pull the timers/core-v2 branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
timers/core-v2
It's a rebase of the previous pull request against 3.13-rc2 which addresses
your reviews:
* Fix build error with tick_check_nohz() off case
* Refine changelog of "posix-timers: Fix full dynticks CPUs kick on timer
rescheduling"
to make it clearer that it's a bug fix and not just an optimization.
Also add more overall details in the changelog about the description of the
issue.
* Rename tick_check_nohz() and tick_check_oneshot_broadcast() to extend with
*_this_cpu()
suffix. Note that I left functions that use *_idle_* based naming as is
because idle
itself is a per cpu notion already. Now I can still extend these functions as
well
in a delta if you want, although IMHO I fear that would uglify the code more
than helping.

Here is a summary of the overall changes against tip:timers/core :
* Optimizations and cleanups on the use of per CPU APIs to improve code
readability,
performance and debuggability in the nohz subsystem;
* Rename some functions to extend with *_this_cpu() suffix for clarity
* Refine the naming of some context tracking subsystem state accessors
* Optimize posix cpu timer by sparing stub workqueue queue with full dynticks
off case
* Trivial spelling fix by Paul Gortmaker
* 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).
Let me know if you find any issue.
Thanks,
Frederic
