[RFC GIT PULL] nohz: Full dynticks rq clock handling

[Frederic Weisbecker <fweisbec@gmail.com>]

Hi,

So this is the part that handles the rq clock on full dynticks CPUs.
May be some of the update_nohz_rq_clock() calls here could even
apply to mainline for dynticks idle CPUs.

There are still two known places I need to look into for which I had patches
in my nohz tree but I need to have a deeper look into these (make the patch
saner, check if the problem should be fixed in mainline instead, etc...):

* http://git.kernel.org/cgit/linux/kernel/git/frederic/linux-dynticks.git/commit/?h=3.9-rc1-nohz1&id=36ca34d0d4ba0a9589cf3054a7df9f0879ddd6c5
* http://git.kernel.org/cgit/linux/kernel/git/frederic/linux-dynticks.git/commit/?h=3.9-rc1-nohz1&id=9c3af3b4104682217b1f602acb4efbab563ccf59

But otherwise this patchset handles the big bulk of rq clock handling.

This can be pulled from:

Thanks.
