[PATCH 00/38] tick cleanups and bugfixes

[Viresh Kumar]

Hi Thomas,

These are separate cleanups from the timers/hrtimers ones I did. I was waiting
for the merge window to close in order to send these and by the time it
happened, I got a long pending list.

These are mostly cleanups, reorders for better readability or efficiency, and
few bugfixes.

I have pushed these here as well:

git://git.linaro.org/people/viresh.kumar/linux.git tick-cleanups

They will be tested by kbuild bot also starting from tonight.
