Merge tag 'remove-local-timers' of git://git.kernel.org/pub/scm/linux/kernel/git...

From Stephen Boyd:

Now that we have a generic arch hook for broadcast we can remove the
local timer API entirely. Doing so will reduce code in ARM core, reduce
the architecture dependencies of our timer drivers, and simplify the code
because we no longer go through an architecture layer that is essentially
a hotplug notifier.

* tag 'remove-local-timers' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm:
  ARM: smp: Remove local timer API
  clocksource: time-armada-370-xp: Divorce from local timer API
  clocksource: time-armada-370-xp: Fix sparse warning
  ARM: msm: Divorce msm_timer from local timer API
  ARM: PRIMA2: Divorce timer-marco from local timer API
  ARM: EXYNOS4: Divorce mct from local timer API
  ARM: OMAP2+: Divorce from local timer API
  ARM: smp_twd: Divorce smp_twd from local timer API
  ARM: smp: Remove duplicate dummy timer implementation

Resolved a large number of conflicts due to __cpuinit cleanups, etc.
