Hi Ingo/Thomas,
Here are few cleanups around timer-core initialization. The first one is
suggested by Peter Zijlstra [1] and the other two make few more changes in order
to simplify it.
Please see if they look fine.

Peter Zijlstra (1):
timer: Allocate per-cpu tvec_base's statically
Viresh Kumar (2):
timer: Limit the scope of __tvec_bases to init_timers_cpu()
timer: Don't initialize tvec_base on hotplug

A delayed work to schedule vmstat_shepherd() is queued at periodic intervals for
internal working of vmstat core. This work and its timer end up waking an idle
cpu sometimes, as this always stays on CPU0.
Because we re-queue the work from its handler, idle_cpu() returns false and so
the timer (used by delayed work) never migrates to any other CPU.
This may not be the desired behavior always as waking up an idle CPU to queue
work on few other CPUs isn't good from power-consumption point of view.
In order to avoid waking up an idle core, we can replace schedule_delayed_work()
with a normal work plus a separate timer. The timer handler will then queue the
work after re-arming the timer. If the CPU was idle before the timer fired,
idle_cpu() will mostly return true and the next timer shall be migrated to a
non-idle CPU.
But the timer core has a limitation, when the timer is re-armed from its
handler, timer core disables migration of that timer to other cores. Details of
that limitation are present in kernel/time/timer.c:__mod_timer() routine.
Another simple yet effective solution can be to keep two timers with same
handler and keep toggling between them, so that the above limitation doesn't
hold true anymore.
This patch replaces schedule_delayed_work() with schedule_work() plus two
timers. After this, it was seen that the timer and its do get migrated to other
non-idle CPUs, when the local cpu is idle.
