drivers/clocksource/time-armada-370-xp.c:217:13: warning: symbol
'armada_370_xp_timer_init' was not declared. Should it be static?
Also remove the __init marking in the prototype as it's
unnecessary and drop the init.h file.

Now that the TWD doesn't rely on the local timer API, OMAP can
stop selecting it in Kconfig and relying on the config option to
decide if it should call smp_twd functions.

Drop ARM's version of the dummy timer now that we have a generic
implementation in drivers/clocksource.

Separate the mct local timers from the local timer API. This will
allow us to remove ARM local timer support in the near future and
gets us closer to moving this driver to drivers/clocksource.

Actually, it's worse. From reading the co

I don't know if it's worth stable, seems that nobody has compiled XIP for

It seems we define the arch_spin_is_contended() macro but we don't
use it on SMP && PREEMPT kernels?
