Subject: [PATCH linux-next v3 1/4] time/sched_clock: Export sched_clock_register()

From: Chun-Hung Wu <[email protected]>

clocksource driver may use sched_clock_register()
to resigter itself as a sched_clock source.
Export it to support building such driver
as module, like timer-mediatek.c

Sorry for the late reply, I was traveling when I got your mail.

Thanks for your iterations on this series.
I'm ok with these, assuming the folks who maintain the timer-mediatek
driver don't have any more objections.

So for the first three patches:
