[PATCH 0/3] Patches focus on clocksource_calc_mult_shift()

[Yong Zhang]

Hi Thomas/John,

When I was tring to apply commit d65670a7 to old kernel, I found
it's hard to apply, the reason is we only provide
clockevents_calc_mult_shift() for a period of time. And going
through the latest kernel, there is still the user of that
function. So I think we still need the ->maxadj tweak in
clockevents_calc_mult_shift(), this is the aim of patch#1.

And to loose the burden of you, I convert the only user of
clockevents_calc_mult_shift()/clocksource_register() to
clocksour_register_hz() (patch#2), and then get rid of
clockevents_calc_mult_shift() (patch#3).

IMHO, patch#1 will be more conservative and safe, and patch#3
is a little aggressive. I will let you decide to pick which one ;-)

Thanks,
Yong
