This looks like it's supporting SMP - is there some reason not to use
the localtimer support built into SMP, which also supports hotplug CPU
(the above doesn't because the local clockevents will be automatically
unregistered.)

As I know, to use the localtimer support, it needs to support PPI.
Unfortunately the MCT of S5PV310 supports SPI. For hotplug CPU, I'm looking
for the methods to register clockevents again at CPU hotplug-in.

We can avoid that - nothing forces you to use the PPI interrupt.
Just register your interrupt handler in the normal way.

There's really no need to reinvent the wheel.
