You do realise that it's pointless having local timers on non-SMP hardware.
On such hardware, you have a single timer instead.

You're also aware I assume that local timers are different from the global
timer itself, and require to have additional callbacks for broadcasting
the global timer tick?

There is a reason why local timers _use_ the common local timer clock event
stuff.
