Re: [PATCH 2.6.21-rt2] PowerPC: decrementer clockevent driver

This scales with the number of processors since there is one
decrementer per core (is it per thread on SMT chips?
I don't know).

One per core.

No, each thread has its own decrementer, but the timebase is shared.

Argh, of course you're right, I'm reading the wrong ISA
version again. Sorry.
