True, but as I replied to Kamezawa in the other thread, these
architectures are still dependent on generic implementations of
account_{system,user}_time() which feed to per-process and system-wide
accounting. And this is where we have hooks for per-cgroup accounting.
So I don't see why we need to handle these archs specially. Do I miss
something ?

Bharata.
