SubjectRe: [PATCH] cpumask 5/10 rewrite cpumask.h - single bitmap based implementation

I don't see why user code needs to determine NR_CPUS exactly. Any
reasonable upper bound should work - reasonable meaning doesn't waste
too many unused words of memory.

It's not really NR_CPUS that users need - its a reasonably close upper
bound to the size of the space that sched_getaffinity() must be provided
they need. And your code does a pretty good job of providing that.
