SubjectRe: [PATCH] Simplified scalable cpu bitmasks
From
   From: Rusty Russell <rusty@rustcorp.com.au>

This changes bitmap_member to the more logical DECLARE_BITMAP, then
uses it for cpu_online_map (ie. cpu_online_map is now an unsigned long
array).

Compiles and boots: Dave, how's this?

I'm ok with this for now.

I suspect that once you start using NR_CPUS in the range of 1024 or so
you want to allow the port do things like "use a pointer for cpuset_t
and NULL means CPU_MASK_ALL"

Or maybe not :-) we'll see.
