Very low-priority comment (I looked at the patch at the time it was
posted to stable@). Nice thing about the patch is that it presumably
identifies all the places that depend on the wideness of the cpu
mask. Would it make sense to abstract the cpumask operations with
some macros to not repeat the search for the places when 64 will
be too narrow again ?
