SubjectRe: [PATCH][2.5] fix for_each_cpu compilation on UP
From said:

> Please apply

Could you elaborate on the purpose of this a bit? for_each_cpu() is only used
by the voyager subarch on x86 to traverse sparse CPU bitmaps efficiently in
critical path code. It has no other use in x86 SMP because all other
subarch's tend to compact the CPU bitmap much more.

If there are other uses for the construct, it should probably be put in bitops
and become for_each_bit(i, mask)
