Make use of for_each_cpu_mask() macro to simplify and optimize a couple of
sparc64 per-CPU loops.

Optimize a bit of cpumask code for asm-i386/mach-es7000

Convert physids_complement() to use both args in the files
include/asm-i386/mpspec.h, include/asm-x86_64/mpspec.h.

Remove cpumask hack from asm-x86_64/topology.h routine pcibus_to_cpumask().

Clarify and slightly optimize several cpumask manipulations in kernel/sched.c
