This commit is a combination of Stephan's original one and John's style
fix on mp_machdep.c. I have tested the patch on various SMP boxes running
RELENG_5_3 (4*P3 Xeon, 2*P4 w/HTT, 2*P4 Xeon configurations) under heavy
load for a couple of weeks, so commit on behalf of Stephan when he is
on vacation.
RELENG_5_3 candidate after settle time.
