SVN rev 212559 on 2010-09-13 15:36:42Z by nwhitehorn
Fix a subtle bug uncovered by the recent one-shot timer import in which
any spin locks acquired between the enabling of interrupts in
machdep_ap_bootstrap() and the invocation of the scheduler would fail to
have interrupts disabled due to the fake spinlock already held by the
idle thread. sched_throw(NULL) will enable interrupts by itself when
exiting this spinlock, so just let it do that and don't enable interrupts
here.
