New Revision: 237933
URL: http://svn.freebsd.org/changeset/base/237933

Log:
  Fire up our APs as soon as we kick the scheduler. We've woken them
  a long time back anyway, so they've been sitting idle for long enough.
  More importantly: the Altix PROM has assigned interrupts to CPUs and
  having our APs on hold means that we can't handle inteerupts that go
  to CPUs other than the APs -- this happens when we're doing interrupt
  based configuration (SI_SUB_INT_CONFIG_HOOKS).
  
  On NUMA machines like the Altix, it's infinitely better to have each
  brick probe and attach its own devices, so waking the APs sooner is
  generally a good idea. This is but a small step towards full SMP
  booting though...
