- retire union cpu_info_pg
- allocate space for each cpu_info{} in pmap_bootstrap
- remap cpu0's space into the PA currently in CPUINFO_VA
- cpus[] becomes an array of pointers to cpu_info{}, easy to traverse
- only call kernel lock for IPL_VM interrupts (?  as implemented on
  x86 and sparc64)
- revert a minor part of locore.s:1.241
- in cpu_hatch(), set %sp to near the middle of the interrupt stack.
  we only need a %sp until we get to run an MI thread (own idlelwp or
  real code)
we still waste one page of space, but this gets SMP much closer to
actually working again.
fix a LOCKDEBUG problem from the previous: need to call pmap_kremove()
on a pre-existing mapping, before installing a new one.
