  log: |
    - use _MAXNCPU instead of 4
    - convert xpmsg_lock from a simplelock to a kmutex
    - don't wait for sparc_noop IPI calls
    - remove xmpsg_func's "retval" parameter and usage
    - remove the IPI at high IPL message
    - rework cpu_attach() a bunch, refactoring calls to getcpuinfo() and setting
      of cpi, and split most of the non-boot CPU handling into a new function
    - make CPU_INFO_FOREACH() work whether modular or not
    - move the MP cpu_info pages earlier
    - move a few things in cpu.c around to colsolidate the MP code together
    - remove useless if (cpus == NULL) tests -- cpus is an array now

    with these changes, and an additional change to crazyintr() to not printf(),
    i can get to single user shell on my SS20 again.  i can run a fwe commands
    but some of them cause hangs.  "ps auxw" works, but "top -b" does not.

    tested in UP LOCKDEBUG/DEBUG/DIAGNOSTIC kernel as well.
    MP kernel with only cpu0 configured panics starting /sbin/init.
    have not yet tested on a real UP machine.
