  Log:
  Implement an all-CPU shootdown-style rendezvous facility.  This allows
  the caller to specify a function to be guarded between an entry and exit
  barrier, as well as pre- and post-barrier functions.
  
  The primary use for this function is synchronised update of per-cpu private
  data.  The implementation is almost (but not quite) MI; with a better
  mechanism for masking per-CPU interrupts it could probably be hoisted.
