In the MP case,
do not attempt to pmap_tlb_shootdown() after a pmap_kenter_ma() during
boot. pmap_tlb_shootdown() assumes post boot. Instead invalidate the
entry on the local CPU only.
XXX: to DTRT, probably this assumption needs re-examination.
XXX: The tradeoff is a (predicted) single word size comparison
      penalty, so perhaps a decision needs performance stats.
xen dom0 SMP is now bootable again.
--
add the 'options MULTIPROCESSOR' in respective configs, but mark them
experimental - and thus disabled by default.
