["Cherry G. Mathew" <cherry%netbsd.org@localhost>]

Module Name:    src
Committed By:   cherry
Date:           Mon Dec 26 08:53:11 UTC 2016

Modified Files:
        src/sys/arch/xen/x86: xen_pmap.c

Log Message:
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.
