xen panic

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
build from 202005272200Z panics on Xen, on both i386 and amd64 but for
different reasons: http://www-soc.lip6.fr/~bouyer/NetBSD-tests/xen/HEAD/

i386 fails early at boot with:
[   1.0000000] panic: kernel diagnostic assertion "!*zpte" failed: file "/home/source/ab/HEAD/src/sys/arch/x86/x86/pmap.c", line 3832 pmap_zero_page: lock botch

amd64 can boot and run tests, but panics with:

Any idea what could have changed to cause this ?
