src/sys/arch/mvme68k/mvme68k: pmap_bootstrap.c
Log Message:
Move physmem calculations before nptpage initialization.
Fixes mvme68k specific part of PR port-m68k/45915
(panic: pmap_enter_ptpage: can't get KPT page).
Reported and confirmed by Andrew Gillham on his MVME177:
http://mail-index.NetBSD.org/port-mvme68k/2013/09/17/msg000082.html
Should be pulled up to all netbsd-6 branches.
