Pull up following revision(s) (requested by tsutsui in ticket #1205):
sys/arch/x68k/x68k/machdep.c: revision 1.204 Restore fixes for PR/51663 lost in r1.195 (uvm_hotplug(9) merge). The kernel crashdump and savecore(8) on NetBSD/x68k have been broken (even without EXTNEDED_MEMORY) since NetBSD 8.0. Oops. Should be pulled up to netbsd-9 and netbsd-8.
