description:
Switch NetBSD/news68k to using 8KB/page in kernel.
It slightly improves performance on NWS-1750D (MC68030 25MHz):
http://mail-index.NetBSD.org/port-m68k/2009/12/08/msg000204.html

MI m68k/pmap_motorola.c and other sources can handle both 4KB/8KB pages
(amiga and atari have used 8KB pages for many years) and there is
no binary compatibility issue on it.
(kernel modules might be affected but 5.99.29 was just two days ago)
