Pull up following revision(s) (requested by mrg in ticket #733):
sys/arch/amd64/include/vmparam.h: revision 1.44

sys/arch/sparc64/include/vmparam.h: revision 1.38
bump PAGER_MAP_DEFAULT_SIZE to 512MB. this should allow more
concurrent IOs to be possible, and i'm unable to see pager_map
contention any more.
other larger platforms should probably do this too.
ok chs@.
Remove superfluous word in comment. Noted by Geoff Wing.
Bump PAGER_MAP_DEFAULT_SIZE to 512 MB (like amd64 recently did).
