[BUGFIX for 2.6.36][RESEND][PATCH 1/2] oom: remove totalpage normalization from oom_badness()

[KOSAKI Motohiro]

ok, this one got no objection except original patch author.
then, I'll push it to mainline. I'm glad that I who stabilization
developer have finished this work.

If you think this patch is slightly large, please run,
 % git diff a63d83f42^ mm/oom_kill.c
you'll understand this is minimal revert of unnecessary change.

Thanks.
