This patchset is a rewrite of the out of memory killer to address several
issues that have been raised recently. The most notable change is a
complete rewrite of the badness heuristic that determines which task is
killed; the goal was to make it as simple and predictable as possible
while still addressing issues that plague the VM.

This patchset is based on mmotm-2010-02-05-15-06 because of the following
dependencies:

[patch 4/7] oom: badness heuristic rewrite:
mm-count-swap-usage.patch

[patch 5/7] oom: replace sysctls with quick mode:
sysctl-clean-up-vm-related-variable-delcarations.patch
