Subject: [patch 0/7 -mm] oom killer rewrite

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

To apply to mainline, download 2.6.33-rc7 and apply

	mm-clean-up-mm_counter.patch
	mm-avoid-false-sharing-of-mm_counter.patch
	mm-avoid-false_sharing-of-mm_counter-checkpatch-fixes.patch
	mm-count-swap-usage.patch
	mm-count-swap-usage-checkpatch-fixes.patch
	mm-introduce-dump_page-and-print-symbolic-flag-names.patch
	sysctl-clean-up-vm-related-variable-declarations.patch
	sysctl-clean-up-vm-related-variable-declarations-fix.patch
