[PATCH 0/3] Fix compaction about mlocked pages

[Minchan Kim]

This patch's goal is to enable mlocked page migration.
The compaction can migrate mlocked page to get a contiguous memory unlike lumpy.

During making this patch, I found my silly bug which
[1/3] which fixes it.
[2/3] enables compaction of mlocked.
[3/3] enhance the accouting of compaction.

Frankly speaking, each patch is orthogonal but I send it by thread as I found them during
making patch on mlocked page compaction.

This patch series appears to be a resend of stuff I already have.

Given the various concerns which were voiced during review of
mm-compaction-compact-unevictable-pages.patch and the uncertainty of
the overall usefulness of the feature, I'm inclined to drop

mm-compaction-compact-unevictable-pages.patch
mm-compaction-compact-unevictable-pages-checkpatch-fixes.patch
mm-compaction-accounting-fix.patch

for now, OK?

It's okay on mm-compaction-compact-unevictable-pages.patch.
On mm-compaction-accounting-fix.patch, we still need it but I need to
change title as Mel commented out and I will send further patche which
changes stat names(https://lkml.org/lkml/2011/9/2/3) with it. So let's
drop it all.
I will resend further patches after rc-1.

Thanks, Andrew.
