hm, why was that added.

Michel, I seem to have confused myself over this series.  I saw a
report this morning which led me to drop
mm-accelerate-munlock-treatment-of-thp-pages.patch but now I can't find
that report and I'm wondering if I should have dropped
mm-accelerate-mm_populate-treatment-of-thp-pages.patch instead.

Given that and Sasha's new report I think I'll drop

mm-use-long-type-for-page-counts-in-mm_populate-and-get_user_pages.patch
mm-use-long-type-for-page-counts-in-mm_populate-and-get_user_pages-fix.patch
mm-use-long-type-for-page-counts-in-mm_populate-and-get_user_pages-fix-fix.patch
mm-accelerate-mm_populate-treatment-of-thp-pages.patch
mm-accelerate-munlock-treatment-of-thp-pages.patch

and let's start again?
