I'm sorry I can't have enough review time in these days but the whole series
seems good to me.


BTW, how about trying to merge patch 1/21 -> 13or14/21 first ?
This series adds many changes to various place under /mm. So, step-by-step
merging will be better I think.
(Just says as this because I tend to split a long series of patch to 
 small sets of patches and merge them one by one to reduce my own maintainance cost.)

At final lock splitting, performance number should be in changelog.

Thanks,
