In the end I also implemented this incremental to your change: http://git.kernel.org/cgit/linux/kernel/git/andrea/aa.git/commit/?h=userfault&id=c308fc81b0a9c53c11b33331ad00d8e5b9763e60 Let me know if you're ok with it. The commit header explains more why I think the bits below PAGE_SHIFT of the fault address aren't interesting but why I did this change anyway. After reviewing this last change I think it's time to make a proper submit and it's polished enough for merging in -mm after proper review of the full patchset.
