[PATCH -mm v2 00/11] pagewalk: standardize current users, move pmd locking, apply to mincore

[Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>]

This is ver.2 of page table walker patchset.

I move forward on this cleanup work, and added some improvement from the
previous version. Major changes are:
 - removed walk->skip which becomes removable due to refactoring existing
   users
 - commonalized the argments of entry handlers (pte|pmd|hugetlb)_entry()
   which allows us to use the same function as multiple handlers.

This patchset is based on mmotm-2014-05-21-16-57.

Branch: mmotm-2014-05-21-16-57/page_table_walker.v2

Thanks,
