Subject[PATCH 00/10] mm: pagewalk: huge page cleanups and VMA passing
From
Date
The hugetlbfs and THP support in the walk_page_range() code was
mostly an afterthought.

We also _tried_ to have the pagewalk code be concerned only with
page tables and *NOT* VMAs. We lost that battle since 80% of
the page walkers just pass the VMA along anyway.

This does a few cleanups and adds a new flavor of walker which
can be stupid^Wsimple and not have to be explicitly taught about
THP.
