Ok, this is v2.
I left out the MF_COUNT_INCREASED changes as we need to have the
pages pinned when coming from madvise, otherwise we might be messing
with a page which belongs to someone else.

I ran several tests [1] [2] to make sure nothing is broken.

 @Andrew: Please, remove [3] from mmotm and linux-next and replace it
          with this one.

Thanks
