Hi,

This series re-enables contiguous hugepage support for arm64. In v6,
I've addressed all the concerns raised on the previous version.

Notable changes in this version -

* Patch 4 - "Add break-before-make logic for contiguous entries"
  - added clear_flush() and use it in set_huge_pte_at()
  - Updated huge_ptep_clear_flush() to use clear_flush()
  - Track dirty bit based on returned value from get_clear_flush() in
    huge_ptep_set_access_flags()
  - Dropped Mark's reviewed-by (please re-apply if you're still happy
    with the patch)

All the dependent series ([2], [3]) for enabling contiguous hugepage
support have been merged in the previous cycle. Additionally, a patch
to clarify the semantics of huge_pte_offset() in generic code[6] is
currently in the -mm tree.

Previous postings can be found at [0], [1], [4], [5], [7].

The patches are based on v4.13-rc4. If there are no further comments
please consider merging for the next release cycle.

Thanks,
Punit
