Changes in v7 - * Patch 4 - "Add break-before-make logic for contiguous entries" - get_clear_flush() - unconditionally clear the ptes (even if they are not present). This is to bring huge_ptep_get_and_clear() in line with generic implementation. - get_clear_flush() - Only flush the TLBs if the cleared entry was valid. - huge_ptep_set_wrprotect() - simplified based on Catalin's feedback. * Patch 6 - "Override huge_pte_clear() to support" - Address compile warnings due to non-existence of certain levels of the page table when using 16 and 64k pages. 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-rc6. If there are no further comments please consider merging for the next release cycle.
