[PATCH v2 0/3] softdirty fix and write notification cleanup

[Peter Feiner <pfeiner@xxxxxxxxxx>]

Here's the new patch that uses Kirill's approach of setting write
notifications on the VMA. I also included write notification cleanups and
fixes per our discussion.

Peter Feiner (3):
  mm: softdirty: enable write notifications on VMAs after VM_SOFTDIRTY
    cleared
  mm: mprotect: preserve special page protection bits
  mm: mmap: cleanup code that preserves special vm_page_prot bits
