Hey all,

Previously, mTHP could only be mapped to PTEs where all entries were none.
With this change, PTEs within the range mapping the demand-zero page can
now be treated as `pte_none` and remapped to a new mTHP, providing more
opportunities to take advantage of mTHP.

Lance Yang (2):
  mm/mthp: add pte_range_none_or_zeropfn() helper
  mm/mthp: relax anon mTHP PTE Mapping restrictions
