[PATCH V5 0/3] THP related cleanups

[Aneesh Kumar K.V]

Changes from V4:
* Folded patches in -mm
  mm-thp-split-out-pmd-collpase-flush-into-a-separate-functions-fix.patch
  mm-thp-split-out-pmd-collpase-flush-into-a-separate-functions-fix-2.patch
  mm-clarify-that-the-function-operateds-on-hugepage-pte-fix.patch
* Fix VM_BUG_ON on x86.
 the default implementation of pmdp_collapse_flush used the hugepage variant
 and hence can be called on pmd_t pointing to pgtable. This resulting in us
 hitting VM_BUG_ON in pmdp_clear_flush. Update powerpc/mm: Use generic version of pmdp_clear_flush
 to handle this.


NOTE: Can we get this tested on s390 ?

Aneesh Kumar K.V (3):
  mm/thp: Split out pmd collpase flush into a separate functions
  powerpc/mm: Use generic version of pmdp_clear_flush
  mm: Clarify that the function operates on hugepage pte
