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 ?

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
