[PATCH 0/2] mm/thp: Rename pmd_mknotpresent() as pmd_mknotvalid()

drops an existing pmd_mknotpresent() definition from powerpc platform which
was never required as it defines it's pmdp_invalidate() through subscribing

functionality more accurately while changing the above mentioned situation
as follows. This does not create any functional change.
[pmd_present(pmd_mknotvalid(pmd)) = true]
