[PATCH V2 0/2] mm/thp: Rename pmd_mknotpresent() as pmd_mkinvalid()
This series renames pmd_mknotpresent() as pmd_mkinvalid(). Before that it drops an existing pmd_mknotpresent() definition from powerpc platform which was never required as it defines it's pmdp_invalidate() through subscribing __HAVE_ARCH_PMDP_INVALIDATE. This does not create any functional change. This rename was suggested by Catalin during a previous discussion while we were trying to change
