[PATCH 0/2] mm/thp: Rename pmd_mknotpresent() as pmd_mknotvalid()
This series renames pmd_mknotpresent() as pmd_mknotvalid(). 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

[PATCH 2/2] mm/thp: Rename pmd_mknotpresent() as pmd_mknotvalid()
pmd_present() is expected to test positive after pmdp_mknotpresent() as the
PMD entry still points to a valid huge page in memory. pmdp_mknotpresent()
implies that given PMD entry is just invalidated from MMU perspective while
still holding on to pmd_page() referred valid huge page thus also clearing
pmd_present() test. This creates the following situation which i...
