[PATCH V2 2/2] mm/thp: Rename pmd_mknotpresent() as pmd_mkinvalid()

2020-04-21 Thread Anshuman Khandual
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 cleari

[PATCH V2 0/2] mm/thp: Rename pmd_mknotpresent() as pmd_mkinvalid()

2020-04-21 Thread Anshuman Khandual
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.
