Following discussions on the LKML few months ago:


we need to adjust the LPAE pmd_mknotpresent() so that it does not clash
with the pmd_none() definition (IOW, we should allow !pmd_none() &&
!pmd_present() after pmd_mknotpresent()). This requires that
pmd_present() checks the L_PMD_SECT_VALID bit instead of a non-zero
value (similar commit for arm64: 5bb1cc0ff9a6 "arm64: Ensure
pmd_present() returns false after pmd_mknotpresent()")

Steve Capper (1):
  ARM: mm: Fix definition of pmd_mknotpresent

Will Deacon (1):
  ARM: mm: ensure pmd_present only checks the valid bit
