# The change to pmdp_invalidate() to mark the pmd with _PAGE_INVALID # broke the synchronisation against lock free lookups, # __find_linux_pte()'s pmd_none() check no longer returns true for such # cases. # # Fix this by adding a check for this condition as well. # # Fixes: da7ad366b497 ("powerpc/mm/book3s: Update pmd_present to look at _PAGE_PRESENT bit") # Cc: stable@vger.kernel.org # v4.20+ # Suggested-by: Aneesh Kumar K.V #
