Scott Wood d742aa152f powerpc/booke: Only check for hugetlb in flush if vma != NULL ... And in flush_hugetlb_page(), don't check whether vma is NULL after we've already dereferenced it. This was found by Dan using static analysis as described here: https://lists.ozlabs.org/pipermail/linuxppc-dev/2013-November/113161.html We currently get away with this because the callers that currently pass NULL for vma seem to be 32-bit-only (e.g. highmem, and CONFIG_DEBUG_PGALLOC in pgtable_32.c) Hugetlb is currently 64-bit only, so we never saw a NULL vma here.
