pudp_set_wrprotect and move_huge_pud helpers are only used when CONFIG_TRANSPARENT_HUGEPAGE is enabled. Similar to pmdp_set_wrprotect and move_huge_pmd_helpers use architecture override only if CONFIG_TRANSPARENT_HUGEPAGE is set Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> --- include/linux/pgtable.h | 2 ++ mm/mremap.c | 2 +- 2 files changed, 3 insertions(+), 1 deletion(-)
