Subject: mm: fix ptep_modify_* for no-MMU systems
From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
Fixes build problem:
the functions added to asm-generic/pgtable.h are only used by
mm/mprotect.c (a MMU-only file), but they were not added inside of the
CONFIG_MMU ifdef block. since the functions rely on things inside of
CONFIG_MMU (the lines just above in pgtable.h), we get build failure
on all no-mmu setups:
