ARM: 8238/1: mm: Refine set_memory_* functions
set_memory_* functions have same implementation except memory attribute. This patch makes to use common function for these, and pull out the functions into arch/arm/mm/pageattr.c like arm64 did. It will reduce code size and enhance the readability. Signed-off-by: Jungseung Lee <js07.lee@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
