Hi,

This patch series are to select ARCH_HAS_FORTIFY_SOUCE on arm.
A lot of architectures already select ARCH_HAS_FORTIFY_SOURCE
to support CONFIG_FORTIFY_SOURCE that detects overflows at compile-time.
(6974f0c4555e ("include/linux/string.h:
add the option of fortified string.h functions)
ARM can be built and run with CONFIG_FORTIFY_SOURCE.

Additionally, modify vdso.c to remove compile-error that happens
when built arm kernel with CONFIG_FORTIFY_SOURCE.

Jinbum Park (2):
arm: mm: Define vdso_start, vdso_end as array
arm: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE
