Hi afzal,
[auto build test ERROR on linus/master]
[also build test ERROR on v4.10-rc4 next-20170119]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url: https://github.com/0day-ci/linux/commits/afzal-mohammed/ARM-mmu-decouple-VECTORS_BASE-from-Kconfig/20170119-171424
config: arm-stm32_defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 6.1.1-9) 6.1.1 20160705
