[PATCH 1/4] ARM: mmu: decouple VECTORS_BASE from Kconfig

[kbuild test robot]

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
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=arm 

Note: the linux-review/afzal-mohammed/ARM-mmu-decouple-VECTORS_BASE-from-Kconfig/20170119-171424 HEAD dd110acc21d40c8f50374de1e500a091d14f29c8 builds fine.
      It only hurts bisectibility.
