commit: cc591a392bd5a56d60f3955c9c8bd15e14477ffa [2/13] ARM: bugs: prepare processor bug infrastructure
config: arm-allmodconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout cc591a392bd5a56d60f3955c9c8bd15e14477ffa
        # save the attached .config to linux build tree

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x18ff0): Section mismatch in reference from the function check_bugs() to the function .init.text:check_writebuffer_bugs()
   The function check_bugs() references
   the function __init check_writebuffer_bugs().
   This is often because check_bugs lacks a __init
   annotation or the annotation of check_writebuffer_bugs is wrong.
