config: arm64-allmodconfig (attached as .config)
compiler: aarch64-linux-gnu-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
        # save the attached .config to linux build tree
        make.cross ARCH=arm64 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x39a80): Section mismatch in reference from the function memblock_next_valid_pfn() to the variable .meminit.data:$d
   The function memblock_next_valid_pfn() references
   the variable __meminitdata $d.
   This is often because memblock_next_valid_pfn lacks a __meminitdata
   annotation or the annotation of $d is wrong.
