commit: 5615742edc64c99bbdec5e98bf9d9d872756d99c [1/1] efi/libstub: arm*: Pass latest memory map to the kernel
config: arm-multi_v7_defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:

        git checkout 5615742edc64c99bbdec5e98bf9d9d872756d99c
        # save the attached .config to linux build tree
