Build failure on arm64 defconfig for linux-next recently

[Shawn Lin]

Hi folks,

I failed to build the arm64 kernel for linux-20180222 and I confirm it
works for linux-20180206. It seems there was some patches for head.S
got merged. Is it a known issue? Or a fix is coming?

make ARCH=arm64 defconfig

make 
CROSS_COMPILE=gcc-linaro-6.3.1-aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- 
  ARCH=arm64 -j32
