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

Yes, I broke it, sorry!

There's a fix queued in arm64/fixes/core already (04c4927359b1). Using a 
different toolchain is another option, since the one I'm currently using 
(gcc-linaro-7.2.1-2017.11) builds it just fine, which is how I managed 
to create this mess in the first place ;)

Thanks,
Robin.

Pull request to go out today. I forgot that arm64 fixes/core doesn't get
pulled into -next (maybe we should fix this).

Good to know that! Thanks for help.
