Subject: Re: arm64: build is broken on next-20170609 with merge-commit
 9afca2c4e379 (arm64: allwinner: sun50i-a64: add dwmac-sun8i Ethernet
 driver)

[Yes, top posted :-)]

With the merge window approaching, this is just a reminder that this
merge problem still exists.  I assume that the sunxi tree will be
merged into the arm-soc tree before going to Linus.
