I have reported this before, as did 0day, but I don't know if anyone
is fixing this:

https://lists.01.org/pipermail/kbuild-all/2017-October/038694.html

This is caused by commit 43b97bf59c69 ("MIPS: Allow __cpu_number_map
to be larger than NR_CPUS")

A harmless rework that Linus Walleij did apparently uncovered an
ancient bug. I'm
waiting for Linus to suggest a fix.

Caused by the new 128-bit arithmetic in ARM64, a fix has been submitted by the
original author.

endless stream of new dtc warnings, mostly valid. I have started
fixing them but at some point
gave up. Looking for help here.

Not sure, we discussed possible alternatives, but it looks like this
is not getting addressed before
4.15, so we may end up removing the deprecation warning to get a clean
4.15 build instead.

I have a patch, will send after some more testing.
