This might add little value.

arm build sets failed on linux next 20200721.
The defconfig ( +config fragments ) builds PASS.
The tinyconfig and allnoconfig FAILED with gcc-8, gcc-9 and gcc-10.

Adding Linus and Ard to Cc as well.

Absolutely no point.

It was known about last night (see your irc scrollback - I mentioned it
to sfr). It was reported earlier this afternoon just after I dropped
the commit. It's now been reported again.

So, please ignore these reports.
