All errors (new ones prefixed by >>):

Thanks for input, the issue does exist (as introduced by
"drm/amdgpu/display: Enable DCN in DC"), so the report like
https://lists.01.org/pipermail/kbuild-all/2017-May/033857.html
does make sense.
It's because some DC Makefiles hardcode -msse and other compiler flags
which aren't supported on all architectures.
DC folks, please fix this, either by only adding flags on architectures
where they're supported, or by preventing the corresponding code from
getting built on architectures where they're not supported.
Ah, yes that's indeed an issue.
But please at least fix the bisect or otherwise the wrong people get
those mails and wonder about the error messages.
I just submitted a fix for this: "drm/amd/display: Limit DCN to x86 arch"
It seems to do the trick but I've never really dealt with multiple
architectures before. Would appreciate if someone more knowledgeable
than myself reviews this.
Essentially I'm blocking DCN code for non-x86 architectures for now.
Thanks,
Harry
Christian.
