I'd say it's a practical problem that users run into and hence it's a
regression. Sure, in this case it hits only those that compile kernels
themselves; but those are users, too, and we don't want to scare them
away with things that suddenly stop working.

IOW: I'll include it in this weeks report.

Ciao, Thorsten

Do build regressions count?

Because I was trying to fix an obscure build issue in arch/mips, choose
a random configuration that should hit that issue, and promptly ran
into
https://lkml.kernel.org/r/<201610301405.k82kqqw0%25fengguang...@intel.com>
The same configuration does build under v4.8, I tested that of course.

(Side note: I had to manually insert "25" after "%" to get this to
work. Should Intel fix its mail setup, or should lkml.kernel.org learn
to escape "%"?)

Thanks,

These two should hopefully be fixed as of today in current -git.

I think this was fixed Friday by the merge of the PAT regression fixes
from DaveA (merge commit .bdb520845b57)

This breaks framebuffer console on ppc64 I've been told as well, I
heard...

I'm at KS now, hard to get you more details, but there's something
fishy here either with the commit or with something we do on ppc with
fbdev that this commit breaks.

Cheers,
Ben.
