Hi! Here is my second regression report for Linux 4.9. It lists 14
regressions I'm aware of. 4 of them are new; 3 got fixed since last weeks report.
As always: Are you aware of any other regressions? Then please let me
know (simply CC [email protected]). And please tell me if there
is anything in the report that shouldn't be there.
Ciao, Thorsten

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.

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)

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%[email protected]>
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,
Paul Bolle

That's a good question.

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
