Subject: Linux 4.9: Reported regressions as of Sunday, 2016-11-20

Hi! Here is my fourth regression report for Linux 4.9. It lists 10
regressions I'm aware of. 6 of them are new; 11 got fixed (wow!)
since the last report -- that was two weeks ago, because I
didn't find any spare time to compile a report last Sunday :-/

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

There's a patch, acked by Riku Voipio, last version at
https://www.spinics.net/lists/linux-kbuild/msg13696.html
Michal: ping, does anything need to be done for merge?

Not fixed yet, that pull merely allowed per-arch asm/asm-prototypes.h,
you need to actually provide those files on affected archs; patches for
x86 and arm exist.

Fixed by commit 818f38c5b7c4 ("MIPS: Fix build of compressed image"). So this
is actually fixed since v4.9-rc4, but I only looked into this again today.

Thanks,

This is currently only fixed for powerpc. Fixes for x86 and ARM were
proposed but not merged, and all other architectures don't even have
a fix as far as I can tell.

It's only broken with CONFIG_MODVERSIONS=y though, and not all modules
are affected on all architectures, so a lot of testers have not noticed.
