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

From: Thorsten Leemhuis

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 regressions@xxxxxxxxxxxxx). And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten
