Subject: Linux 4.9: Reported regressions as of Sunday, 2016-10-23

Hi! Here is my first regression report for Linux 4.9. It lists 14
regressions I'm aware of. 
 
As always: Are you aware of any other regressions? Then please let me
know (simply CC regressions@...mhuis.info). And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten

P.S.: I ran out of time today (I really need to automate some things, 
but I do not find time for it…; and some of the regression tracking work 
simply can not be automated :/) and could not make it completely 
through my backlog. That's why I likely missed lots of regressions 
that were reported during the merge window and remain unfixed as of now 
:-/ Let me know about those, please.
