I'm at ce38207f161513ee3d2bd3860489f07ebe65bc78, which is already
broken, and first broken commit by Linus.

Can't revert that easily.

This can be reverted. Lets try. Did not help.

Commit older than this one fails, IIRC.

Its definitely caused by something merged here:

commit ce38207f161513ee3d2bd3860489f07ebe65bc78
Merge: a9042de 995c6a7
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date:   Wed Dec 14 11:14:28 2016 -0800

So it should be easy to find out..

Best regards,
								Pavel
