Merge tag 'v4.6-rc3' into drm-intel-next-queued

Linux 4.6-rc3

Backmerge requested by Chris Wilson to make his patches apply cleanly.
Tiny conflict in vmalloc.c with the (properly acked and all) patch in
drm-intel-next:

commit 4da56b99d99e5a7df2b7f11e87bfea935f909732
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Apr 4 14:46:42 2016 +0100

    mm/vmap: Add a notifier for when we run out of vmap address space

and Linus' tree.
