Something is wrong with drm/i915 (I guess). I had a terrible memleak on Xorg
when using mplayer using more and more RAM, and then the system is swapping
itself to death.
I'm using a openSUSE 13.1 (x86_64) on a Baytrail J1900 (this is Intel HD
Gen7).
Thank you for reporting, Thomas. Can you please confirm that this is
actually a regression in 3.16.7-ckt4 (i.e., that you can't reproduce
it in 3.16.7-ckt3)? If so, is it possible to bisecting it?
3.16.7-ckt3 was fine for me.
I tried to revert the drm/i915 patches in the review branch, and I got lucky
with (only) reverting cb58c663d940a "drm/i915: Disallow pin ioctl completely
for kms drivers".
No clue, why reverting these few lines helps, but then I have no memleak.

Thank a lot for narrowing this down, Thomas! The text in that commit
(upstream commit d472fcc8379c) may actually provide an hint for this
issue. It asks backporters to make sure they include both

drm/i915: Evict CS TLBs between batches
For some reason, this second commit (which was tagged for stable!)
isn't in 3.16, and I completely missed that.
Would you be able to verify that adding this commit (backport attached
bellow) fixes the issue?
Mh, no, sorry, that doesn't fix it. Very fast memleak with /usr/bin/X.
I used linux-3.16.y-review (with no reverts) + your patch from previous
mail.
