Indeed, I was also confused by the diffstat once noticed it after the
patches were sent out. And yes, I missed to git-add the
panfrost_gem_shrinker.c by accident. Good catch, thank you! I'll correct
it in in the v3.

Meanwhile, will be great if you or somebody else could test this
Panfrost patch. I don't have any h/w with Mali on hands yet and only
compile-tested it.
