I'm not sure why you're picking these particular patches.  VC4 has gone
through a ton of development and fixing since then, and you'd be better
served by a forklift of drm/ to 4.4 at this point than trying to pick
and choose patches.

Thanks for your feedback. Really appreciate it.

I'm not trying to forklift new feature set and fixes. I just ran into
these VC4 fixes in raspberrypi's 4.4.y tree and since these fixes
looked important enough from my vantage point and were applicable for
stable linux-4.4.y as well, I submitted them for consideration.
