drm/amdgpu: split VM mappings into smaller operations (v2)
If we can't copy entries from the GTT or fill them with one command split up the mapping operation into multiple ones.

--- Comment #1 from Nicolai Hähnle nhaehnle@gmail.com --- Hi Andy, do you have a screenshot? What version of Mesa are you using? Anything in dmesg?

--- Comment #2 from Christian König deathsimple@vodafone.de --- Crap, that looks like I haven't pushed the latest version of that to our server where Alex picket it up. There are numerous bugs in the version of the patch which went upstream.
I'm going to take a look what went wrong as soon as I have time (going to FOSDEM this weekend).

--- Comment #6 from Christian König deathsimple@vodafone.de --- Created attachment 121411 --> https://bugs.freedesktop.org/attachment.cgi?id=121411&action=edit Possible fix
Please try the attached patch if you have time.
Completely untested (not even compiled), but should do most of the trick.
Need to check in detail when I'm back home.

--- Comment #7 from Andy Furniss adf.lists@gmail.com --- Patch is good, all seems OK so far.
Testing the version of drm-next-4.6-wip that I bisected as Alex has updated and removed the fail commit from latest.
