Hardware 3D acceleration doesn't work anymore with the latest git kernel

[Christian Zigotzky <chzigotzky@xenosoft.de>]

Alex,

Thanks for your fast reply. I have looked in the first bad commit 
e60e1ee60630cafef5e430c2ae364877e061d980 (Merge tag 'drm-for-v4.15') [1].
I have found a lot of kzalloc changes. I am sorry, I don't have any 
experiences with this code. I only know that my Radeon HD6870 doesn't 
have hardware 3D acceleration anymore.

Maybe I could revert the drm_gem_object_init and ttm_bo_init changes but 
the kzalloc changes are too much. I think I need help to solve this issue.

Thanks,
Christian
