Applying these patches on top of my drm-etnaviv-devel branch:

staging: etnaviv: debugfs: add possibility to dump kernel buffer
staging: etnaviv: change etnaviv_buffer_init() to return prefetch
staging: etnaviv: remove submit type
staging: etnaviv: rewrite submit interface to use copy from user

with the corresponding DDX changes results in a kernel which silently
locks solid when Xorg starts up.
