[PATCH 0/8] DRM File Context Cleanups

[David Herrmann]

Hi

Some rather random cleanups on drm_file and whatever I found on the way. The
idea here really is to get to a point where we can allocate drm_file from a
kernel context to get in-kernel rendering to work. This would allow allocating
dumb-buffers, dma-bufs, etc. from within the kernel and get fbdev generically
working, as well as panic renderers et al.

The only critical thing is drm_file->filp, which points to the underlying
"struct file". We really don't want to fake a "struct file" for in-kernel
renderers (even though it is possible), so this series tries to get rid of all
non-legacy users of it. The only real place left is vm_mmap() in drm_bufs.c.

Tested on i915 only.

Thanks
David
