[PATCH v4 00/17] drm: add gem ttm helpers, rework mmap workflow.

Not just ttm/not-ttm.  gem_driver->fops->mmap is the only fops callback
where we can't use a generic gem callback today.  This series tries to
fix that with the new drm_gem_object_funcs->mmap hook, so the mmap()
code path isn't the odd one which works different than every other
drm_gem_object operation.

Which details?

cheers,
