[PATCH 08/23] drm/via: use drm_mm instead of drm_sman

[James Simmons]

> Chris Wilson rightly complained that this doesn't explain the list_del
> magic going on. New commit msg reads:
> 
>     To make the transition in a piece-wise and bisectable way possible,
>     I've hijacked the ->owner_list from drm_sman. While transitioning, the
>     list_add was done by the driver, while the list_del was still done by
>     the dying sman code.
>     
>     Now that we are in full control of ->owner_list, do the list_del
>     ourselves.
> 
> He also noted the superflous additions of INIT_LIST_HEAD and the stale
> comment about spinlock locking in the idr allocation (protected by
> dev->struct_mutex) that I've copied over. All fixed up and pushed out for
> the moment to my fdo repo:
> 
> http://cgit.freedesktop.org/~danvet/drm/log/?h=kill-with-fire
