Hi Chris,

I see the warning even with below batch,

[Intel-gfx] [PATCH 50/70] drm/i915: The argument for postfix is redundant
http://patchwork.freedesktop.org/patch/46601/

the following patch need to be updated as it uses olr,
[Intel-gfx] [PATCH 51/70] drm/i915: Record the position of the start of 
the request
http://patchwork.freedesktop.org/patch/46612/

Do we need some of the previous patches in series as well?

This patch is fixing the issue in the current code, do you think we can 
get this in its current state?

regards
Arun
