Description:
------------------------
After started X and played the video with command "mplayer -vo xv MPEG-2.mpeg",
the monitor failed to play the video and only showed a black window in the
middle. I took a picture and added it in the attachment. 
And the console will printed the error info like: "X11 error: BadAlloc
(insufficient resources for operation)".
The dmesg info and the Xorg.log are attached. You can check it in the
attachment.

This is a kernel regression. I finished the bisect and it shows:
7e0d96bc03c140cb8183955ad6f0290caa731e64 is the first bad commit

    drm/i915: Use multiple VMs -- the point of no return

    As with processes which run on the CPU, the goal of multiple VMs is to
    provide process isolation. Specific to GEN, there is also the ability to
    map more objects per process (2GB each instead of 2Gb-2k total).

    For the most part, all the pipes have been laid, and all we need to do
    is remove asserts and actually start changing address spaces with the
    context switch. Since prior to this we've converted the setting of the
    page tables to a streamed version, this is quite easy.

    One important thing to point out (since it'd been hotly contested) is
    that with this patch, every context created will have it's own address
    space (provided the HW can do it).

    v2: Disable BDW on rebase

    NOTE: I tried to make this commit as small as possible. I needed one
    place where I could "turn everything on" and that is here. It could be
    split into finer commits, but I didn't really see much point.
