dmesg: boot up with call trace and error on IVB (Apple Macbook Pro)
Environment:
--------------------------
Kernel: (drm-intel-next-queued)815ca9817afc1c1a45799fb9d4a4f413b7b1517c

drm/i915: inline vma_create into lookup_or_create_vma
Description:
--------------------------
Test with latest -next-queued kernel, there's "call trace" and error messages
in dmesg after machine booting up. I have tried other IVB platforms, there's no
such issue. I can't find a good commit by checking some older kernels.
Reproduce step:
--------------------------
1. change kernel and reboot
2. check the dmesg</pre>
