First half of kernel log

Description of problem:
Kernel panics and crashes with "kernel BUG at security/selinux/hooks.c:4511

Version-Release number of selected component (if applicable):
3.16.0-0.rc7.git1.1.fc22

How reproducible:
I can get it to crash at will

Steps to Reproduce:
1. download and build waffle with DRM support
2. download and build piglit
3. run piglit run -p drm quick.py
4. Crash

It also sometimes crashes just by X starting up.  Sometimes, I can't even get a log-in screen.

Actual results:
crash

Expected results:
piglit may report errors, but it shouldn't kernel panic

Additional info:
see attached pictures

It's worth noting that running piglit bangs on drm fairly hard as it is a GL test suite.  However, as I said, I've had it crash under less stress than piglit.
