74670c7bb9 gem_stress: ducttaping mandatory 
In other news: We've been missing a unmapping_mapping_range somewhere
in the kernel. But lazy me never came around to digging up the real
cause.

4227da8c3c gem_stress: Add an option to test handling of signals 
As signals cause the syscalls to be interrupted, we often need to clean
up partial state before returning to userspace. Often a source of
unamusing bugs, so encourage gem_stress to provoke them.

3ddc799fbf testdisplay: fix possible_crtcs check so LVDS works 
When using testdisplay on GM965 and Pineview with LVDS, it will fail to
set a mode because the first unused crtc can't be used for LVDS.  So
check the possible_crtcs to make sure the crtc can be used.
