Commit c50bfd08 does not pick cleanly in the Vivid(3.19) kernel. The 3.19 kernel does not have intel_fbdev_blank() or intel_fbdev_pan_display(). intel_fbdev_blank() was added by commit 03e515f7 in v4.1-rc1. intel_fbdev_pan_display() was added by commit d9a946b5 in v4.2-rc1.
Can you confirm where or not commit c50bfd08 is needed in the 3.19 Wily kernel? If it is, I can backport the commit.

Generally, an SMEP/SMAP violation should cause the involved process killed, an oops from page fault exception generated to the syslog, and the system survived.
