I experienced a few crashes with similarly looking backtraces with lots of FF
and KDE5 Okular et al. windows open. Applied this patch to kernel 4.9.6 and
since then haven't had any issues. Although I had no reliable way how reproduce
the crash to 100% confirm patch's effectiveness, at least the patch seems to
not cause any bad side effects.

Tested on ~AMD64 Gentoo with G98M [Quadro NVS 160M]
