I thought you wanted me to drop this one because the
dependent/relevant patches were not pushed to stable at that time. But
I re-read your email and I missed one important part that this
particular patch is valid for a separate bug introduced in IRQ stack
stuff in 4.11. I missed that important part. My apologies for that.
Again.
Greg please drop this one for both 4.4 and 4.9.
