The filename of the patch is: x86-mm-give-each-mm-tlb-flush-generation-a-unique-id.patch and it can be found in the queue-4.9 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

commit f39681ed0f48498b80455095376f11535feea332 upstream.
This adds two new variables to mmu_context_t: ctx_id and tlb_gen. ctx_id uniquely identifies the mm_struct and will never be reused. For a given mm_struct (and hence ctx_id), tlb_gen is a monotonic
Greg, I've only pulled the unique ctx_id part of the original patch and not the tlb_gen changes. The unique ctx_id is a very simple change without needing other related changes that tlb_gen will require.
You may want to update the comment to reflect this.
I try to keep the commit text identical, but am willing to add a note at the top or usually, the bottom of the text to show what changed in the specific stable patch. Can you give me some text that I can put there to reflect what you changed here?
thanks,
