Would it be possible to apply

to stable kernels?

I'm finding it quite easy to crash my Thinkpad X1 Carbon 6th gen with Blender on Fedora 34 (which is using the 5.11.y kernels). It applies cleanly, and I've been running 5.11.16 with the patch applied and seeing no obvious ill effects.

As 5.11.y is now end-of-life, and has been for a week or so, what kernel(s) would you want this applied to given that 5.12.y is the latest stable kernel tree?

What prevents you from moving to 5.12.y now?
