This hasn't had a lot of time on trunk for testing but I believe it should be correct. (I was having trouble finding systems to test it on as most of the machines I have access to do not have disabled features, but it was OK on the ones I tried). Considering we have had other reports of this not working, perhaps it is best to take it. I think it should be OK on the branch, but could be a much larger impact on other devices that for example don't have SVE.

I am OK either way, taking it on the branch or being safe and letting it be tested on trunk for a release, but would probably recommend taking it if it can be rebased to the branch.
