From: Alex Deucher alexander.deucher@amd.com
[ Upstream commit a6dea2d64ff92851e68cd4e20a35f6534286e016 ]
We are dropping the IOMMUv2 path, so no need to enable this. It's often buggy on consumer platforms anyway.
This is not needed for stable.
I agree. I was about to comment in the 5.10 patch as well.
Regards, Felix
Alex
