    into our internal testing so we can let our test teams re-verify

Obviously I prefer b) but I'm biased on the matter and fine with whatever
you and others think is best. I just wanted to point out my concerns with
the various options.
Definitely (c).  This has already missed 5.11 (unless Paolo plans on shooting
from the hip),

No, 5.11 is more or less done as far as x86 is concerned. I'm sending the PR to Linus right now.

Paolo

which means SEV-ES will get to enjoy a full (LTS) kernel release
before these optimizations take effect.
