Thanks Paolo for the great improvements you made to the original POC patches,
I can confirm that the migration we had for Intel CPU (Haswell) is fixed with these 2 patches. I can see that for arch-capabilities, in addition to the compatibility property, you did slightly change the behavior by limiting it to AMD CPU (other x86 CPUs like Intel will have the old behavior prior 10.1 so no migration issue). Do you think it is good to make it clear in the commit log ? I'm also trying to test on an AMD CPU and will report back. Thanks, Hector
