Description

When originally implementing support for newer xsave usage in the kernel in 8539, we had to deal with some set of AMD processors which needed manual exception handling. With the advent of AMD EPYC processors we have several that now no longer need this handling and therefore we should update the check to make sure it doesn't fire on them.
