Subject: shared features in cpuid

While reviewing changed behavior in 'xen-cpuid -d' output between Xen 4.8 and 4.9 I found commit 20e92c97f904aa460e2223c30dcad36c234496b6 ("x86/cpuid: Only recalculate the shared feature bits once").

I wonder what the mentioned "cross-vendor case" in the comment, which was removed from sanitise_featureset(), really means.

Does Xen attempt to support domU migration between AMD and Intel hardware?
