Here's a combined patch that compiled fine for me on
Linux/x86-64. Jeff, could you test it under Xen, please?

I've finally got functional access to a box which exhibits the problem; so yes, I'll take this patch for a spin and report back.

This patch doesn't work. It causes infinite mutual recursion between init_cpu_features and get_cpu_features.

AFAICT, you can't use the CPUID_XXX macros (which call get_cpu_features) until init_cpu_features is complete.
