From: Borislav Petkov <bp@suse.de>
Issue the CPU-not-supported message only on Intel machines as this driver is Intel-only. Which means, the print statement can remain KERN_INFO for ease of debugging (no need to enable it first in dynamic debug).
While at it, correct it to say CPU "model" which is what that test does.
