From 3fcb817840fd4bed114d6bbe7275d08310feb797 Mon Sep 17 00:00:00 2001

Subject: [PATCH] cpu: Fix cpuid check for some AMD processors.
Some venerable AMD processors do not support querying extended features
(EAX=7) with cpuid.
In this case, it is not a programmatic error and the runtime check should
simply return the isa is unsupported.
Reported-by: Davide Repetto <red@idp.it>
Reported-at: https://bugzilla.redhat.com/show_bug.cgi?id=2211747
Fixes: b366fa2f4947 ("dpif-netdev: Call cpuid for x86 isa availability.")
