From 99f925ce927e4ac313d9af8bd1bf55796e2cdcb1 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 23 Nov 2015 11:12:21 +0100 Subject: x86/cpu: Unify CPU family, model, stepping calculation Add generic functions which calc family, model and stepping from the CPUID_1.EAX leaf and stick them into the library we have. Rename those which do call CPUID with the prefix "x86_cpuid" as suggested by Paolo Bonzini. No functionality change.
