From d4330ef2fb2236a1e3a176f0f68360f4c0a8661b Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Thu, 22 Apr 2010 12:33:11 +0200 Subject: KVM: x86: Add callback to let modules decide over some supported cpuid bits This patch adds the get_supported_cpuid callback to kvm_x86_ops. It will be used in do_cpuid_ent to delegate the decission about some supported cpuid bits to the architecture modules.
