Subject: [PATCH] SVM: reliably detect if SVM was disabled by BIOS


From: Joerg Roedel <joerg.roedel@....com>

This patch adds an implementation to the svm is_disabled function to
detect reliably if the BIOS disabled the SVM feature in the CPU. This
fixes the issues with kernel panics when loading the kvm-amd module on
machines where SVM is available but disabled.
