KVM: SVM: Implement workaround for Erratum 383
This patch implements a workaround for AMD erratum 383 into
KVM. Without this erratum fix it is possible for a guest to
kill the host machine. This patch implements the suggested
workaround for hypervisors which will be published by the
next revision guide update.
[jan: fix overflow warning on i386]
[xiao: fix unused variable warning]
