Subject: [PATCH] KVM: propagate SHUTDOWN intercept to userspace on SVM

This patch implements forwarding of SHUTDOWN intercepts from the guest
on to userspace on AMD SVM. A SHUTDOWN event occurs when the guest produces
a triple fault (e.g. on reboot). This also fixes the bug that a guest
reboot actually causes a host reboot under some circumstances.
