Subject: [PATCH] KVM: x86: Inter-privilege level ret emulation is not
 implemeneted

commit 9e8919ae793f4edfaa29694a70f71a515ae9942a upstream.

Return unhandlable error on inter-privilege level ret instruction.  This is
since the current emulation does not check the privilege level correctly when
loading the CS, and does not pop RSP/SS as needed.
