The big ugly one. This patch adds support for switching in and out of system management mode, respectively upon receiving KVM_REQ_SMI and upon executing a RSM instruction. Both 32- and 64-bit formats are supported for the SMM state save area. Reviewed-by: Radim Krčmář <rkrcmar@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
