KVM: CPUID: add support for supervisor states
Current CPUID 0xd enumeration code does not support supervisor states, because KVM only supports setting IA32_XSS to zero. Change it instead to use a new variable supported_xss, to be set from the hardware_setup callback which is in charge of CPU capabilities. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
