I think the hypervisor bit should be given a better name than 'raz' -- although it is read-as-zero on real hardware that doesn't distinguish it from other raz bits, or describe what it does. 'hypervisor' maybe, to match 'X86_FEATURE_HYPERVISOR' elsewhere in the Xen code? With that change, Acked-by: Tim Deegan <tim@xxxxxxx> Cheers, Tim. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
