Why does it matter? People using the API get appropriate constants to use, and it still functions the same. > Could you address why we can't use the existing placement > of these bits? The existing placement has holes in the array, and Xen-specific synthetic leaves, both of which are inappropriate in a new API/ABI. The ABI is now formed of Intel-specified and AMD-specified leaves only, with the Xen synthetic leaves on the end, and no holes. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
