Do some fields after the cpumask need to line up in both structures? Placing a dummy cpumask in the shadow_page structure might make most sense. For the other one I'll have to think a bit. The need for GDT entries per CPU currently obviously means scaling much past a few hundred CPUs is going to be difficult. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
