So it's invalid for vunmap_pte_range() to be relying solely on update_va_mapping(). Either it should use some other method, or at least have some other method as a fallback. This is easily fixed. I guess I'll audit other uses of update_va_mapping() at the same time. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
