So we'd really need Linux to clean this up before we use -Wpointer-arith, or we have to do extra porting effort to keep files in sync. I suppose I don't mind vaddr_t being defined and people using it if they want to. At least it is probably clearer that translation to/from char* or long to do pointer arithmetic. However, I'm less sure about a wholesale conversion of Xen away from use of 'unsigned long'. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
