Its singular here.. but in the example its plurar.

Hm, physical address is zero, and the size is 0xbignumber? Or is the '0' denotating a seperator of arguments, so it is 0xb000.. for physical address and 0x20000 for size? > + interrupts = <1 15 0xf08>; > +}; > -- > 1.7.2.5 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
