xen: netback: fix printf format string warning
drivers/net/xen-netback/netback.c: In function ‘xenvif_tx_build_gops’: drivers/net/xen-netback/netback.c:1253:8: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘int’ [-Wformat=] (txreq.offset&~PAGE_MASK) + txreq.size); ^ PAGE_MASK's type can vary by arch, so a cast is needed. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> ---- v2: Cast to unsigned long, since PAGE_MASK can vary by arch. Acked-by: Wei Liu <wei.liu2@citrix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
