[Xen-devel] [PATCH v2] xen: netback: fix printf format string warning

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

drivers/net/xen-netback/netback.c: In function âxenvif_tx_build_gopsâ:
drivers/net/xen-netback/netback.c:1253:8: warning: format â%luâ expects 
argument of type âlong unsigned intâ, but argument 5 has type âintâ [-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@xxxxxxxxxx>
----
v2: Cast to unsigned long, since PAGE_MASK can vary by arch.
