From 37ea0fcb6a3f3318bf45888e624722a2945cec04 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Wed, 17 Oct 2012 09:39:10 +0100 Subject: xen: sysfs: fix build warning. Define PRI macros for xen_ulong_t and xen_pfn_t and use to fix: drivers/xen/sys-hypervisor.c:288:4: warning: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'xen_ulong_t' [-Wformat] Ideally this would use PRIx64 on ARM but these (or equivalent) don't seem to be available in the kernel.
