Only enabled if XEN_DEBUG is enabled. We print a warning when: pfn_to_mfn(pfn) == pfn, but no VM_IO (_PAGE_IOMAP) flag set (and pfn is an identity mapped pfn) pfn_to_mfn(pfn) != pfn, and VM_IO flag is set. (ditto, pfn is an identity mapped pfn) [v2: Make it dependent on CONFIG_XEN_DEBUG instead of ..DEBUG_FS] [v3: Fix compiler warning] Reviewed-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
