ERROR: "phys_to_mach" [drivers/net/xen-netfront.ko] undefined! ERROR: "phys_to_mach" [drivers/net/xen-netback/xen-netback.ko] undefined! ERROR: "phys_to_mach" [drivers/block/xen-blkfront.ko] undefined! The mfn_to_pfn and pfn_to_mfn functions get inlined in these modules and those functions require phys_to_mach. Export the symbol to fix the link errors.
