arm/xen: Export phys_to_mach to fix Xen module link errors
Various xen drivers fail to link when built as modules with the following error: ERROR: "phys_to_mach" [drivers/xen/xen-gntalloc.ko] undefined! 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. Signed-off-by: Josh Boyer <jwboyer@fedoraproject.org> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
