arm/xen: Export phys_to_mach to fix Xen module link errorstracking-ll-misc-fixes-ll-20131206.0tracking-ll-misc-fixes-ll-20131205.0tracking-ll-misc-fixes-ll-20131204.0
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.
