Seems like the set of HIGHMEM functions is not uniform across architectures. --=20 keith.packard@intel.com --=-5QQv7wLns3r65AR6OUOi Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iD8DBQBJAOaxQp8BWwlsTdMRAjREAJ9MdT6Bkifq1xHD1MUMEd8jjliFXQCfeD6I NqZsRqC52vWDS9BX6Q3Vgmc= =05QY -----END PGP SIGNATURE----- --=-5QQv7wLns3r65AR6OUOi-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
