From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Rothwell Subject: linux-next: build failure after merge of the tty tree Date: Tue, 30 Sep 2014 17:39:00 +1000 Message-ID: <20140930173900.51839e76@canb.auug.org.au> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha256; boundary="Sig_/SgY1gAK9ldqL5_SSxtpdnE4"; protocol="application/pgp-signature" Return-path: Received: from ozlabs.org ([103.22.144.67]:51785 "EHLO ozlabs.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750988AbaI3HjN (ORCPT ); Tue, 30 Sep 2014 03:39:13 -0400 Sender: linux-next-owner@vger.kernel.org List-ID: To: Greg KH Cc: linux-next@vger.kernel.org, linux-kernel@vger.kernel.org, Sebastian Andrzej Siewior --Sig_/SgY1gAK9ldqL5_SSxtpdnE4 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hi Greg, After merging the tty tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: drivers/built-in.o: In function `.serial8250_stop_tx': 8250_core.c:(.text+0xda1f4): undefined reference to `.__xchg_called_with_ba= d_pointer' drivers/built-in.o: In function `.serial8250_tx_chars': (.text+0xda42c): undefined reference to `.__xchg_called_with_bad_pointer' drivers/built-in.o: In function `.serial8250_start_tx': 8250_core.c:(.text+0xda630): undefined reference to `.__xchg_called_with_ba= d_pointer' Caused by commit d74d5d1b7288 ("tty: serial: 8250_core: add run time pm"). xchg is called with &p->rpm_tx_active and that is an unsigned char. PowerPC (at least) only allows xchg with objects 4 (or 8 on 64 bit) bytes long. I have used the version of the tty tree from next-20140926 for today. --=20 Cheers, Stephen Rothwell sfr@canb.auug.org.au --Sig_/SgY1gAK9ldqL5_SSxtpdnE4 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJUKl4eAAoJEMDTa8Ir7ZwVTUwP/R6EUqxJt4M0t9I1Ldjl0gAx FLoqJpXkoSqCVfTD/omKt/DylA+kSx7LWU1MqkpXfwt60ne2ZZgNrkik5yrrTS3Y wFGc/+UIXGD6LyMeJz9v7euwmuJQ15eLhySPOCYCjciS2IVVBaA3jREleykDQmTy kGXWo9LZPwaC+em4y5tPIy7VHWl+KJiIVLlrS5UhNC92YDMVFeCx3dgGkQ/MgQed agkz0YPYNAUJCR9aagV7US6Z6Y5Tje0q63vmy+5jtqxfMDIVIraEcHhCwh/Kgc7m Sc7KxrOE0DA/EkaCV12DZoY1NOoCDWr2uWkoT7zeQw/Cv0w29tkUX5WLqXHWo2S+ c5RCUaPKecWQgXrYLkuv14sfk9KGRwDHlvgmbEtQFxLn5Z4GNZvDSIM227EJ29f/ /hteSEQuQgNm9o78r9OA1IgBYcyKAxruJggFVdMkdrKVUvy+lw1gxBa+MR8/zvYZ LelKifAmFXWMqc0DEc0F2bXGgkHPV5gw93ZNv5tV2y54qePwxQBAuqZmn6YDySbC mGgP7TiMpU1QNTmzVHc2EgtMMC7tycWdXa7PA5VvIa55Um0fJHlaPM1a85tvz3vN 4Vuuraof1T6tH/YADFAwZHJtzZu1U0mTC1cGdsEF5nx9Z+yyB47/eKBddCUEmATZ ikiVcMtGijQQ5M3kPxAz =fAjG -----END PGP SIGNATURE----- --Sig_/SgY1gAK9ldqL5_SSxtpdnE4--
