This may well be a compiler bug that this commit just happens to poke. The toolchain is PowerPC hosted cross tools: x86_64-linux-gcc (GCC) 4.4.3 GNU ld (GNU Binutils) 2.20 I tried an allmodconfig build with my native compiler (gcc (Debian 4.6.2-14) 4.6.2, GNU gold (GNU Binutils for Debian 2.22) 1.11) and it worked fine. That is a large commit, so I am not sure where to go from here. --=20 Cheers, Stephen Rothwell sfr@canb.auug.org.au --Signature=_Mon__20_Feb_2012_13_39_36_+1100_V6kEvBUMPcLdO1/F Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAEBCAAGBQJPQbJoAAoJEECxmPOUX5FEaqAP/Atcpvuo7cL02arfOzSpOZay UMCFxiNRTsfYnnG5IzVpcgzpQamuwnyd87ZCBs6kF5d/ipwk1zdepgZVNQFYY9HF OUbo6xFNYo9yUGQIwpD/Hf5QA0aUBA6G5B69P7Sp1mNslkG99DXqsJ52Mn9/1iPg DcBwXOGDW5BAa1mJP/0oenoVrvebxHZbvq3kDHfZ9ylBFlS0p87OjxB6Q8Uyx00W oJuP2jqHDAjTSe24i5ybEwcPmMhIrpACaZX0PibDFcXI19R4JRape8uREkyIwfc5 gkmYwAq7zNidkgno+D3u/TDt4kczS2/DYe5jKtYFDak1/cMAMWJx4Xh5UrG502Qa ChAJnNOVv4XaZLKyyAB9jGJnuYRS/gQgyviFLeQXZzJBQXX7YHO3e9hoWbsgMJH7 /PnDcMMU3LYxjNYtcWyT6CA9nimUuED2Pxi4roi7yR955YYowh93m4OUwLNQ4Ny2 XrIc+STSZkkMuH7EEv6WAJbF/COoc0eBpOI6Ix6fvVlz/8Dp/pGhmUhJuGojPdNm R6j5dXLmmg6KTuPjnf/HnNFmhxHEoMJs2V9RMxH3aFteWDHdr9VPqoWjEvUeWhDl EISjaD0FHo3PRUVX+UiT2iGYgB9nlKWny8WXVtw2q9OQpsIBeW+vGp+gxo/DKcIu +SSVSfCYFwrTHP9aqfyw =9EL6 -----END PGP SIGNATURE----- --Signature=_Mon__20_Feb_2012_13_39_36_+1100_V6kEvBUMPcLdO1/F-- -- 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/
