I sent Jason a couple of mails last time when he posted (and before that the previous maintainer when he tried to merge it). All were fairly "beratungsresistent". If you're truly interested i can dig out the mails or do a fresh review. Long ago I did a quite clean x86-64 kgdb for Linux 2.4 based on the old 2.4 stub that dropped in without any strange other hooks (except for a straight forward change to the serial code). It worked just fine this way. -Andi -- 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/
