Yes, this is what I meant above by "seed"ing the configurations, and it is something I do all the time with my autobuilder here for things like allnoconfig where I want to ensure that certain options have specific values. When I talked to Olof about it, he seemed to be against using the facility in his autobuilder. I'm not clear on why that was, but I suspect it's because Olof wants to test real allnoconfig builds. An alternative is we could have a HAVE_GCC_PR58854_FIX preprocessor conditional, and pass in KCFLAGS=-DHAVE_GCC_PR58854_FIX to the kernel to bypass the check. Either way, I think we need Olof's input on this to say what he's willing to do. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net.
