You can `make > CONFIG_SATA_MV=y allnoconfig', you will _not_ get it set. That's always true in kconfig *anyway*. We've *never* really had an option for "do whatever you need to enable this option". We've even hard-coded this failure in our language, by introducing this horrible 'select' thing to work around it. I'd no more expect that, than I would for it to write the code for me if I type 'make CONFIG_BTRFSv2=y oldconfig'. So no, it doesn't violate the principle of least surprise. > ok, the issue is that you will only be allowed to change visible > symbols.

What was ARCH set to in your second test? If it's ARCH=x86_64 then that's expected. That's the whole point of my *other* patch to make 'ARCH=x86' be the default, so that the value of CONFIG_64BIT in your .config is *not* forcibly overridden to match the build host. That's a *separate* bug, which I also have a patch for. -- dwmw2 -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
