Yes, I know, but it leaves earlier kernel versions broken, at least out of the box. > If buildroot would have a global Linux patch directory, something > like this could be added meanwhile. This clearly something that we do not want to do. See https://dev.openwrt.org/browser/trunk/target/linux/generic/patches-3.14, and you'll discover why we clearly don't want to do that. My colleague Maxime has just spent several painful days to bump the 3.14 OpenWRT stack of kernel patches to 3.16, just for the sake of being able to run OpenWRT on a 3.16 kernel. It's just ridiculous, and that's not a situation where we want Buildroot to be.
