I'm focusing on x86 at the moment because x86 is the only architecture that's *broken* in this respect. The other architectures that you mention below, where they support 64-bit kernels, all work fine with only *one* ARCH= setting covering all configurations. It's only x86 where we haven't actually *finished* the merge. > I am working with configuration for mips, sh, powerpc, arm and x86. > Some of them are for real board, some of them are to regress-test > compilers, binutils and kernel builds.

FWIW I usually solve this problem with a two-line GNUmakefile: ARCH := arm include Makefile I haven't checked whether it works for out-of-source-tree builds; I bet it could be made to. I would love to see $ARCH turned into a proper configuration option. -- 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
