And people wonder why I wanted to give Fengguang a round of applauds there. I guess I was one of the first people to get his testing, as it found a lot of little things for me that my own tests missed. > > I have most of the prebuilt toolchains[2], and two line wrappers to set > the ARCH/CROSS_COMPILE, but as it stands, it seems I really don't > need those any more.

Feel free to modify that config. But really, there should be no more excuses for kernel developers not doing cross compiles of most archs. It's really that simple. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
