Not sure exactly what Arnd is trying to do, but the same file should not be touched from multiple points in case Kbuild descends into mach-omap2/ and memory/ at the same time. I recommend to put copies in each directory: arch/arm/mach-omap2/emif-asm-offsets.h drivers/memory/ti-emif-asm-offsets.h If you want me to send a patch, I will give it a try. -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
