I'm not sure that I understand your argument. If you are compiling for the simulator, and you have CONFIG_KEXEC enabled, then the build will fail. I think that is a problem. Instead of my patch, should CONFIG_KEXEC depend on CONFIG_IOSAPIC? -- Horms H: http://www.vergenet.net/~horms/ W: http://www.valinux.co.jp/en/ _______________________________________________ fastboot mailing list [email protected] https://lists.osdl.org/mailman/listinfo/fastboot
