Anything +other than minor changes should be built, booted and tested with +comprehensive (and heavyweight) kernel debugging options enabled. + +These debugging options can be found in kernel/configs/x86_debug.config +and can be added to an existing kernel config by running: + + make x86_debug.config + +Some of these options are x86-specific and can be left out when testing +on other architectures.
