Replace the config_is_*() macros with a variant that allows for grepping for usage of CONFIG_* options in the code. Usage: if (IS_ENABLED(CONFIG_NUMA)) or #if IS_ENABLED(CONFIG_NUMA) The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y' or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if the option is 'm'. Only boolean and tristate options are supported. Reviewed-by: Arnaud Lacombe <lacombar@gmail.com> Acked-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Michal Marek <mmarek@suse.cz>
