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.

Consider following example: config M def_bool y option modules choice prompt "choice list" config A tristate "a" config B tristate "b" endchoice With a defconfig like this: CONFIG_M=y CONFIG_A=y The resulting configuration would have CONFIG_A=m which was unexpected. The problem was not not all choice values were set and thus kconfig calculated a wrong value. The fix is to set all choice values when we read a defconfig files. conf_set_all_new_symbols() is refactored such that random choice values are now handled by a dedicated function. And new choice values are set by set_all_choice_values(). This was not the minimal fix, but the fix that resulted in the most readable code.

The config symbols are saved in the same order as they appear in the menu structure so it should be possible to map them to the relevant menus if desired. The implementation was tested against several minimal configs for arm which was created using brute-force. There was one regression related to default numbers which had their valid range further limited by another symbol. Sample: config FOO int "foo" default 4 config BAR int "bar" range 0 FOO If FOO is set to 3 then BAR cannot take a value higher than 3. But the current implementation will set BAR equal to 4. This is seldomly used and the final configuration is OK, and the fix was non-trivial. So it was documented in the code and left as is.

Breakage had been introduced when conf_set_all_new_symbols() got used for allmodconfig et.al. What happens is that sym_calc_value(modules_sym) done in conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES. When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER] on everything, but it has no effect on sym->curr for the symbols that already have SYMBOL_VALID - these are stuck. Solution: use sym_clear_all_valid() in there. Note that it makes reevaluation of modules_sym redundant - sym_clear_all_valid() will do that itself.
