    unbreak allmodconfig KCONFIG_ALLCONFIG=... · 6b87b70c

    	Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used
    to be equivalent to make allmodconfig; these days it hardwires MODULES to n.
    In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is
    treated as if it set it to n.
    
    	Regression had been introduced by commit cfa98f ("kconfig: do not
    override symbols already set"); what happens is that conf_read_simple()
    does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and
    has conf_set_all_new_symbols() skip modules_sym.
    
    	It's pretty easy to fix - simply move that call of sym_calc_value()
    into the callers, except for the ones in KCONFIG_ALLCONFIG handling.
