From ce97e13e52848c6388598696b7d44748598db759 Mon Sep 17 00:00:00 2001 From: Al Viro <viro@ZenIV.linux.org.uk> Date: Sun, 26 Oct 2008 05:12:34 +0000 Subject: [PATCH] fix allmodconfig breakage If you use KCONFIG_ALLCONFIG (even with empty file) you get broken allmodconfig/allyesconfig; CONFIG_MODULES gets turned off, with obvious massive fallout. 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.
