From: Steven Rostedt If CONFIG_IKCONFIG is set but CONFIG_IKCONFIG_PROC is not, then gcc will optimize the config.gz out, because nobody uses it. This patch adds "__used" to the config.gz data to keep it around so that code like extract-ikconfig can still find it. [ Impact: allow extract-ikconfig to find config.gz ] Signed-off-by: Steven Rostedt --- kernel/Makefile | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/kernel/Makefile b/kernel/Makefile index 2093a69..d0c84e6 100644 --- a/kernel/Makefile +++ b/kernel/Makefile @@ -119,7 +119,7 @@ $(obj)/config_data.gz: .config FORCE $(call if_changed,gzip) quiet_cmd_ikconfiggz = IKCFG $@ - cmd_ikconfiggz = (echo "static const char kernel_config_data[] = MAGIC_START"; cat $< | scripts/bin2c; echo "MAGIC_END;") > $@ + cmd_ikconfiggz = (echo "static const char kernel_config_data[] __used = MAGIC_START"; cat $< | scripts/bin2c; echo "MAGIC_END;") > $@ targets += config_data.h $(obj)/config_data.h: $(obj)/config_data.gz FORCE $(call if_changed,ikconfiggz) -- 1.6.3.3 -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
