kbuild: Fix compiler warning with assertion when calling 'fwrite'

2012-01-14T23:17:18Z

Reinhard Tartler discovered a corner case of calling xfwrite() where the length of the string is zero. Arnaud Lacombe suggested to use assertion for the corner case, as fwrite(3) is currently used: 1) in comment printers. Empty comment are not allowed. 2) in a callback passed to expr_print(), where the string printed is either NULL OR non-empty. 3) in the lexer, auto-generated, and unused. I feel using assertion is a good solution: 1) It cleanly takes care of the above-mentioned corner case. 2) It can be easily disabled by defining NDEBUG. 3) It asserts xfwrite() is simply a wrapper for fwrite().

Improve update-po-config output

Make the V=0 output from update-po-config be aligned correctly. Also remove an outdated comment and add a "GEN" statement. Signed-off-by: Peter Foley Signed-off-by: Michal Marek

menuconfig: let make not report error when not save configuration

2012-01-14T20:54:32Z

I find every time when I choice the 'NO' button at the dialog which let me choice whether to save the configuration before exit menuconfig, it always report the blow: " GEN /mnt/sda7/home/build/test/Makefile HOSTCC scripts/kconfig/mconf.o HOSTLD scripts/kconfig/mconf scripts/kconfig/mconf Kconfig Your configuration changes were NOT saved. make[2]: *** [menuconfig] Error 1 make[1]: *** [menuconfig] Error 2 make: *** [sub-make] Error 2 " This patch repair it.

merge_config.sh: fix bug in final check

2012-01-14T20:44:29Z

Arnaud Lacombe pointed out the final checking that the requested configs were included in the final .config was broken. The example was that if you had a fragment that disabled CONFIG_DECOMPRESS_GZIP applied to a normal defconfig, there would be no final warning that CONFIG_DECOMPRESS_GZIP was acutally set in the final .config. This bug was introduced by me in v3 of the original patch, and the following patch reverts the invalid change.

merge_config.sh: use signal names compatible with dash and bash

2012-01-14T20:44:29Z

The SIGHUP SIGINT and SIGTERM names caused failures when running merge_config.sh with the dash shell. Dropping the "SIG" component makes the script work in both bash and dash. Signed-off-by: Darren Hart Acked-by: John Stultz Cc: Michal Marek Signed-off-by: Andrew Morton Signed-off-by: Michal Marek

kconfig: add merge_config.sh script

2012-01-14T20:44:28Z

After noticing almost every distro has their own method of managing config fragments, I went looking at some best practices, and wanted to try to consolidate some of the different approaches so this fairly simple infrastructure can be shared (and new distros/build systems don't have to implement yet another config fragment merge script). This script is most influenced by the Windriver tools used in the Yocto Project, reusing some portions found there. This script merges multiple config fragments, warning on any overridden values. It then sets any unspecified values to their default, then finally checks to make sure no specified value was dropped due to unsatisfied dependencies. I'm sure this implementation won't work for everyone, and I expect it will need to evolve to adapt for various use cases. But I think its a reasonable starting point.

kconfig/streamline-config.pl: Fix parsing Makefile with variables

2012-01-13T23:01:48Z

Thomas Lange reported that when he did a 'make localmodconfig', his config was missing the brcmsmac driver, even though he had the module loaded. Looking into this, I found the file: drivers/net/wireless/brcm80211/brcmsmac/Makefile had the following in the Makefile: MODULEPFX := brcmsmac obj-$(CONFIG_BRCMSMAC) += $(MODULEPFX).o The way streamline-config.pl works, is parsing all the obj-$(CONFIG_FOO) += foo.o lines to find that CONFIG_FOO belongs to the module foo.ko. But in this case, the brcmsmac.o was not used, but a variable in its place. By changing streamline-config.pl to remember defined variables in Makefiles and substituting them when they are used in the obj-X lines, allows Thomas (and others) to have their brcmsmac module stay configured when it is loaded and running "make localmodconfig".
