I can't remember the issue at the moment either, but it was a problem with some sort of config, I'll queue this up and see if anything breaks :) thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Just wondering since I didn't see it loop around in linux-next via staging #staging-next yet...

Sorry, it now just got applied, got way behind on patches :( -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This is essentially a revert of 86f69fe9c069dd8608d238581eea259caa1dfc99 ("Staging: workaround build system bug"), but to call it a revert would imply it was wrong -- rather it seems more like it is just no longer required anymore. It doesn't list the full details of the failing use case, but the most obvious would appear to be a "make allnoconfig" that subsequently had set just CONFIG_STAGING=y in the .config file, to give: paul@builder:~/git/linux-head$ grep STAGING ../staging-allno/.config CONFIG_STAGING=y # CONFIG_STAGING_MEDIA is not set # CONFIG_STAGING_BOARD is not set paul@builder:~/git/linux-head$ After building this .config (on ARM, just to be different), we see that built-in.o is created, and the final vmlinux links OK: paul@builder:~/git/linux-head$ ls -l ../staging-allno/drivers/staging/built-in.o -rw-rw-r-- 1 paul paul 257 Nov 16 18:06 ../staging-allno/drivers/staging/built-in.o paul@builder:~/git/linux-head$ file ../staging-allno/drivers/staging/built-in.o ../staging-allno/drivers/staging/built-in.o: ELF 32-bit LSB relocatable, ARM, version 1, not stripped paul@builder:~/git/linux-head$ nm ../staging-allno/drivers/staging/built-in.o nm: ../staging-allno/drivers/staging/built-in.o: no symbols paul@builder:~/git/linux-head$ ls -l ../staging-allno/vmlinux -rwxrwxr-x 1 paul paul 1236326 Nov 16 18:07 ../staging-allno/vmlinux paul@builder:~/git/linux-head$ I also tested an "allmodconfig" and did not see any problems there either. Switching back to x86-64 and testing several things there didn't show any issues either. So it appears we do not need to carry the workaround in tree any longer.
