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.
