From e223da96bf16bee7f6c4c3aed1ade44a48aff0d3 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Mon, 16 Nov 2015 19:58:49 -0500 Subject: [PATCH] staging: drop kbuild workaround dummy module from top dir 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.
