When a different output directory is specified during the build process (with O= or KBUILD_OUTPUT), the call to adjust_autoksyms.sh script fails with the following error: /bin/sh scripts/adjust_autoksyms.sh \ "make KBUILD_MODULES=1 -f ../Makefile autoksyms_recursive" /bin/sh: scripts/adjust_autoksyms.sh: No such file or directory make[2]: *** [vmlinux] Error 127 make[1]: *** [sub-make] Error 2 make: *** [__sub-make] Error 2 Using the absolute path with $(srctree) variable solves the problem. This is in case the CONFIG_TRIM_UNUSED_KSYMS option is specified.

I suspect it's the proper way to fix the issue but I may miss some of the details of the top kernel Makefile. It does work for my separated output directory setup and I verified it still compiles an in-sources setup as well (even if it's obvious...).
