So it seems we are using 'subdir-m' but that is now gone? Is there a recommend pattern for backward compatibility?

Please convert subdir-m += dir1 subdir-m += dir2 into obj-m += dir1/ obj-m += dir2/ Thanks.

When building a tree of external modules stage 2 fails silently as the root modules.order is empty. Modify the modules.order location to be fixed to the root when KBUILD_EXTMOD is specified and write all module paths to the single modules.order file.
