[PATCH 1/1] kbuild: recursive build of external kernel modules

2019-08-08 Thread Shaun Tancheff
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. Signed-off-by: Shaun Tancheff --- Makefile
