Yes, you can do it this way too but I can't apply it here to play with it because gmail probably corrupted the diff: checking file Makefile Hunk #1 FAILED at 729. 1 out of 1 hunk FAILED checking file scripts/Makefile.build patch: **** malformed patch at line 98: $(DISABLE_LTO) -fverbose-asm -S -o $@ $< Please attach the diff or send it from another mail server. Thx. -- Regards/Gruss, Boris. Good mailing practices for 400: avoid top-posting and trim the reply.
