Sorry for that. This is for "not to re-compile the whole tree once a tiny header file has changes" right?

just tried to compile this ontop of the tip tree and it ended with: |kernel/irq/irqdesc.c:12:26: fatal error: linux/export.h: No such file or directory
I guess your tree provides that file.

macros, I see. THIS_MODULE is quite simple. What about moving this part from module.h which is hidden behind ifdef MODULE and make it avaiable as a separate headerfile with no children?
