> I see the problem now. However, so far, no other architecture has been doing this. 'grep -e -include arch/*/Makefile' shows only one instance in arch/arm, but that include is a static file with no dependencies. Is it really necessary to include asm/current.h when compiling _every_ file? Sure, you get it via many common headers, but then you don't need to add it explicitly :). But if Arnd thinks this is OK, I will merge a patch that serializes scripts/mod/empty.o and asm-generic.

According to my architecture maintainer it is mandatory.
