Doh, you should. This is what you start with! :-P

Yeah, it is already on its way to every kernel near you. And looka here:
$ git grep mcmodel=large
arch/powerpc/Makefile:125: # 64bit relocation for this to work, hence -mcmodel=large.
arch/powerpc/Makefile:126: KBUILD_CFLAGS_MODULE += -mcmodel=large
arch/um/Makefile:34: KBUILD_CFLAGS += -mcmodel=large
x86 is all free of the large model now.
One less thing to worry about - gazillion more to go.
:-P
See ya on Thu.
