What I do during the merge of a new kernel, before -rc1 is released is to 
manually edit the Makefile to increment the kernel version and make the 
EXTRA_VERSION be -rc0. That way the conditional statements work with mainline.

I have enough trouble keeping up with mainline, thus I leave -next alone.
