btw., block.git would be one of my first guesses - Jens Cc:-ed.

normally there's an easy way to find out the source commit of build 
failures. Try something like:

 git-bisect reset
 git-bisect start
 git-bisect good v2.6.26-rc8
 git-bisect bad linux-next/master
 git-bisect run make kernel/fork.o

... this should lead you to the commit that broke the build 
automatically. (as long as everyone keeps make oldconfig compatibility)
