Please pull from:

	git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild.git

All patches except a bunch of documentation fixes has been in -mm at least
a couple of -mm's with no or little feedback.
The headlines:

o Added unifdef to the kernel tree to provide better support for headers_*
o Build fails if there are undefined symbols in a module
o Run modpost on vmlinux also in case of non-module build

Patches will be sent to lkml as follow-up to this mail.
