[GIT PATCHES] kbuild updates

[Sam Ravnborg <sam@ravnborg.org>]

Hi Linus.

kbuild updates as accumulated over the last few months.
All patches has been in -mm in one or several versions.

Most noteworthy:
1) -Wundef added to CFLAGS. This is the cause of several new warnings,
   which for the most part has been fixed for now.
2) "PREEMPT" in UTS_VERSION. So we complain when dealing
   with modules compiled for a wrong kernel
3) Introduced Kbuild.include (the cause of most of
   the changes lines in top-level Makefile).
   It killed a lot of duplicate code
4) Introduce debug_kallsyms to better debug situations where
   kallsyms fails the consistency check
5) Added support for building rpm tarballs of source

Some of this was leftovers from my old bitkeeper tree, and authorship
is not correct due to wron cogito usage. The changelog message though 
attributes the correct author.
