kbuild.git contains at the moment 36 patches which is all for the upcoming merge window.
It has been rebased to latest -linus git tree.
See shortlog below.

Pending patches
- Section garbage collection (Denys Vlasenko)
  I had too little time to play with it so it will not hit this merge window :-(
- Improved stripping (Jan Beulich)
  needs review
- Enhance make rpm (Florin Andrei)
  needs review
- merge uboot mkimage (Josh Boyer)
  await an update with a renamed script, maybe I already got it

- Access enviromnet variables (Roman Zippel)
  seems I have lost the original patch - needs to serach
- arch/Kconfig (Mathieu)
  (Maybe Andrew have them, needs follow up)
- xconfig search dialog (Shlomi Fish)
  needs review + test

Known issues
- make rpm are reported buggy
  I have plenty of mails with bug reports but no patches and I do not know rpm myself
- zillion of mails from Robert P. J. Day

- Segmentation violation when seeing recursive symbols
  I added the bug but have not had time to fix it yet 

TODO items (from my mailbox - I have plenty more)
- asm-offset useable from modules (Oleg had a half backed solution)
- modpost should use err(), warn() etc (suggestyed by Rusty)
- less kernel hardcoding in kconfig (Rob Landley)
- emit dependencies from "depends" (Bernhard Fischer)
- fix select (whatever that means)
- allow kconfig to accept overrides (Jan Engelhart)
  maybe there is a patch, needs followup
- document kernel build better (Andreas Hermann)
  just a start, more is needed
  requires major surgery to do correct - we use CC too early
- i18n patch for mconf and friends (from Kernel Translator project)
  is old but several bits of it needs to be applied to better support i18n
- i18n support in kernel
  some like it, others don't. But now we have japanese versions of some docs...
- use GCC --combine (David Woodhouse)
- more color themes (Jan Engelhart)
  and I would like them selectable from inside menuconfig
- walk throug the ~15 qconf related patched - are they relevant?
- document use of __init and related sections
- Use seperate sections for all init sections to improve checking
- improve headers_check (10x speed up is possible by doing a dir-by-dir check)

On top of this I have my personal todo items such as:
- document kconfig a bit
- make it possible to include all kconfig files
- clean up kconfig files
- documet use of HAVE_ in kconfig files
- modern ncurses interface for menuconfig (ala tig, htop and others)
- etc...

So all in all no reasons to be bored.
Did you send me a patch that is neither listed above nor below then please resend.
Any help with the above are much appreciated!

Note: The kbuild stuff is done only in my spare time and
      with 3 kids, a wife and a full-time job I am often lacking behind.

A summary of what is planned to be submitted in next merge window for kbuild.
The shortlog below have additional details but the headlines are:

o Make the kernel buildable on a cygwin box (but not without a few glitches)
o detect unterminated device id list
o add export_report as a valid top-level make target
o add script to find unused kconfig symbols (try it!)
o allow a user to specify additional flags on the commandline with
  CFLAGS, AFLAGS or CPPFLAGS. The flags will be appended to the kernel defiend flags

The CFLAGS change will conflict with Andi's x86 patches and I fix it
before pushing if Andi's patches are pushed first.
Otherwise no conflicts.

The changes that I have sent to a number of arch maintainers
lately are not included.
I expect them to be applied by the respective arch maintainers.

The --gc-section cleanup from Denys Vlasenko will be included in
kbuild after the merge window so we can try it out in -mm before
hitting mainline.

Jan Beulich kconfig patch will most likely be included.
Need to test it first.

Marej menuconfig improvement may also be included.
Last patch looked good but have not made up my mind if it
really help people.

Patched referred below are available at at kbuild.git
in an hour or so.

Short intro to content of kbuild.git at the moment.

Everything are targeted for next merge window.

section mismatch
      kbuild: make better section mismatch reports on i386, arm and mips
      kbuild: The .paravirtprobe section is obsolete, so modpost doesn't need to handle it
      kbuild: ignore section mismatch warnings originating from .note section
      kbuild: refactor code in modpost to improve maintainability
      kbuild: warn about references from .init.text to .exit.text
      kbuild: remove hardcoded apic_es7000 from modpost
      kbuild: refactor code in modpost
      kbuild: remove hardcoded _logo names from modpost
      kbuild: suppress modpost warnings for references from the .toc section as used by powerpc
      kbuild: whitelist references from variables named _timer to .init.text

Several changes to either improve reporting - or to ignore false positives.
In particular modpost now check for and warn about references from .init.text to .exit.text
This check caugth several real bugs - which for the most part are already fixed in upstream.
modpost now does a better job finding the symbols using addend - this works for me
but had caused troubles in the past. If modpost suddenly bails out with a segmentation
violation this may the the culprint.
In addition some trivial code refactoring was done to improve maintainability of modpost.

      kconfig: use POSIX equality test in

      scripts: Make cleanfile/cleanpatch warn about long lines
Improved so we all adhere to 80 lines (in)sanity

      kbuild: avoid environment to set variables used by kbuild
I had a report that a user tried to do:
EXTRA_CFLAGS=FOO make fs/nfs/
This is not supposed to impact the build so make sure it does not.

      kbuild: add support for reading stdin with gen_init_cpio
      kbuild: add support for squashing uid/gid in
initramfs improvements

      kbuild: asm-offsets.h is now cleaned with O=.. builds

      kbuild: document cc-fullversion
      kbuild: New 'cc-fullversion' macro
      powerpc: Refuse to build 64-bit with GCC-4.2.0 and CONFIG_MODULES
Add and use cc-fullversion to obtain exact gcc version
See documentation in Documentation/kbuild/makefiles.txt

What's next?
-> davem has requested to add a new section used for code modifying support.
   The actual section name to use needs to be sorted out.
-> A few cygwin specific changes may hit kbuild - to allow the kernel to be built
   using cygwin on a windoze box.
-> A few trivial kconfig changes are pending. Needs to review them before they are ready.
-> A speed-up of headers_check is in the works. Got stalled but will look into it soon.
   The check goes down to ~3 sec on my not-so-fast machine
-> If I get really bored I may start a 'cleaning up all files' round.
   If someone would help out here it would be appreciated.
   These change will then be merged via the arch-maintaines and not really kbuild stuff..
