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      kbuild: The .paravirtprobe section is obsolete, so modpost doesn't need 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 
but had caused troubles in the past. If modpost suddenly bails out with a 
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 
   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' 
   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..
