[GIT PATCH] kbuild fixes

[Sam Ravnborg <sam@ravnborg.org>]

Hi Linus.

Please pull from:

    ssh://master.kernel.org/pub/scm/linux/kernel/git/sam/kbuild-fixes.git

Following fixes has been collected:

Andi Kleen (1):
      kbuild: disable modpost warnings for linkonce sections

Christophe Jaillet (1):
      kconfig: incorrect 'len' field initialisation ?

Jan Blunck (1):
      Don't clean bounds.h and asm-offsets.h

Masatake YAMATO (1):
      kbuild: escape meta characters in regular expression in make TAGS

Randy Dunlap (1):
      kernel-doc: allow unnamed bit-fields

S.Çağlar Onur (1):
      Remove *.rej pattern from .gitignore

Sam Ravnborg (2):
      MAINTAINERS: document names of new kbuild trees
      kbuild: filter away debug symbols from kernel symbols


The kernel-doc patch is not a real 'fix' as such.
But as the patch most likely does not prevent your systems from
booting I took it here too.

	Sam
