Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild 

Pull kbuild changes from Michal Marek:
 - cleanups in the main Makefiles and Documentation/DocBook/Makefile
 - make O=...  directory is automatically created if needed
 - mrproper/distclean removes the old include/linux/version.h to make
   life easier when bisecting across the commit that moved the version.h
   file

* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  kbuild: docbook: fix the include error when executing "make help"
  kbuild: create a build directory automatically for out-of-tree build
  kbuild: remove redundant '.*.cmd' pattern from make distclean
  kbuild: move "quote" to Kbuild.include to be consistent
  kbuild: docbook: use $(obj) and $(src) rather than specific path
  kbuild: unconditionally clobber include/linux/version.h on distclean
  kbuild: docbook: specify KERNELDOC dependency correctly
  kbuild: docbook: include cmd files more simply
  kbuild: specify build_docproc as a phony target
