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
