Commit 37487a56 authored Apr 29, 2008 by Christoph Lameter Committed by Linus Torvalds Apr 29, 2008

Add kbuild.h that contains common definitions for kbuild users



The same definitions are used for the bounds logic and the asm-offsets.h
generation by kbuild.  Put them into include/linux/kbuild.h file.

Also add a new feature

	COMMENT("text")

which can be used to insert lines of ocmments into asm-offsets.h and
bounds.h.
