kbuild: patch to Documentation/kbuild/modules.txt
First off, thanks for the kbuild docs, they are very useful! Second, I've attached a patch to modules.txt (from 2.6.14.2) with a "compile" fix to a Makefile example, and some trivial spelling/grammar nits. Please let me know if you want the patch in some other format (eg not MIME), or if I should go bother someone else about it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
