Commit 06300b21f4c7 ("kbuild: support building individual files for
external modules") introduced the '/' target. It works only for
external modules to build all .o files, but skip the modpost stage.
However, 'make /' looks a bit weird to me. 'make ./' is more sensible
if you want to build all objects under the current directory, and it
works as expected.
Let's change '/' into a phony target that is an alias of './', but
I may feel like deprecating it in the future.

A few modifications done for consistency, such as adding the shell
prompt for command line examples and trailing slash for directories.
Also corrects the module include header and fixes a few grammar
issues that I introduced.

A follow-up to my edit of the first 4 sections.
Shift sections down by one due to the deletion of section 3; grammar
corrections along with some rewording; margin width cleanup; and
change EXTRA_CFLAGS -> ccflags-y.

Omit needless words and sentences; reorganize and tighten sentence structure;
swap sections 2.2 and 2.3 for a more logical flow; remove section 3, therefore
shifting 4->3; add to explanations; and add section on building multiple modules.

The text always mentions ...bin.o_shipped, just the example makefiles
actually use ...bin_shipped. It was corrected in one place some time
ago, these ones seem to have been forgotten.

This patch adds a new (Kbuild) Makefile variable KBUILD_EXTRA_SYMBOLS.
The space separated list of file names assigned to KBUILD_EXTRA_SYMBOLS
is used when calling scripts/mod/modpost during stage 2 of the Kbuild
process for non-kernel-tree modules.

With following patch a second option is enabled to obtain
symbol information from a second external module when a
external module is build.
The recommended approach is to use a common kbuild file but
that may be impractical in certain cases.
With this patch one can copy over a Module.symvers from one
external module to make symbols (and symbol versions) available
for another external module.

Support building individual files when dealing with separate modules.
So say you have a module named "foo" which consist of two .o files bar.o
and fun.o.
You can then do:
make -C $KERNELSRC M=`pwd` bar.o
make -C $KERNELSRC M=`pwd` bar.lst
make -C $KERNELSRC M=`pwd` bar.i
make -C $KERNELSRC M=`pwd` / <= will build all .o files
and link foo.o
make -C $KERNELSRC M=`pwd` foo.ko <= will build the module
and do the modpost step
to create foo.ko
The above will also work if the external module is placed in a
subdirectory using a hirachy of kbuild files.
Thanks to Andreas Gruenbacher <agruen@suse.de> for initial feature
request / bug report.

Update modules.txt with info how to build external modules
with files in several directories.
The question popped up on lkml often enough to warrant this,
let's see if people read this stuff - or google hits it.

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.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
