Hello,

here is the patch I posted previously that adds support for modversions
in external kernel modules that are built outside the main kernel tree
(first posting archived here: http://lwn.net/Articles/69148/). Relative
to the original version, the attached version also works when compiling
with O=.

The patch also adds a modules_add target that does the equivalent of
modules_install for one external module. In addition, it makes clean and
mrproper work for external modules. Makefiles of modules that live
outside the main tree currently need to provide their own clean targets
to remove the files kbuild creates; this is pretty messy.

The third change is to remove one instance of temporary file creation
inside the main kernel tree while external modules are built. I think
there are still other cases where temp files in the kernel tree are
used. IMHO they should all go away, so that a ``make -C $KERNEL_SOURCE
modules SUBDIRS=$PWD'' works against a read-only tree.


Thanks,
