[Click] 2.6 Kernel Patch for Click 1.4.3

[Ross C Mcilroy]

Hi Eddie,

Yes, you can definitely include it in Click, that's the reason I posted
it :-).

I'm sure, with some minor tweaking, the patch will also work on the
2.6.10 kernel.   There is not a huge difference between 2.6.9 and 2.6.10
as far as I'm aware (not as big as between 2.4 and 2.6 anyway :-)).

As I mentioned, I've not changed the scripts which create the
elements.mk file, this means it needs to be manually changed to add new
elements.  I've written the example elements.mk file in such a way that
it should be reasonably easy to create with the script, as long as you
know which directory each element comes from.

Let me know if you have any other questions

Ross

Ross,

This is literally fabulous.  Can we include it in Click??  Do you think
the 
patch will work on 2.6.10?

Francis Bogsanyi.  I've managed to get it to work (for what I need
anyway) and thought I would post it.  I noticed there were problems with
sending attachements to this list, so I've put it up on my website
(http://www.dcs.gla.ac.uk/~mcilrorc/stuff.html) along with instructions
on how to use it.

in order to prevent common symbols in the resulting object file, which
modprobe complains about.  Also, I had to remove the ipratemon from the
list of elements which can run under the kernel, since it uses floats,
and so doesn't compile within the kernel build tree.

scripts which create elements.mk, so you'll need to copy it manually
across, and obviously you'll need to modify it if you want to use
different elements.
