I'll be posting an update to the -mm tree soon.  Presently, I have been
updating the x86 patch set because the x86 developers provided some
insight as to what needed to change to gain adoption into the mainline
kernel.


See:
http://git.kernel.org/?p=linux/kernel/git/jwessel/linux-2.6-kgdb.git;a=shortlog;h=for_x86

Right now the scope is only 8 patches worth.  The other archs will be
patched in when I move the patches forward against the -mm tree.

If you or anyone else would like to help, I'll be happy to forward a
copy of the todo list :-)

Thanks,
Jason.
