It's maintained at SourceForge:

	http://sourceforge.net/projects/kgdb

Patches can be downloaded from:
	
	http://sourceforge.net/project/showfiles.php?group_id=5073

I suspect that you will likely want to add yourself to the
kgdb-bugreport mailing list.

	https://lists.sourceforge.net/lists/listinfo/kgdb-bugreport

Mailing list is acting up; I've been having trouble posting due to
a mailserver problem; I contacted the SourceForge folks about it.

Andrew Morton has recently been taking snapshots and including them
in his mm series. It would be nice to get in "in order" and ready
for being merged up into the linux tree. When I applied the 2.6.13
patch I think I noticed some '#ifdef KGDB' code missing. I'd like 
to see the patch totally disabled by not configuring KGDB. The 
patch instructions are also a bit misleading, at least for 2.6.13;
I had to apply all of the patches in the series to avoid a lot a 
patch rejects.

2.6.16.x is a branch, based on 2.6.16.

2.6.17-rcX is on the trunk.  The published diffs are against 2.6.16.

So you should have patched 2.6.16.

Nobody is doing the work to get the patches in order and merged up.  It'd
require a month or two moderately intense effort.
