[Jason Wessel]

Linus, please pull from the for_linus branch at:

 
git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/linux-2.6-kgdb.git
for_linus

These are the fixes since the initial kgdb merge.

Thanks,
Jason.

So when will we see kgdboe or some other way of getting gdb to connect to the 
target over ethernet upstream?

i think the proper way would be to extend the kgdb-over-console (kgdboc) 
concept and make it easy to utilize the existing netconsole code via 
KGDB. This brings nice synergy: netconsole is utilized by other debug 
infrastructure as well so anything that supports netconsole would 
automatically support KGDB as well. I dont really like the old kgdboe 
approach from a design POV as it created a parallel infrastructure for 
special-purpose kgdb IO.

likewise, the firewire debugging code could/should be extended to create 
a bidirectional console as well - that has other benefits as well. (we'd 
get printks over firewire - instead of the special-purpose firescope 
utility)

and the early console drivers could be reused to do early debugging via 
KGDB as well.

When I looked at the sources right after it was merged this seemed like the 
preferred approach, but I couldn't find any evidence of anyone working on the 
port...  Are you aware of any?
