Looking back, this is pretty much two series squashed that could be

Indeed.

I couldn't work out the link between the first 5 patches and the last 2
until I read this...

Is anything in the 01->05 patch set even related to kgdb? From the stack
traces it looks to me like the lock dep warning would trigger for any
sysrq. I think separating into two threads for v2 would be sensible.


Daniel.

For all serial patches I'd expect them to go through the tty tree once
they've been reviewed.

If folks are OK w/ the 'smp' patch it probably should go in some core
kernel tree.  The kgdb patch won't work without it, though, so to land
that we'd need coordination between the folks landing that and the
folks landing the 'smp' patch.
