I just posted a new/improved patch at

I'm not really planning on working much more on KDB, I just
needed a couple of features out of it, and that's what this
patch provides.

I haven't tried poll_funcs with hvc consoles, etc;
it may need fixes there. Or maybe not, I don't know.

I haven't done any of this, I haven't even looked at it.
The patch that I mailed out "worked for me" so I didn't dig any deeper.
If this needs to be done, then do it; I'm not planning to.

Another area that needs fixing: the way that TCE's work has
changed completely in recent kernels, and so I just stubbed out
the 'examine tce' routine.  This needs to be fixed.
