[ofa-general] XRC merging status

[Roland Dreier]

I've been working on merging the XRC patch set.  I've made a little
progress -- I resplit the core patches so I could understand them (and
fixed a few bugs in the process).  The kernel receive QP and mlx4
changes still need review, and I'm hoping that the kernel receive QP
stuff can be made simpler (at least the mlx4 part).

Anyway, here's what I have so far; build tested only at this point.
I think these three patches are ready to queue for 2.6.28, and I don't
see any fundamental issue with merging the rest -- I just want to
understand things in detail, and that takes time.
