Note this does not affect the ABI - ib_user_mad format stays the same,
the only effect this has is in how ib_user_mad is placed within larger
kernel-only structures.

So this makes sense to me, and I think this is small enough to be 2.6.20 material.
Sean? Roland?

Jason, while the patch is a one-liner, I think you should
indicate that you can certify the Developer's Certificate of Origin 1.1
