I'm not sure if you'll need this, but I've updated the two multicast patches in
my for-roland branch based on a couple of comments.  All changes are minor.

* Converted a list_del/list_add combo to list_move.
* Changed a couple of kzalloc calls to kmalloc.
* Modified ib_sa_get_mcmember_rec to no longer return default MCMemberRecord
settings.

The for-roland branch is based on the tip of Linus' tree from two days ago, but
I re-tested the changes against 2.6.20.

If there's an easier way for you to handle these types of updates, just let me
know.
