[openib-general] [PATCH v3] ib_sa: require SA registration

[Roland Dreier]

OK, I added the following to my for-2.6.19 branch.  The differences
from your patch are:

 - CMA can have a static variable (good to avoid clashes with a global
   'sa_client' variable name too)
 - IPoIB does not use multicast module upstream, fix ipoib_multicast.c too.
 - Simplify sa_query.c changes a little.  I don't like the
   "deref_client" name for a function, since it sounds too much like
   dereferencing a pointer rather than dropping a reference.  And I
   also didn't like ib_sa_client_get() having a magic side effect of
   setting query->client.  So I just open-coded more stuff.

How does this look?
