Here's what I see:

ip_ib_mc_map() is called directly from cma_join_ib_multicast(), which is
added to the ofed_1_2 cma.c via patch file:
kernel_patches/fixes/sean_multicast_1.patch

So when I compiled ofed_1_2 on rhel4u4, the cma wouldn't load because
there is no ip_ib_mc_map() in rhel4u4.  

So you need a backport patch for this to work on rhel4u4.  Probably many
of the older kernels.
