this is the commit I'm talking about; I think it went into 2.6.21 but
I'm not sure. Anyway it seems it should make sure that the tid
member is aligned to 8 bytes, or at least I think it should:

IB: Make sure struct ib_user_mad.data is aligned
Make the untyped data region in ib_user_mad have type u64 so that it
gets aligned properly. This avoids alignment faults in ib_umad when
casting the data field to an rmpp_mad and accessing the 64-bit tid
field on architectures like ia64.
