Hmm, it will blow out the host size ... although that's not such a huge problem since there are relatively few of them in most running kernels. What's the actual use case for this, though? The host structure is allocated in ordinary memory ... we don't make sure it's DMAable, and most HBAs that want to use memory for mailboxes need coherent memory anyway.
