Okay, this should fix the issue...  I've only compile tested it so far.
Rob, as you have a way to trigger this easily, can you give this patch
a go and let me know if it solves your problem?  Thanks.

Russell, can you let me know the status of this patch? I don't see it in
your tree, and I think I might have missed a followup patch from you? It
seems to solve a real problem with in-kernel faults during the dump_mem
in general, even beyond just an alignment fault.

I was waiting for someone to say "I saw a problem and it works"...
Would be nice to have a Tested-by tag against it...

I've poked at the patch, made one against Fedora, and asked someone in
my team to do a scratch build and test on our local highbank/other
systems. We'll come back with that tag for ya asap, thanks!

Jon.
