[Jason Gunthorpe <jgg@ualberta.ca>] Global RSA hosts patch
Here's a patch from Jason Gunthorpe that looks generally useful.
It's actually aimed at the Debian LDAP setup, so we can have a file
generated from everyone's ssh_identity data, and still only allow each
person to log in as themselves.
Cheers, Phil.
P.S. I hope the MIME inclusion survives, if not I'll put a copy here:...

[PATCH 22/22] mm: remove the legacy hmm_pfn_* APIs

list?
In any event some of these, like this one, look obvious and I could
still grab a few for hmm.git.
Let me know what you'd like please
