I cannot readily explain the above email glitch, but I did just now switch
back to mailgw.nvidia.com for this patchset, in order to get the nice behavior
of having "From:" really be my native NVIDIA email address. That's very nice,
but if the glitches happen again, I'll switch back to using gmail for
git-send-email.

Sorry about the weirdness. It does still let you apply the patch, I
just now checked on that.


Hi Ira, could you please let me know if you'd like me to repost this patch, or
the entire patchset, or if you're able to deal with it as-is? As it stands, the
DKIM-Signature cruft above needs to be manually removed, either from the patch, or
from the commit log after applying the patch.

Also, as noted in the email thread involving Bharath and sgi-gru [1], I'm
currently planning on branching from your tree, and continuing the misc
call site conversions from there. And then just adapting to whatever API
changes are made to vaddr_*() functions. And the biovec call site conversions should
be based on that as well.
