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.

thanks,
