I picked these up into my staging tree for the tester this morning, 
there's a few hiccups from my latest master merge but they don't seem 
super exciting.  So it might take a bit for these to show up in my 
for-next, but they're headed in that direction.

LMK if you guys were aiming for some other tree, or want to do some sort 
of shared tag for them.  Otherwise they'll show up in linux-next soon.

Thanks!
