Both patches

I'd suggest you send a pull request with these two patches on top of 4.4-rc1,
and then either Vinod or I send it to Linus, and you base your other changes
on top of the same branch.

I think Vinod's tree is slightly more fitting for the 4.4 merge, but if he
prefers me to take them instead, I will.
