Hi David,

This patch has already been merged into Linus tree. The other two (2/3
and 3/3) still need to be reviewed.

I'm not sure how this works when series touch multiple subsystems --
that is, these changes should go through your tree or Steve's?

Please let me you know if you need anything else.

Thanks!
Paulo
