Gilbert, same with me, also ubuntu 14.04 -> 16.04.

The patch is already in the 4.7+ kernel tree so it should be in the first 4.7
kernel (pre) release.

I'm not familiar with ubuntu's kernel policy and I also don't know anyone who
does but I guess that the 4.7 kernel will land in  16.10 or 17.04.
Best to ask the Ubuntu Kernelteam.
