This issue is fixed in 4.19-rc1.
If you don't want to pull the latest, here is the change you need to
cherry-pick to your branch.

Paul, I think we need this in 4.18-stable.
Also Palmer, I think we should pick it up in riscv-linux-4.18.
The mainline commit is:

OK, it backports cleanly and passes a short rcutorture test. You guys
have tested it, correct? If so, I am happy to pass it on to -stable.
Thanx, Paul

Hi Paul,
I had it tested on top of 4.18-rc8 with RISC-V board (HighFive Unleashed).
I can try again on 4.18-stable if required.

Hello, Atish,
Please do test it on 4.18-stable. The -stable maintainers get
understandably annoyed when given non-working backports. ;-)
