The EKR ring claims a range of 0 to 71 but actually reports
values 1 to 72. The ring is used in relative mode so this
change should not affect users.

Is this not a problem upstream as well? Why not?

If it is, this patch will need to go upstream first, and then it'll get
to stable branches from there.
