Why didn't you implement this function for ARM?

Because unfortunately I don't have an ARM setup to test it on and I
thought it would be unfair to publish the patch with untestable ARM support.

So what's the plan? Who will implement the ARM solution?

I don't think there is a technical challenge to implement the ARM one.
