No worry.  Please take your time and let me know if there is anything I can
help.

I think we can improve the user-space tool support better for usability.  For
example, it could find LPAE case, set addr_unit parameter, and convert
user-input and output address ranges on its own.  But hopefully the current
support allows simple tests of the kernel side change, and we could do such
improvement after the kernel side change is made.

Thanks,
SJ
