Hm, you copied wrong code in an earlier patch in this series which
you fix afterwards. That's not good, fixes, should always come first.
This for example makes it possible to apply the fix to the master
branch and feature additions to -next.
Besides, printing the exact values for the debug case and
size_human_readable otherwise is unnecessary churn. All the
information above can be retrieved using the iomem command
anyway, so removing the code altogether seems more useful.

That's a useful fix. Can we have this as a separate patch?
