This depends on the code gen options we use for kernel and modules, and
where the modules are placed relative to kernel text/data. We either
need to move to other code model options for both kernel and modules
(wastefull), or provide a module_map with a reserved VA range for
loading modules (easy).
A very simple way to reproduce this issue reliably is to move IODEV_BASE
up by some MB and use the new free space for a module_map.
The map is easy to implement, but picking a "proper" VA range is not
that easy. I hope to have a patch (good enough for now) soon, we can
discuss fine tuning later.
