We would have to make that pSeries specific for now I suppose... We don't have a way to know that there "can" be an EHEA right ? It may not be in the device-tree at boot and dynamically added to the partition... And we can't dynamically "demote" the ioremap area like we do for userspace as we have no tracking of bolted entries hashed in early during boot (I plan to fix that but that will take a while).
