[PATCH 00/14] Remove old_portio users for memory region PIO mapping
...how real hardware works and it limits us in the ability to
spawn eventfd''s on PIO ports which doesn''t work with this approach. Instead,
let''s model it more easily. Let''s just map the PIO memory region into MMIO
space.
For this to work, we need to get rid of all old_portio struct users, as they
break with this approach. This is what this patch set does. It also converts
the e500 machines and sPAPR to the new memory region model.
