This allows to hotplug/unplug PHBs. I could successfully test:
- using in-kernel XICS, emulated XICS and XIVE
- using experimental in-kernel XIVE from Cedric
- hotplug/unplug with e1000 device to validate LSIs
- hotplug/unplug with virtio-net device to validate MSIs
- some simple migration scenarios
Change in v3:
- reworked phandle related code some more
- disintricate allocation/"type setting" of interrupts
- identify LSIs at machine init
Changes in v2:
- rebased on current ppc-for-4.0
- added some preliminary cleanup
- call unrealize from realize error path
- advertise PHB hotplug in last patch
- reworked phandle related code
- sync LSIs to KVM
Please comment.
