Yet another try with VFIO on SPAPR (server PPC64).
As the previous try was too long time ago, I did not bother with
the change log much as all of this requires review again. Also,
it depends on these 2 patchsets which I cannot get reviewed yet
(keep pinging...):
[PATCH] spapr-iommu: extend SPAPR_TCE_TABLE class
[PATCH 0/4] spapr-pci: prepare for vfio
This does not include VFIO KVM device support as the host kernel
part is not there yet because bigger rework of the host VFIO driver
is going to happen soon.
Alex (Williamson), if you find it possible, please "ack" or "rb" as much
as you can. Thanks!
Changes:
v5:
* rebase on top of the current upstream
v4:
* addressed all comments from Alex Williamson
* moved spapr-pci-phb-vfio-phb to new file
