[Qemu-devel] [PATCHv3 0/7] VFIO extensions to allow VFIO devices on spapr-pci-host-bridge

[David Gibson]

Hi Alex,

Here are the parts of my recent series to allow VFIO devices on the
spapr-pci-host-bridge device which affect the core VFIO code.  They've
been revised according to the comments from yourself and others.

There's also one patch for the memory subsystem.

Note that while these are motivated by the needs of the sPAPR code,
they changes should all be generally correct, and will allow safer and
more flexible use of VFIO devices in other potential situations as
well.

Please apply.

Changes since v2:
  * Reworked IOMMU notifier replay mechanism according to Paolo's
    suggestions.
Changes since v1:
  * Assorted minor cleanups based on comments.
