Subject: [PATCH 0/2] virtio_mmio: Fix suspend to disk (hibernation)

At the moment suspend to disk (hibernation) works correctly when using
virtio_pci, but not when using virtio_mmio. This is because virtio_mmio
does not call the freeze/restore callbacks provided by most virtio
drivers.

Fix this by adding the missing PM calls to virtio_mmio and restore
the guest page size for the legacy version of virtio_mmio.

Stephan Gerhold (2):
  virtio_mmio: Add missing PM calls to freeze/restore
  virtio_mmio: Restore guest page size on resume
