[PATCH 0/3] virtio-iommu: Support VIRTIO_IOMMU_F_BYPASS_CONFIG

[Jean-Philippe Brucker]

Replace the VIRTIO_IOMMU_F_BYPASS feature with
VIRTIO_IOMMU_F_BYPASS_CONFIG, which enables a config space bit to switch
global bypass on and off.

Add a boot-bypass option, which defaults to 'on' to be in line with
other vIOMMUs and to allow running firmware/bootloader that are unaware
of the IOMMU.

See the spec change for more rationale

Jean-Philippe Brucker (3):
  NOMERGE: virtio-iommu: Add definitions for
    VIRTIO_IOMMU_F_BYPASS_CONFIG
