Add a flush_iotlb_range to allow flushing of an iova range instead of a
full flush in the dma-iommu path.
Allow the iommu_unmap_fast to return newly freed page table pages and
pass the freelist to queue_iova in the dma-iommu ops path.
This patch is useful for iommu drivers (in this case the

An architecture may need to validate the VIRTIO devices features
based on architecture specifics.
Provide a new Kconfig entry, CONFIG_ARCH_HAS_RESTRICTED_MEMORY_ACCESS,
the architecture can select when it provides a callback named
arch_has_restricted_memory_access to validate the virtio device
Hi all,
The goal of the series is to give a chance to the architecture
to validate VIRTIO device features.
in this respin:
I use the original idea from Connie for an optional
arch_has_restricted_memory_access.
I renamed the callback accordingly, added the definition of
If protected virtualization is active on s390, the virtio queues are
not accessible to the host, unless VIRTIO_F_IOMMU_PLATFORM has been
negotiated.
Define CONFIG_ARCH_HAS_RESTRICTED_MEMORY_ACCESS and export
arch_has_restricted_memory_access to fail probe if that's
not the case, preventing a host
