[RFC 0/5] NVMe passthrough: Support 64kB page host

[Eric Auger]

This series allows NVMe passthrough on aarch64 with 64kB page host.
Addresses and sizes of buffers which are VFIO DMA mapped are
aligned with the host page size.

nvme_register_buf() path is taken care of in this series
but it does not seem to prevent the use case from working.

Best Regards

Eric
