Hi,
I took a quick look at the dpdk vfio code and spotted an invalid
assumption that should probably be corrected ASAP. That is:
lib/librte_eal/linuxapp/eal/eal_vfio.h:
#define VFIO_GET_REGION_ADDR(x) ((uint64_t) x << 40ULL)
#define VFIO_GET_REGION_IDX(x) (x >> 40)
Region offset to index is an
itself.

v4: Fix build without CONFIG_VFIO_NOIOMMU (oops). Also avoid local
noiommu variable in vfio_create_group() to avoid scope confusion
with global of the same name.

v3: Version 2 was dropped from kernel v4.4 due to lack of a user. We
now have a working DPDK port to this interface, so I'm proposing
