Merge tag 'vfio-v4.4-rc1' of git://github.com/awilliam/linux-vfio
Pull VFIO updates from Alex Williamson:
- Use kernel interfaces for VPD emulation (Alex Williamson)
- Platform fix for releasing IRQs (Eric Auger)
- Type1 IOMMU always advertises PAGE_SIZE support when smaller mapping
sizes are available (Eric Auger)
- Platform fixes for incorrectly using copies of structures rather than
pointers to structures (James Morse)
- Rework platform reset modules, fix leak, and add AMD xgbe reset
module (Eric Auger)
- Fix vfio_device_get_from_name() return value (Joerg Roedel)
- No-IOMMU interface (Alex Williamson)
- Fix potential out of bounds array access in PCI config handling (Dan
Carpenter)
