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) * tag 'vfio-v4.4-rc1' of git://github.com/awilliam/linux-vfio: vfio/pci: make an array larger vfio: Include No-IOMMU mode vfio: Fix bug in vfio_device_get_from_name() VFIO: platform: reset: AMD xgbe reset module vfio: platform: reset: calxedaxgmac: fix ioaddr leak vfio: platform: add dev_info on device reset vfio: platform: use list of registered reset function vfio: platform: add compat in vfio_platform_device vfio: platform: reset: calxedaxgmac: add reset function registration vfio: platform: introduce module_vfio_reset_handler macro vfio: platform: add capability to register a reset function vfio: platform: introduce vfio-platform-base module vfio/platform: store mapped memory in region, instead of an on-stack copy vfio/type1: handle case where IOMMU does not support PAGE_SIZE size VFIO: platform: clear IRQ_NOAUTOEN when de-assigning the IRQ vfio/pci: Use kernel VPD access functions vfio: Whitelist PCI bridges
