Jason Gunthorpe bb3130192f vfio-pci: Use io_remap_pfn_range() for PCI IO memory ... [ Upstream commit 7b06a56d468b756ad6bb43ac21b11e474ebc54a0 ] commit f8f6ae5d077a ("mm: always have io_remap_pfn_range() set pgprot_decrypted()") allows drivers using mmap to put PCI memory mapped BAR space into userspace to work correctly on AMD SME systems that default to all memory encrypted. Since vfio_pci_mmap_fault() is working with PCI memory mapped BAR space it should be calling io_remap_pfn_range() otherwise it will not work on SME systems.
