kib cfe7aa28cb Add ioctl to conveniently mmap a PCI device BAR into userspace. ... Add the ioctl PCIOCBARMMAP on /dev/pci to conveniently create userspace mapping of a PCI device BAR. This is enormously superior to read the BAR value with PCIOCREAD and then try to mmap /dev/mem, and should allow to automatically activate the mapped BARs when needed in future. Current implementation creates new sg pager for each user mmap request. If the pointer (and reference) to a managed device pager is stored in pci_map, we would be able to revoke all mappings on the BAR deactivation or relocation. This is related to the unimplemented BAR activation on mmap, and is postponed for the future.
