This adds a UIO driver the ivshmem device, found in QEMU and the Jailhouse hypervisor. It exposes the MMIO register region and all shared memory section to userspace. Interrupts are configured in one-shot mode so that userspace needs to re-enable them after each event via the Interrupt Control register. The driver registers all possible MSI-X vectors, coalescing them into the single notifier UIO provides. Note: Specification work for the interface is ongoing, so details may still change.
