Endianness issues are now consistent as per the documentation in host/mic_virtio.h. Note that the host can be both BE or LE whereas the card is always LE. Memory space sparse warnings are fixed for now by using __force. This is sufficient for now since the driver depends on x86 but will need to be revisited if we support other architectures which treat I/O memory differently from system memory.

From: Ashutosh Dixit <ashutosh.dixit at intel.com> This patch introduces the host "Virtio over PCIe" interface for Intel MIC. It allows creating user space backends on the host and instantiating virtio devices for them on the Intel MIC card. A character device per MIC is exposed with IOCTL, mmap and poll callbacks. This allows the user space backend to: (a) add/remove a virtio

From: Ashutosh Dixit <ashutosh.dixit at intel.com> This patch introduces the card "Virtio over PCIe" interface for Intel MIC. It allows virtio drivers on the card to communicate with their user space backends on the host via a device page. Ring 3 apps on the host can add, remove and configure virtio devices. A thin MIC specific virtio_config_ops is implemented which is borrowed

Replace duplicated code in all transports with a single wrapper in virtio.c. The only functional change is in virtio_mmio.c: if a buggy device sends us an interrupt before driver is set, we previously returned IRQ_NONE, now we return IRQ_HANDLED. As this must not happen in practice, this does not look like a big deal. See also commit 3fff0179e33cd7d0a688dab65700c46ad089e934 virtio-pci: do not
