Subject: [PATCH v3 0/4] Virtio-over-PCIe loopback

This adds a loopback driver to be able to use/test/evaluate the
drivers/misc/mic/vop/ code without special hardware.

See v1 for more info:
https://lore.kernel.org/lkml/20190116163253.23780-1-vincent.whitchurch@axis.com/

v3:
- Rebase on top of merged patches
- Resend since last posting had duplicate patches

v2:
- Rebase on top of the patches which have merged
- Use unsigned long instead of uintptr_t
- Drop "Use consistent DMA" for now since it's not needed for loopback
- Add race fix
- Build on all architectures, not just ARM and x86
- Add sample userspace code

Vincent Whitchurch (4):
  mic: vop: Fix init race with shared interrupts
  mic: vop: Add loopback driver
  samples: mic: Split out vop code from mpssd
  samples: mic: Add sample VOP userspace
