Subject: [PATCH 0/8] Virtio-over-PCIe on non-MIC

The Virtio-over-PCIe framework living under drivers/misc/mic/vop implements a
generic framework to use virtio between two Linux systems, given shared memory
and a couple of interrupts.  It does not actually require the Intel MIC
hardware, x86-64, or even PCIe for that matter.  This patch series makes it
buildable on more systems and adds a loopback driver to test it without special
hardware.

Note that I don't have access to Intel MIC hardware so some testing of the
patchset (especially the patch "vop: Use consistent DMA") on that platform
would be appreciated, to ensure that the series does not break anything there.

Vincent Whitchurch (8):
  vop: Use %z for size_t
  vop: Cast pointers to uintptr_t
  vop: Add definition of readq/writeq if missing
  vop: Allow building on more systems
  vop: vringh: Do not crash if no DMA channel
  vop: Fix handling of >32 feature bits
  vop: Use consistent DMA
  vop: Add loopback
