Subject: [PATCH 00/14] tools/virtio: cleanups, fixes

Recent virtio changes brought about build errors for tools/virtio,
as usual. I did some refactoring to hopefully reduce maintainance
load going forward.

Adding stubs is tedious and seemed a perfect fit for cursor -
so I used it for that, then rewrote some commits and accepted
others.  commit logs I've rewritten.

Found and fixed a couple of minor bugs while doing this - that
part's all mine.

Michael S. Tsirkin (14):
  tools/virtio: fix up compiler.h stub
  virtio: make it self-contained
  tools/virtio: use kernel's virtio.h
  tools/virtio: add struct module forward declaration
  tools/virtio: stub DMA mapping functions
  tools/virtio: add dev_WARN_ONCE and is_vmalloc_addr stubs
  tools/virtio: add ucopysize.h stub
  tools/virtio: pass KCFLAGS to module build
  tools/virtio: add struct cpumask to cpumask.h
  tools/virtio: stub might_sleep and synchronize_rcu
  tools/virtio: switch to kernel's virtio_config.h
  virtio_features: make it self-contained
  tools/virtio: fix up oot build
  tools/virtio: add device, device_driver stubs
