We try using cancel_delayed_work_sync() to prevent the work from
enabling NAPI. This is insufficient since we don't disable the source
of the refill work scheduling. This means an NAPI poll callback after
cancel_delayed_work_sync() can schedule the refill work then can
re-enable the NAPI that

The first 3 patches fix various problems I have encountered with
virtio_test (they may go without this series, but I included to allow you
to test the series).
Patch 4 is in preparation of patch 5, moving the feature negotiation when
we initialize the device.
Patch 5 add the support of
Fix the build caused by the following changes:
- phys_addr_t is now defined in tools/include/linux/types.h
- dev_warn_once() is used in drivers/virtio/virtio_ring.c
- linux/uio.h included by vringh.h use INT_MAX defined in limits.h

Adding $(srctree) on the included path we can build vhost_test
also when the kernel is not built in the source tree (make O=...).
Use of EXTRA_CFLAGS is deprecated, so let's use ccflags-y.

This adds a test module for vhost-vdpa infrastructure to be used
with virtio_test.
Intentionally not tied to kbuild to prevent people from installing
and loading it accidentally.

The feature negotiation are per device, so it' s better to move them
earlier in vdev_info_init() since vhost_vq_setup() contains the code
to initialize virtqueue.

The new --vdpa parameter can be used to run virtio_test with
the new vdpa_sim_test.ko that implements the device.
The main differences with vhost_test are:
- control of status register
- dma map messages
- VHOST_SET_MEM_TABLE not supported by vhost-vdpa
- VHOST_TEST_RUN not supported by
