Patch series "tools: Fix tools/virtio test build", v2.
This series fixes build failures hit by:
make -C tools/virtio test
Patch 1 adds tools/virtio compatibility definitions needed by current
virtio headers when building the tools/virtio tests. Patch 2 makes
tools/include/linux/overflow.h include stdint.h for SIZE_MAX, which is
used by its size helper functions.
With the series applied, make -C tools/virtio test builds virtio_test,
vringh_test and vhost_net_test successfully.
Tested on x86_64 and arm64 with:
make -C tools/virtio clean
make -C tools/virtio test
This patch (of 2):
vhost_net_test builds virtio_ring.c in userspace.
Recent virtio headers pull in helper headers that are not provided by the
tools/virtio compatibility layer, including asm/percpu_types.h,
linux/completion.h, linux/mod_devicetable.h and linux/virtio_features.h.
Add the missing compat definitions and the DMA attribute used by the
current virtio ring code.

This is the userspace part of the tool: it includes a bunch of stubs for
linux APIs, somewhat simular to linuxsched. This makes it possible to
recompile the ring code in userspace.
A small test example is implemented combining this with vhost_test
module.
