[PATCH v3 0/2] tools: Fix tools/virtio test build

[Yichong Chen <chenyichong@uniontech.com>]

Hi,

This series fixes build failures hit by:

  make -C tools/virtio test

It is based on linux-next commit:

  commit 3d5670d672ae ("Add linux-next specific files for 20260626")

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

Changes in v3:
- Move the stdint.h include inside the overflow.h include guard, as SJ
  suggested.
- Add Tested-by from SJ Park to patch 1.

Changes in v2:
- Rebase and retest on linux-next.
- Add the missing asm/percpu_types.h compat header reported by Eugenio.
- Keep the tools/virtio compat definitions aligned with current
  virtio_features.h helpers.
- Drop the slab.h kmalloc_obj/kmalloc_objs change because linux-next
  already defines them in tools/virtio/linux/kernel.h.
