If you don't want to compile a kernel exclusively for a Sun 3, say N.

This select VIRTIO_MMIO can cause a kconfig warning:
WARNING: unmet direct dependencies detected for VIRTIO_MMIO
Depends on [n]: VIRTIO_MENU [=n] && HAS_IOMEM [=y] && HAS_DMA [=y]
In my repo, VIRTIO_MMIO has no dependency on VIRTIO_MENU:
./drivers/virtio/Kconfig
config VIRTIO_MMIO
tristate "Platform bus driver for memory mapped virtio devices"
depends on HAS_IOMEM && HAS_DMA
Selected by [y]:
- VIRT [=y] && M68KCLASSIC [=y] && MMU [=y]
How do you generate this warning?
The first version of my patch added the VIRTIO_MENU but Geert said it's not necessary because
VIRTIO_MENU defaults to y.

The sentence above needs an ending period ('.').
I agree.
Thanks,
