similar to: [PATCH] vhost/test: fix up after API change

Allow building vringh without IOTLB (that's the case for userspace builds, will be useful for CAIF/VOD down the road too). Update for API tweaks. Don't include vringh with kernel builds.

This implements a virtio simulator: - adds stubs for enough support functions to compile virtio ring in userspace. - Adds a stub vhost based module this can talk to. This should help us decide things like which ring layout works best. Communication is currently done using an eventfd descriptor. This means there's a shared spinlock there: what I would like to do in the future, is run

Fix it by: 1) switching to use the new device specific fields per vq 2) not including vhost.c, instead make vhost-test.ko depend on vhost.ko. --- drivers/vhost/test.c | 37 +++++++++++++++++++++++++------------ 1 file changed, 25 insertions(+), 12 deletions(-) diff --git a/drivers/vhost/test.c b/drivers/vhost/test.c index 1ee45bc..dc526eb 100644 --- a/drivers/vhost/test.c +++
