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 userspace builds.

From: Borislav Petkov <bp at suse.de> So tools/ has been growing three, at a different stage of their development export.h headers and so we should unite into one. Add tools/include/ to the include path of virtio and liblockdep to pick the shared header now.

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

Here's a patchset to update tools/virtio with changes in 3.8, as well as the proposed API extension. Useful to see whether the extra level of indirection adds measureable overhead. I will upstream at least patch 1 soon. Michael S. Tsirkin (2): tools/virtio: fix build for 3.8 tools/virtio: update for the new virtio API drivers/vhost/test.c | 4 +++- tools/virtio/Makefile

OK, here is the large patchset that implements the virtio spec update that I sent earlier (the spec itself needs a minor update, will send that out too next week, but I think we are on the same page here already). It supercedes the PUBLISH_USED_IDX patches I sent out earlier. What will follow will be a patchset that actually includes 4 sets of patches. I note below their status. Please consider
