This patch-set introduces the CAIF Virtio Link layer. The purpose is to communicate with a remote processor (a modem) over shared memory. Virtio is used as the transport mechanism, and the Remoteproc framework provides configuration and management of the Virtio rings and devices. The modem and Linux host may be on the same SoC, or connected over a shared memory interface such as LLI. Zero-Copy

Hi: This series tries to fix various issues of vhost: - Patch 1 adds a missing write barrier between used idx updating and logging. - Patch 2-3 brings back the protection of device IOTLB through vq mutex, this fixes possible use after free in device IOTLB entries. - Patch 4 fixes the diry page logging when device IOTLB is enabled. We should done through GPA instead of GIOVA, this was done

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> This driver depends on Rusty's new host virtio ring implementation, so this patch-set is based on the vringh branch in Rusty's git. Changes since V1: - Use the new iov helper functions, and simplify iov handling. However this triggers compile warnings, as it takes struct iov while kernel api uses struct kiov - Introduced
