Hello, This series adds resize support for multiple console ports. The size for each console is stored in its structure and the host informs the guest about size changes via the VIRTIO_CONSOLE_RESIZE control message. This is easily tested by the qemu patches provided by Kusanagi Kouichi with some updates, which I will shortly send to the qemu-devel list. Please apply, Amit. Amit Shah (3):

This patch-set introduces a new virtio type "rproc_serial" for communicating with remote processors over shared memory. The driver depends on the the remoteproc framework. As preparation for introducing "rproc_serial" I've done a refactoring of the transmit buffer handling. NOTE: These two patches are identical to first two patches of the V8 patch-set, but are rebased to
