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.

This patch-set is a rework of the patch-set from Sept 25th, hopefully all
review comments has been addressed.

The fist patch is a bugfix and migth be applicable for 3.7.

Thanks,
Sjur

  virtio_console: Free buffer if splice fails
  virtio_console: Use kmalloc instead of kzalloc
  virtio_console: Merge struct buffer_token into struct port_buffer
  virtio_console: Add support for remoteproc serial
