Hey Rusty, Here are a few fixes for virtio and virtio_console. The first patch ensures the data elements of vqs are properly initialised at allocation-time so that we don't trigger BUG_ONs. I found this when hot-unplugging ports and there was just one unused buffer. detach_unused_buffers() kept returning pointers that were invalid. I didn't catch this earlier as I had the in_vq filled

skb_page_frag_refill currently permits only order-0 page allocs unless GFP_WAIT is used. Change skb_page_frag_refill to attempt higher-order page allocations whether or not GFP_WAIT is used. If memory cannot be allocated, the allocator will fall back to successively smaller page allocs (down to order-0 page allocs). This change brings skb_page_frag_refill in line with the existing page allocation

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
