Subject: [PATCHv6 0/3] virtio_console: Add rproc_serial device

From: Sjur Brændeland <sjur.brandeland@...ricsson.com>

I thought rebasing rproc_serial to linux-next was going to be trivial.
But when starting the merge I realized that I had to refactor the
the patches from  Masami Hiramatsu. The splice support has the same issue
as I faced, with different type of buffers in the out_vq.
So I ended up refactoring the splice functionality. The code
size got smaller so hopefully this a step in the right direction.

This refactoring also make introduction of rproc_serial cleaner.

As requested I also added a patch for not initializing buffers.

I have tested the VIRTIO_CONSOLE device by looping large amount of data
through character device and tty, with lockdep and slub-debug on.
This looks stable for me. I've also done a simple test of splice.

Thanks,
Sjur
