[PATCH] virtio_console: Initialize guest_connected=true for rproc_serial
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
When rproc_serial is initialized, guest_connected should be set
to true. We can then revert the extra checks introduced in
commit: "virtio_console: Let unconnected rproc device receive data."

[PATCH] Revert "virtio_console: Initialize guest_connected=true for rproc_serial"
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
This reverts commit 8078db789a92b10ff6e2d713231b5367e014c53b.
The reverted patch caused opening of ports to fail for rproc_serial.
In probe guest_connected was set to true, but port_fops_open()
fails with -EMFILE if guest_connected already is true.

[PATCHv7 0/4] virtio_console: Add rproc_serial driver
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
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.

[PATCHv6 0/3] virtio_console: Add rproc_serial device
From: Sjur Br?ndeland <sjur.brandeland at stericsson.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

[PATCH] virtio_console: Use virtio device index to generate port name
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Use virtio device index for creating unique device port names.
Current index allocation in virtio is based on a monotonically
increasing variable "index". A better handling of this is to
use device index which is allocated by ida.

[PATCHv2 vringh 0/3] Introduce CAIF Virtio driver
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

[PATCH] virtio_console: Don't access uninitialized data.
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Don't access uninitialized work-queue when removing device.
The work queue is initialized only if the device multi-queue.
So don't call cancel_work unless this is a multi-queue device.
This fixes the following panic:
Kernel panic - not syncing: BUG!
Call Trace:
