similar to: [PATCH] virtio: Add module driver macro for virtio drivers.

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. Signed-off-by: Sjur Br?ndeland <sjur.brandeland at stericsson.com> --- Hi

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> Allow rproc serial ports to receive data before the port is connected. Rproc serial ports usually talk to very simple remote devices with no control queue managing open/close events. So we must let remote devices write to the virtio ring even if the device is not yet fully initialized. Signed-off-by: Sjur Br?ndeland

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: 62031b28: [<6026085d>] panic+0x16b/0x2d3 62031b30:

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.

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> Add wrappers for the host vrings to support loose coupling between the virtio device and driver. A new struct vringh_config_ops with the functions find_vrhs() and del_vrhs() is added to the virtio_device struct. This enables virtio drivers to manage virtio host rings without detailed knowledge of how the vrings are created and

Rproc_serial communicates with remote processors that may crash and leave buffers in the out-queue.
