linux/drivers/char, branch v3.8-rc3

Drivers: char: remove __dev* attributes.

2013-01-03T23:57:15Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

virtio_console: Add support for remoteproc serial

2012-12-18T04:50:44Z

Add a simple serial connection driver called VIRTIO_ID_RPROC_SERIAL (11) for communicating with a remote processor in an asymmetric multi-processing configuration. This implementation reuses the existing virtio_console implementation, and adds support for DMA allocation of data buffers and disables use of tty console and the virtio control queue.

virtio_console: Merge struct buffer_token into struct port_buffer

2012-12-18T04:50:44Z

Refactoring the splice functionality by unifying the approach for sending scatter-lists and regular buffers. This simplifies buffer handling and reduces code size. Splice will now allocate a port_buffer and send_buf() and free_buf() can always be used for any buffer. Signed-off-by: Sjur Brændeland Acked-by: Amit Shah Signed-off-by: Rusty Russell

virtio_console: Free buffers from out-queue upon close

2012-12-18T04:50:41Z

Free pending output buffers from the virtio out-queue when host has acknowledged port_close. Signed-off-by: Sjur Brændeland Signed-off-by: Rusty Russell (rebased & cut down)

virtio_console: Use kmalloc instead of kzalloc

2012-12-18T04:50:39Z

Avoid the more cpu expensive kzalloc when allocating buffers. Originally kzalloc was intended for isolating the guest from the host by not sending random guest data to the host. But device isolation is not yet in place so kzalloc is not really needed. Signed-off-by: Sjur Brændeland Signed-off-by: Rusty Russell
