* parport: Use request_muxed_region for IT87 probe and lockAlan Cox2011-05-06
| | | | | | | | | | | | This is needed as part of making the various IT87 drivers actually co-exist politely with each other, and with other superio devices that may be muxed on 0x2E/0x2F. It can be applied before or after the other patches by Nat Gurumoorthy without problem. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* TTY: serial_core, remove invalid testJiri Slaby2011-04-25
| | | | | | | | | | | | | | | tty->index (named here as line) is set up in initialize_tty_struct. The value is checked in get_tty_driver for the found driver as: if (device < base || device >= base + p->num) continue; *index = device - base; So index/line can never be more than driver->num.

| | | | | | | | | | | | moxa_write can be called from atomic context with irqs disabled (from ppp_async_push).

* Char: nozomi, remove port.count checksJiri Slaby2011-04-25
| | | | | | | | | | | | | | | | | | | | Before 33dd474a, these were some kind of protection against race with HUP. They were protected with port->tty_sem at the same time. By that commit, the counting was switched to tty_port's one, but the locking remained the old one. So the count was not protected by any lock anymore. The driver should not test whether it raced with HUP or not anyways. With the new refcounted tty model, it just should proceed as nothing happened because all needed info is still there. In respect to this, let's drop the useless and unprotected tests (tty_port->count is protected by tty_port->lock).

* tty: Clean console safelyPetr Písař2011-04-19
| | | | | | | | | | | | | | Traditional \E[2J sequence erases console display but scroll-back buffer and underlying device (frame) buffer keep data that can be accessed by scrolling console back. This patch introduce new \E[J parameter 3 that allows to scramble scroll-back buffer explicitly. Session locking programs (screen, vlock) can use it to prevent attacker to browse locked console history.

| | | | | | | | | | | | | | Now, uart_update_termios is empty, so it's time to remove it. We no longer need a live tty in .dtr_rts. So this should prune all the bugs where tty is zeroed in port->tty during tty_port_block_til_ready. There is one thing to note. We don't set ASYNC_NORMAL_ACTIVE now. It's because this is done already in tty_port_block_til_ready.

* serial: core, move termios handling to uart_startupJiri Slaby2011-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | We should not fiddle with speed and cflags in .dtr_rts hook. Actually we might not have tty at that moment already. So move the console cflag copy and speed setup into uart_startup. Actually the speed setup is already there, but we need to call it unconditionally (uart_startup is called from uart_open with hw_init = 0). This means we move uart_change_speed before dtr/rts setup in .dtr_rts. But this should not matter as the setup should be called after uart_change_speed anyway. Before: After: dtr/rts setup (dtr_rts) uart_change_speed (startup) uart_change_speed (update_termios) dtr/rts setup (dtr_rts) dtr/rts setup (update_termios) dtr/rts setup (update_termios) The second setup will dismiss with the next patch.

* serial: altera_uart: Scan for a free port if platform device id is -1Tobias Klauser2011-04-19
| | | | | | | | | | | | | | | | | | Devices extracted from device tree all seem to have pdev->id set to -1. Up until now we mapped all devices with id -1 to the first device. This behaviour could lead to problems when using more than one Altera UART in a system. This patch changes the behaviour of the driver to scan for the next free id in case the id is -1. Because we cannot refer back to the assigned id in altera_uart_remove, the port instance needs to be stored in device drvdata.

| * | Input: add KEY_IMAGES specifically for AL Image BrowserJarod Wilson2011-04-13

At present, remotes with an images or photos or pictures button use any number of different keycodes which sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA, KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right. In my mind, KEY_MEDIA should be something more like a media center application launcher (and I'd like to standardize on that for things like the windows media center button on the mce remotes). KEY_CAMERA is used in a lot of webcams, and typically means "take a picture now". KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION might be the closest fit here, if you think "photo slide show", but it may well be more intended for "run application in full-screen presentation mode" or to launch something like magicpoint, I dunno. And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL Image Browser, the meaning of which I think is crystal-clear. I believe AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser by KEY_VIDEO, so I'm also adding appropriate comments next to those keys.
