Merge branch 'tty-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6
* 'tty-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6: (76 commits) pch_uart: reference clock on CM-iTC pch_phub: add new device ML7213 n_gsm: fix UIH control byte : P bit should be 0 n_gsm: add a documentation serial: msm_serial_hs: Add MSM high speed UART driver tty_audit: fix tty_audit_add_data live lock on audit disabled tty: move cd1865.h to drivers/staging/tty/ Staging: tty: fix build with epca.c driver pcmcia: synclink_cs: fix prototype for mgslpc_ioctl() Staging: generic_serial: fix double locking bug nozomi: don't use flush_scheduled_work() tty/serial: Relax the device_type restriction from of_serial MAINTAINERS: Update HVC file patterns tty: phase out of ioctl file pointer for tty3270 as well tty: forgot to remove ipwireless from drivers/char/pcmcia/Makefile pch_uart: Fix DMA channel miss-setting issue. pch_uart: fix exclusive access issue pch_uart: fix auto flow control miss-setting issue pch_uart: fix uart clock setting issue pch_uart : Use dev_xxx not pr_xxx ... Fix up trivial conflicts in drivers/misc/pch_phub.c (same patch applied twice, then changes to the same area in one branch)

- bool "Virtual terminal" if EXPERT

- default y
- ---help---
- If you say Y here, you will get support for terminal devices with
- display and keyboard devices. These are called "virtual" because you
- can run several virtual terminals (also called virtual consoles) on
- one physical terminal. This is rather useful, for example one
- virtual terminal can collect system messages and warnings, another
- one can be used for a text-mode user session, and a third could run
- an X session, all in parallel. Switching between virtual terminals
- is done with certain key combinations, usually Alt-<function key>.
-
- The setterm command ("man setterm") can be used to change the
- properties (such as colors or beeping) of a virtual terminal. The
- man page console_codes(4) ("man console_codes") contains the special
- character sequences that can be used to change those properties
- directly. The fonts used on virtual terminals can be changed with
- the setfont ("man setfont") command and the key bindings are defined
- with the loadkeys ("man loadkeys") command.
-
- You need at least one virtual terminal device in order to make use
- of your keyboard and monitor. Therefore, only people configuring an
- embedded system would want to say N here in order to save some
- memory; the only way to log into such a system is then via a serial
- or network connection.
-
- If unsure, say Y, or else you won't be able to do much with your new
- shiny Linux system :-)

-config VT_CONSOLE
- bool "Support for console on virtual terminal" if EXPERT
- depends on VT
- default y
- ---help---
- The system console is the device which receives all kernel messages
- and warnings and which allows logins in single user mode. If you
- answer Y here, a virtual terminal (the device used to interact with
- a physical terminal) can be used as system console. This is the most
- common mode of operations, so you should say Y here unless you want
- the kernel messages be output only to a serial port (in which case
- you should say Y to "Console on serial port", below).
-
- If you do say Y here, by default the currently visible virtual
- terminal (/dev/tty0) will be used as system console. You can change
- that with a kernel command line option such as "console=tty3" which
- would use the third virtual terminal as system console. (Try "man
- bootparam" or see the documentation of your boot loader (lilo or

+ ---help---
+ This option supports the 2232 7-port serial card shipped with the
+ Amiga 2000 and other Zorro-bus machines, dating from 1989. At
+ a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
+ each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
+ ports were connected with 8 pin DIN connectors on the card bracket,
+ for which 8 pin to DB25 adapters were supplied. The card also had
+ jumpers internally to toggle various pinning configurations.
+
+ This driver can be built as a module; but then "generic_serial"
+ will also be built as a module. This has to be loaded before
+ "ser_a2232". If you want to do this, answer M here.
+
+config SX
+ tristate "Specialix SX (and SI) card support"
+ depends on SERIAL_NONSTANDARD && (PCI || EISA || ISA) && BROKEN
+ help
+ This is a driver for the SX and SI multiport serial cards.
+ Please read the file <file:Documentation/serial/sx.txt> for details.
+
+ This driver can only be built as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module will be called sx. If you want to do that, say M here.
+
+config RIO
+ tristate "Specialix RIO system support"
+ depends on SERIAL_NONSTANDARD && BROKEN
+ help
+ This is a driver for the Specialix RIO, a smart serial card which
+ drives an outboard box that can support up to 128 ports. Product
+ information is at <http://www.perle.com/support/documentation.html#multiport>.
+ There are both ISA and PCI versions.
+
+config RIO_OLDPCI
+ bool "Support really old RIO/PCI cards"
+ depends on RIO
+ help
+ Older RIO PCI cards need some initialization-time configuration to
+ determine the IRQ and some control addresses. If you have a RIO and
+ this doesn't seem to work, try setting this to Y.

+config VT
+ bool "Virtual terminal" if EXPERT

+ select INPUT
+ default y
+ ---help---
+ If you say Y here, you will get support for terminal devices with
+ display and keyboard devices. These are called "virtual" because you
+ can run several virtual terminals (also called virtual consoles) on
+ one physical terminal. This is rather useful, for example one
+ virtual terminal can collect system messages and warnings, another
+ one can be used for a text-mode user session, and a third could run
+ an X session, all in parallel. Switching between virtual terminals
+ is done with certain key combinations, usually Alt-<function key>.
+
+ The setterm command ("man setterm") can be used to change the
+ properties (such as colors or beeping) of a virtual terminal. The
+ man page console_codes(4) ("man console_codes") contains the special
+ character sequences that can be used to change those properties
+ directly. The fonts used on virtual terminals can be changed with
+ the setfont ("man setfont") command and the key bindings are defined
+ with the loadkeys ("man loadkeys") command.
+
+ You need at least one virtual terminal device in order to make use
+ of your keyboard and monitor. Therefore, only people configuring an
+ embedded system would want to say N here in order to save some
+ memory; the only way to log into such a system is then via a serial
+ or network connection.
+

+ depends on VT
+ default y
+ ---help---
+ The system console is the device which receives all kernel messages
+ and warnings and which allows logins in single user mode. If you
+ answer Y here, a virtual terminal (the device used to interact with
+ a physical terminal) can be used as system console. This is the most
+ common mode of operations, so you should say Y here unless you want
+ the kernel messages be output only to a serial port (in which case
+ you should say Y to "Console on serial port", below).
+
+ If you do say Y here, by default the currently visible virtual
+ terminal (/dev/tty0) will be used as system console. You can change
+ that with a kernel command line option such as "console=tty3" which
+ would use the third virtual terminal as system console. (Try "man
+ bootparam" or see the documentation of your boot loader (lilo or
+ loadlin) about how to pass options to the kernel at boot time.)

+ 1 console driver is enabled, setting this to 'y' will allow you to
+ select the console driver that will serve as the backend for the

+ A pseudo terminal (PTY) is a software device consisting of two

+ a physical terminal; the master device is used by a process to
+ read data from and write data to the slave, thereby emulating a
+ terminal. Typical programs for the master side are telnet servers
+ and xterms.
+
+ Linux has traditionally used the BSD-like names /dev/ptyxx for
+ masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
+ has a number of problems. The GNU C library glibc 2.1 and later,
+ however, supports the Unix98 naming standard: in order to acquire a
+ pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
+ terminal is then made available to the process and the pseudo
+ terminal slave can be accessed as /dev/pts/<number>. What was
+ traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
