[PATCH] sh: various fixes

From: Paul Mundt <lethal@linux-sh.org>

This is the rest of the sh update, which includes everything else
sh-specific, general cleanups, bugfixes, etc.  Nothing really eventful.

-config VT
-	bool "Virtual terminal"
-	---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"
-	depends on VT
-	---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.)
-
-	  If unsure, say Y.
-
-config HW_CONSOLE

-
-config SERIAL
-	tristate "Serial (8250, 16450, 16550 or compatible) support"
-	---help---
-	  This selects whether you want to include the driver for the standard
-	  serial ports.  The standard answer is Y.  People who might say N
-	  here are those that are setting up dedicated Ethernet WWW/FTP
-	  servers, or users that have one of the various bus mice instead of a
-	  serial mouse and don't intend to use their machine's standard serial
-	  port for anything.  (Note that the Cyclades and Stallion multi
-	  serial port drivers do not need this driver built in for them to
-	  work.)
-
-	  To compile this driver as a module, choose M here: the
-	  module will be called serial.
-	  [WARNING: Do not compile this driver as a module if you are using
-	  non-standard serial ports, since the configuration information will
-	  be lost when the driver is unloaded.  This limitation may be lifted
-	  in the future.]
-
-	  BTW1: If you have a mouseman serial mouse which is not recognized by
-	  the X window system, try running gpm first.
-
-	  BTW2: If you intend to use a software modem (also called Winmodem)
-	  under Linux, forget it.  These modems are crippled and require
-	  proprietary drivers which are only available under Windows.
-
-	  Most people will say Y or M here, so that they can use serial mice,
-	  modems and similar devices connecting to the standard serial ports.
-
-config SH_SCI
-	tristate "Serial (SCI, SCIF) support"
-	help
-	  Selecting this option will allow the Linux kernel to transfer data
-	  over SCI (Serial Communication Interface) and/or SCIF (Serial
-	  Communication Interface with FIFO) which are built into the Hitachi
-	  SuperH processor.  The option provides 1 to 3 (depending
-	  on the CPU model) standard Linux tty devices, /dev/ttySC[012]; one
-	  of these is normally used as the system console.
-
-	  If in doubt, press "y".
-
-config SERIAL_CONSOLE
-	bool "Support for console on serial port"
-	depends on SERIAL=y || SH_SCI=y
-	---help---
-	  If you say Y here, it will be possible to use a serial port as the
-	  system console (the system console is the device which receives all
-	  kernel messages and warnings and which allows logins in single user
-	  mode). This could be useful if some terminal or printer is connected
-	  to that serial port.
-
-	  Even if you say Y here, the currently visible virtual console
-	  (/dev/tty0) will still be used as the system console by default, but
-	  you can alter that using a kernel command line option such as
-	  "console=ttyS1". (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.)
-
-	  If you don't have a VGA card installed and you say Y here, the
-	  kernel will automatically use the first serial line, /dev/ttyS0, as
-	  system console.
-
-	  If unsure, say N.
-
-comment "Unix98 PTY support"
-
-config UNIX98_PTYS
-	bool "Unix98 PTY support"
-	---help---
-	  A pseudo terminal (PTY) is a software device consisting of two
-	  halves: a master and a slave. The slave device behaves identical to
-	  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.
-
-	  The entries in /dev/pts/ are created on the fly by a virtual
-	  file system; therefore, if you say Y here you should say Y to
-	  "/dev/pts file system for Unix98 PTYs" as well.
-
-	  If you want to say Y here, you need to have the C library glibc 2.1
-	  or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
-	  Read the instructions in <file:Documentation/Changes> pertaining to
-	  pseudo terminals. It's safe to say N.
-
-config UNIX98_PTY_COUNT
-	int "Maximum number of Unix98 PTYs in use (0-2048)"
-	depends on UNIX98_PTYS
-	default "256"
-	help
-	  The maximum number of Unix98 PTYs that can be used at any one time.
-	  The default is 256, and should be enough for desktop systems. Server
-	  machines which support incoming telnet/rlogin/ssh connections and/or
-	  serve several X terminals may want to increase this: every incoming
-	  connection and every xterm uses up one PTY.
-
-	  When not in use, each additional set of 256 PTYs occupy
-	  approximately 8 KB of kernel memory on 32-bit architectures.
-
-config HEARTBEAT
-	bool "Heartbeat LED"
-	depends on SH_MPC1211 || SH_CAT68701 || SH_STB1_HARP || SH_STB1_OVERDRIVE || SH_BIGSUR || SH_7751_SOLUTION_ENGINE || SH_SOLUTION_ENGINE

-config PRINTER
-	tristate "Parallel printer support"
-	depends on PARPORT
-	---help---
-	  If you intend to attach a printer to the parallel port of your Linux
-	  box (as opposed to using a serial printer; if the connector at the
-	  printer has 9 or 25 holes ["female"], then it's serial), say Y.
-	  Also read the Printing-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
-
-	  It is possible to share one parallel port among several devices
-	  (e.g. printer and ZIP drive) and it is safe to compile the
-	  corresponding drivers into the kernel.
-	  To compile this driver as a module, choose M here and read
-	  <file:Documentation/parport.txt>.  The module will be called lp.
-
-	  If you have several parallel ports, you can specify which ports to
-	  use with the "lp" kernel command line option.  (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.)  The syntax of the
-	  "lp" command line option can be found in <file:drivers/char/lp.c>.
-
-	  If you have more than 8 printers, you need to increase the LP_NO
-	  macro in lp.c and the PARPORT_MAX macro in parport.h.
-
-config LP_CONSOLE
-	bool "Support for console on line printer"
-	depends on PRINTER
-	---help---
-	  If you want kernel messages to be printed out as they occur, you
-	  can have a console on the printer. This option adds support for
-	  doing that; to actually get it to happen you need to pass the
-	  option "console=lp0" to the kernel at boot time.
-
-	  If the printer is out of paper (or off, or unplugged, or too
-	  busy..) the kernel will stall until the printer is ready again.
-	  By defining CONSOLE_LP_STRICT to 0 (at your own risk) you
-	  can make the kernel continue when this happens,
-	  but it'll lose the kernel messages.
-
-	  If unsure, say N.
-
-config PPDEV
-	tristate "Support for user-space parallel port device drivers"
-	depends on PARPORT
-	---help---
-	  Saying Y to this adds support for /dev/parport device nodes.  This
-	  is needed for programs that want portable access to the parallel
-	  port, for instance deviceid (which displays Plug-and-Play device
-	  IDs).
-
-	  This is the parallel port equivalent of SCSI generic support (sg).
-	  It is safe to say N to this -- it is not needed for normal printing
-	  or parallel port CD-ROM/disk support.
-
-	  To compile this support as a module, choose M here: the
-	  module will be called ppdev.
-
-	  If unsure, say N.
-
-config PSMOUSE
-	bool "PS/2 mouse (aka \"auxiliary device\") support"
-	---help---
-	  The PS/2 mouse connects to a special mouse port that looks much like
-	  the keyboard port (small circular connector with 6 pins). This way,
-	  the mouse does not use any serial ports. This port can also be used
-	  for other input devices like light pens, tablets, keypads. Compaq,
-	  AST and IBM all use this as their mouse port on currently shipping
-	  machines. The trackballs of some laptops are PS/2 mice also. In
-	  particular, the C&T 82C710 mouse on TI Travelmates is a PS/2 mouse.
-
-	  Although PS/2 mice are not technically bus mice, they are explained
-	  in detail in the Busmouse-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
-
-	  When using a PS/2 mouse, you can get problems if you want to use the
-	  mouse both on the Linux console and under X. Using the "-R" option
-	  of the Linux mouse managing program gpm (available from
-	  <ftp://gnu.systemy.it/pub/gpm/>) solves this problem, or you can get
-	  the "mconv2" utility from <ftp://ibiblio.org/pub/Linux/system/mouse/>.

-config RTC
-	tristate "Enhanced Real Time Clock Support"
-	---help---
-	  If you say Y here and create a character special file /dev/rtc with
-	  major number 10 and minor number 135 using mknod ("man mknod"), you
-	  will get access to the real time clock (or hardware clock) built
-	  into your computer.
-
-	  Every PC has such a clock built in. It can be used to generate
-	  signals from as low as 1Hz up to 8192Hz, and can also be used
-	  as a 24 hour alarm. It reports status information via the file
-	  /proc/driver/rtc and its behaviour is set by various ioctls on
-	  /dev/rtc.
-
-	  If you run Linux on a multiprocessor machine and said Y to
-	  "Symmetric Multi Processing" above, you should say Y here to read
-	  and set the RTC in an SMP compatible fashion.
-
-	  If you think you have a use for such a device (such as periodic data
-	  sampling), then say Y here, and read <file:Documentation/rtc.txt>
-	  for details.
-
-	  To compile this driver as a module, choose M here: the
-	  module will be called rtc.
