[PATCH] uml: Rename Kconfig files to be like the other arches

To the extent that sub-Kconfig files exist elsewhere in the tree, they are
named Kconfig.foo, rather than the Kconfig_foo that UML has.  This patch
brings the names in line with the rest of the tree.

+config STDERR_CONSOLE

+	default y
+
+config SSL
+	bool "Virtual serial line"
+	help
+        The User-Mode Linux environment allows you to create virtual serial
+        lines on the UML that are usually made to show up on the host as
+        ttys or ptys.
+
+        See <http://user-mode-linux.sourceforge.net/input.html> for more
+        information and command line examples of how to use this facility.
+
+        Unless you have a specific reason for disabling this, say Y.
+
+config NULL_CHAN
+	bool "null channel support"
+	help
+        This option enables support for attaching UML consoles and serial
+        lines to a device similar to /dev/null.  Data written to it disappears
+        and there is never any data to be read.
+
+config PORT_CHAN
+	bool "port channel support"
+	help
+        This option enables support for attaching UML consoles and serial
+        lines to host portals.  They may be accessed with 'telnet <host>
+        <port number>'.  Any number of consoles and serial lines may be
+        attached to a single portal, although what UML device you get when
+        you telnet to that portal will be unpredictable.
+        It is safe to say 'Y' here.
+
+config PTY_CHAN
+	bool "pty channel support"
+	help
+        This option enables support for attaching UML consoles and serial
+        lines to host pseudo-terminals.  Access to both traditional
+        pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled
+        with this option.  The assignment of UML devices to host devices
+        will be announced in the kernel message log.
+        It is safe to say 'Y' here.
+
+config TTY_CHAN
+	bool "tty channel support"
+	help
+        This option enables support for attaching UML consoles and serial
+        lines to host terminals.  Access to both virtual consoles
+        (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and
+        /dev/pts/*) are controlled by this option.
+        It is safe to say 'Y' here.
+
+config XTERM_CHAN
+	bool "xterm channel support"
+	help
+        This option enables support for attaching UML consoles and serial
+        lines to xterms.  Each UML device so assigned will be brought up in
+        its own xterm.
+        If you disable this option, then CONFIG_PT_PROXY will be disabled as
+        well, since UML's gdb currently requires an xterm.
+        It is safe to say 'Y' here.

+	help
+        This is the string describing the channel to which the main console
+        will be attached by default.  This value can be overridden from the
+        command line.  The default value is "fd:0,fd:1", which attaches the
+        main console to stdin and stdout.
+        It is safe to leave this unchanged.
+
+config CON_CHAN
+	string "Default console channel initialization"
+	default "xterm"
+	help
+        This is the string describing the channel to which all consoles
+        except the main console will be attached by default.  This value can
+        be overridden from the command line.  The default value is "xterm",
+        which brings them up in xterms.
+        It is safe to leave this unchanged, although you may wish to change
+        this if you expect the UML that you build to be run in environments
+        which don't have X or xterm available.
+
+config SSL_CHAN
+	string "Default serial line channel initialization"

+	help
+        This is the string describing the channel to which the serial lines
+        will be attached by default.  This value can be overridden from the
+        command line.  The default value is "pty", which attaches them to
+        traditional pseudo-terminals.
+        It is safe to leave this unchanged, although you may wish to change
+        this if you expect the UML that you build to be run in environments
+        which don't have a set of /dev/pty* devices.
+
+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.
+
+	  All modern Linux systems use the Unix98 ptys.  Say Y unless
+	  you're on an embedded system and want to conserve memory.
+
+config LEGACY_PTYS
+	bool "Legacy (BSD) PTY support"
+	default y
+	---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, including
+	  security.  This option enables these legacy devices; on most
+	  systems, it is safe to say N.
+
+
+config LEGACY_PTY_COUNT
+	int "Maximum number of legacy PTY in use"
+	depends on LEGACY_PTYS
+	default "256"
+	---help---
+	  The maximum number of legacy PTYs that can be used at any one time.
+	  The default is 256, and should be more than enough.  Embedded
+	  systems may want to reduce this to save memory.
+
+	  When not in use, each legacy PTY occupies 12 bytes on 32-bit
+	  architectures and 24 bytes on 64-bit architectures.

+config UML_SOUND
+	tristate "Sound support"
+	help
+        This option enables UML sound support.  If enabled, it will pull in
+        soundcore and the UML hostaudio relay, which acts as a intermediary
+        between the host's dsp and mixer devices and the UML sound system.
+        It is safe to say 'Y' here.

+
+config UML_RANDOM
+	tristate "Hardware random number generator"
+	help
+	This option enables UML's "hardware" random number generator.  It
+	attaches itself to the host's /dev/random, supplying as much entropy
+	as the host has, rather than the small amount the UML gets from its
+	own drivers.  It registers itself as a standard hardware random number
+	generator, major 10, minor 183, and the canonical device name is
+	/dev/hwrng.
+	The way to make use of this is to install the rng-tools package
+	(check your distro, or download from
+	http://sourceforge.net/projects/gkernel/).  rngd periodically reads
+	/dev/hwrng and injects the entropy into /dev/random.
+
+config MMAPPER
+	tristate "iomem emulation driver"
+	help
+	This driver allows a host file to be used as emulated IO memory inside
+	UML.
