[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 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.

+ string "Default main console channel initialization"
+ default "fd:0,fd:1"
+ 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.

+ 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

+ 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"
+ default "pty"
+ 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_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.
