-         The BBC devices on the UltraSPARC III have two I2C controllers.  The
-         first I2C controller connects mainly to configuration PROMs (NVRAM,
-         CPU configuration, DIMM types, etc.).  The second I2C controller
-         connects to environmental control devices such as fans and

-         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 :-)

-         would use the third virtual terminal as system console. (Try "man

+       help
+         This kernel feature is useful for number crunching applications
+         that may need to compute untrusted bytecode during their
+         execution. By using pipes or other transports made available to
+         the process as file descriptors supporting the read/write
+         syscalls, it's possible to isolate those applications in
+         their own address space using seccomp. Once seccomp is
+         enabled via /proc/<pid>/seccomp, it cannot be disabled
+         and the task is only allowed to execute a few safe syscalls
+         defined by each seccomp mode.

-         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.

-         introduced in XFree86 4.0. If you say Y here, you need to select
-         the module that's right for your graphics card from the list below.
-         These modules provide support for synchronization, security, and
-         DMA transfers. Please see <http://dri.sourceforge.net/> for more
-         details.  You should also select and configure AGP
-         (/dev/agpgart) support.

-config DRM_FFB
-       tristate "Creator/Creator3D"
-       depends on DRM && BROKEN
-       help
-         Choose this option if you have one of Sun's Creator3D-based graphics
-         and frame buffer cards.  Product page at
-         <http://www.sun.com/desktop/products/Graphics/creator3d.html>.

-config DRM_TDFX
-       tristate "3dfx Banshee/Voodoo3+"
-       depends on DRM
-       help
-         Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
-         graphics card.  If M is selected, the module will be called tdfx.

        help

-         Choose this option if you have an ATI Rage 128 graphics card.  If M
-         is selected, the module will be called r128.  AGP support for
-         this card is strongly suggested (unless you have a PCI version).

+         Kprobes allows you to trap at almost any kernel address and
+         execute a callback function.  register_kprobe() establishes
+         a probepoint and specifies the callback.  Kprobes is useful
+         for kernel debugging, non-intrusive instrumentation and testing.
+         If in doubt, say "N".
