-         in /dev. Devfs does not depend on major and minor number
-         allocations. Device drivers register entries in /dev which then
-         appear automatically, which means that the system administrator does
-         not have to create character and block special device files in the
-         /dev directory using the mknod command (or MAKEDEV script) anymore.
-
-         This is work in progress. If you want to use this, you *must* read
-         the material in <file:Documentation/filesystems/devfs/>, especially
-         the file README there.
-
-         Note that devfs no longer manages /dev/pts!  If you are using UNIX98
-         ptys, you will also need to mount the /dev/pts filesystem (devpts).

+         Advanced Configuration and Power Interface (ACPI) support for 
+         Linux requires an ACPI compliant platform (hardware/firmware),
+         and assumes the presence of OS-directed configuration and power
+         management (OSPM) software.  This option will enlarge your 
+         kernel by about 70K.
+
+         Linux ACPI provides a robust functional replacement for several 
+         legacy configuration and power management interfaces, including
+         the Plug-and-Play BIOS specification (PnP BIOS), the 
+         MultiProcessor Specification (MPS), and the Advanced Power 
+         Management (APM) specification.  If both ACPI and APM support 
+         are configured, whichever is loaded first shall be used.
+
+         The ACPI SourceForge project contains the latest source code, 
+         documentation, tools, mailing list subscription, and other 
+         information.  This project is available at:
+         <http://sourceforge.net/projects/acpi>
+
+         Linux support for ACPI is based on Intel Corporation's ACPI
+         Component Architecture (ACPI CA).  For more information see:
+         <http://developer.intel.com/technology/iapc/acpi>
+
+         ACPI is an open industry specification co-developed by Compaq, 
+         Intel, Microsoft, Phoenix, and Toshiba.  The specification is 
+         available at:
+         <http://www.acpi.info>

+
+         With this option, you will be able to put the system "to sleep". 
+         Sleep states are low power states for the system and devices. All
+         of the system operating state is saved to either memory or disk
+         (depending on the state), to allow the system to resume operation
+         quickly at your request.
+
+         Although this option sounds really nifty, barely any of the device
+         drivers have been converted to the new driver model and hence few

+          support some Medion laptops (such as 9675 for example).  It makes all
+          the extra buttons generate standard ACPI events that go through
+          /proc/acpi/events, and (on some models) adds support for changing the
+          display brightness and output, switching the LCD backlight on and 
off,
+          and most importantly, allows you to blink those fancy LEDs intended
+          for reporting mail and wireless status.
+
+         Note: display switching code is currently considered EXPERIMENTAL,
+         toying with these values may even lock your machine.
+          
+          All settings are changed via /proc/acpi/asus directory entries. Owner

+
+         This driver differs from the non-ACPI Toshiba laptop driver (located
+         under "Processor type and features") in several aspects.
+         Configuration is accessed by reading and writing text files in the
+         /proc tree instead of by program interface to /dev.  Furthermore, no
+         power management functions are exposed, as those are handled by the
+         general ACPI drivers.
+

+       help
+         This is the traditional Linux preemption model, geared towards
+         throughput. It will still provide good latencies most of the
+         time, but there are no guarantees and occasional longer delays
+         are possible.
+
+         Select this option if you are building a kernel for a server or
+         scientific/computation system, or if you want to maximize the
+         raw processing power of the kernel, irrespective of scheduling
+         latencies.

+       bool "Voluntary Kernel Preemption (Desktop)"
+       help
+         This option reduces the latency of the kernel by adding more
+         "explicit preemption points" to the kernel code. These new
+         preemption points have been selected to reduce the maximum
+         latency of rescheduling, providing faster application reactions,
+         at the cost of slighly lower throughput.
+
+         This allows reaction to interactive events by allowing a
+         low priority process to voluntarily preempt itself even if it
+         is in kernel mode executing a system call. This allows
+         applications to run more 'smoothly' even when the system is
+         under load.

+         permitting a low priority process to be preempted involuntarily
+         even if it is in kernel mode executing a system call and would
+         otherwise not be about to reach a natural preemption point.
+         This allows applications to run more 'smoothly' even when the
+         system is under load, at the cost of slighly lower throughput
+         and a slight runtime overhead to kernel code.

- *  Handle resources of PCI devices.  If the world were perfect, we could
- *  just allocate all the resource regions and do nothing more.  It isn't.
- *  On the other hand, we cannot just re-allocate all devices, as it would
- *  require us to know lots of host bridge internals.  So we attempt to
- *  keep as much of the original configuration as possible, but tweak it
- *  when it's found to be wrong.
- *
- *  Known BIOS problems we have to work around:
- *     - I/O or memory regions not configured
- *     - regions configured, but not enabled in the command register
- *     - bogus I/O addresses above 64K used
- *     - expansion ROMs left enabled (this may sound harmless, but given
- *       the fact the PCI specs explicitly allow address decoders to be
- *       shared between expansion ROMs and other resource regions, it's
- *       at least dangerous)
- *
- *  Our solution:
- *     (1) Allocate resources for all buses behind PCI-to-PCI bridges.
- *         This gives us fixed barriers on where we can allocate.
- *     (2) Allocate resources for all enabled devices.  If there is
- *         a collision, just mark the resource as unallocated. Also
- *         disable expansion ROMs during this step.
- *     (3) Try to allocate resources for disabled devices.  If the
- *         resources were assigned correctly, everything goes well,
- *         if they weren't, they won't disturb allocation of other
- *         resources.
- *     (4) Assign new addresses to resources which were either
- *         not configured at all or misconfigured.  If explicitly
- *         requested by the user, configure expansion ROM address
- *         as well.

- * initialized data (doesn't apply to uninitialized data)
- * as `initialization' functions. The kernel can take this
- * as hint that the function is used only during the initialization
- * phase and free up used memory resources after
- *
- * Usage:
- * For functions:
- * 
- * You should add __init immediately before the function name, like:
- *
- * static void __init initme(int x, int y)
- * {
- *    extern int z; z = x * y;
- * }
- *
- * If the function has a prototype somewhere, you can also add
- * __init between closing brace of the prototype and semicolon:
- *
- * extern int initialize_foobar_device(int, int, int) __init;
- *
- * For initialized data:
- * You should insert __initdata between the variable name and equal
- * sign followed by value, e.g.:
- *
- * static int init_variable __initdata = 0;
- * static char linux_logo[] __initdata = { 0x32, 0x36, ... };
- *
- * Don't forget to initialize data not at file scope, i.e. within a function,
- * as gcc otherwise puts the data into the bss section and not into the init
- * section.
- * 
- * Also note, that this data cannot be "const".
