+	  The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
+	  You can operate a Linux system on this board by using an M32R
+	  softmacro core, which is a fully-synthesizable functional model
+	  described in Verilog-HDL.
+
+	  The Mappi-I board was the first platform, which had been used
+	  to port and develop a Linux system for the M32R processor.

+	  This allows applications to run more reliably even when the system is

+	  This enables support for systems with more than one CPU. If you have

+	  you have a system with more than one CPU, say Y.
+
+	  If you say N here, the kernel will run on single and multiprocessor
+	  machines, but will use only one CPU of a multiprocessor machine. If
+	  you say Y here, the kernel will run on many, but not all,
+	  singleprocessor machines. On a singleprocessor machine, the kernel
+	  will run faster if you say N here.
+
+	  People using multiprocessor machines who say Y here should also say
+	  Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
+	  Management" code will be disabled if you say Y here.
+
+	  See also the SMP-HOWTO available at
+	  <http://tldp.org/HOWTO/SMP-HOWTO.html>.

+	  On PCI systems, the BIOS can be used to detect the PCI devices and
+	  determine their configuration. However, some old PCI motherboards
+	  have BIOS bugs and may crash if this is done. Also, some embedded
+	  PCI-based systems don't have any BIOS at all. Linux can also try to
+	  detect the PCI hardware directly without using the BIOS.
+
+	  With this option, you can specify how Linux should detect the PCI
+	  devices. If you choose "BIOS", the BIOS will be used, if you choose
+	  "Direct", the BIOS won't be used, and if you choose "Any", the
+	  kernel will try the direct access method and falls back to the BIOS
+	  if that doesn't work. If unsure, go with the default, which is

+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *      CPU 0                           CPU 1
+ *
+ *      b = 2;
+ *      memory_barrier();
+ *      p = &b;                         q = p;
+ *                                      read_barrier_depends();
+ *                                      d = *q;
+ * </programlisting>
+ *
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends().  However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ *      CPU 0                           CPU 1
+ *
+ *      a = 2;
+ *      memory_barrier();
+ *      b = 3;                          y = b;
+ *                                      read_barrier_depends();
+ *                                      x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b".  Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
+ * in cases like this where there are no data dependencies.

+ * The actual file contents are as follows:
+ * UPAGE: 1 page consisting of a user struct that tells gdb
+ *	what is present in the file.  Directly after this is a
+ *	copy of the task_struct, which is currently not used by gdb,
+ *	but it may come in handy at some point.  All of the registers
+ *	are stored as part of the upage.  The upage should always be
+ *	only one page.
+ * DATA: The data area is stored.  We use current->end_text to
+ *	current->brk to pick up all of the user variables, plus any memory
+ *	that may have been sbrk'ed.  No attempt is made to determine if a
+ *	page is demand-zero or if a page is totally unused, we just cover
+ *	the entire range.  All of the addresses are rounded in such a way
+ *	that an integral number of pages is written.
+ * STACK: We need the stack information in order to get a meaningful
+ *	backtrace.  We need to write the data from usp to
+ *	current->start_stack, so we round each of these off in order to be
+ *	able to write an integer number of pages.
