+/* Core file format: The core file is written in such a way that gdb
+ * can understand it and provide useful information to the user (under
+ * linux we use the 'trad-core' bfd). There are quite a number of
+ * obstacles to being able to view the contents of the floating point
+ * registers, and until these are solved you will not be able to view
+ * the contents of them. Actually, you can read in the core file and
+ * look at the contents of the user struct to find out what the
+ * floating point registers contain.
+ *
+ * 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 useful 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 malloced. 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 (esp) to
+ * current->start_stack, so we round each of these off in order to
+ * be able to write an integer number of pages. The minimum core
+ * file size is 3 pages, or 12288 bytes.

+ * 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.

+ * NO_MMU kernel use the same r0_ram pointed space - look to vmlinux.lds.S

+ * Currently you can see register value in memory in specific place.
+ * In compare to with previous solution the speed should be the same.
+ *
+ * MMU exception handler has different handling compare to no MMU kernel.
+ * Exception handler use jump table for directing of what happen. For MMU kernel
+ * is this approach better because MMU relate exception are handled by asm code
+ * in this file. In compare to with MMU expect of unaligned exception
