+	  but it is independent of the system firmware.  And like a reboot
+	  you can start any kernel with it, not just Linux.
+
+	  The name comes from the similarity to the exec system call.
+
+	  It is an ongoing process to be certain the hardware in a machine
+	  is properly shutdown, so do not be surprised if this code does not
+	  initially work for you.  As of this writing the exact hardware

+	  a crash by kdump/kexec. The crash dump kernel must be compiled

+	---help---
+	  This gives the physical address where the kernel is loaded
+	  and is ordinarily the same as MEMORY_START.
+
+	  Different values are primarily used in the case of kexec on panic
+	  where the fail safe kernel needs to run at a different address

+	depends on PROC_FS
+	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 prctl, it cannot be disabled and the task is only
+	  allowed to execute a few safe syscalls defined by each seccomp
+	  mode.

+
+	  If you say N here, the kernel will run on uni- 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,
+	  uniprocessor machines. On a uniprocessor 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.
+
+	  See also <file:Documentation/lockup-watchdogs.txt> and the SMP-HOWTO
+	  available at <http://www.tldp.org/docs.html#howto>.

+ * Dreamcast System ASIC Hardware Events -
+ *
+ * The Dreamcast's System ASIC (a.k.a. Holly) is responsible for receiving
+ * hardware events from system peripherals and triggering an SH7750 IRQ.
+ * Hardware events can trigger IRQs 13, 11, or 9 depending on which bits are
+ * set in the Event Mask Registers (EMRs).  When a hardware event is
+ * triggered, its corresponding bit in the Event Status Registers (ESRs)
+ * is set, and that bit should be rewritten to the ESR to acknowledge that
+ * event.
+ *
+ * There are three 32-bit ESRs located at 0xa05f6900 - 0xa05f6908.  Event
+ * types can be found in arch/sh/include/mach-dreamcast/mach/sysasic.h.
+ * There are three groups of EMRs that parallel the ESRs.  Each EMR group
+ * corresponds to an IRQ, so 0xa05f6910 - 0xa05f6918 triggers IRQ 13,
+ * 0xa05f6920 - 0xa05f6928 triggers IRQ 11, and 0xa05f6930 - 0xa05f6938
+ * triggers IRQ 9.
+ *
+ * In the kernel, these events are mapped to virtual IRQs so that drivers can
+ * respond to them as they would a normal interrupt.  In order to keep this
+ * mapping simple, the events are mapped as:
+ *
+ * 6900/6910 - Events  0-31, IRQ 13
+ * 6904/6924 - Events 32-63, IRQ 11
+ * 6908/6938 - Events 64-95, IRQ  9

+ *
+ * - Bits 0 and 7 are reserved on SH-3 (_PAGE_WT and _PAGE_SZ1 on SH-4).
+ *
+ * - Bit 1 is the SH-bit, but is unused on SH-3 due to an MMU bug (the
+ *   hardware PTEL value can't have the SH-bit set when MMUCR.IX is set,
+ *   which is the default in cpu-sh3/mmu_context.h:MMU_CONTROL_INIT).
+ *
+ *   In order to keep this relatively clean, do not use these for defining
+ *   SH-3 specific flags until all of the other unused bits have been
+ *   exhausted.
+ *
+ * - Bit 9 is reserved by everyone and used by _PAGE_PROTNONE.
+ *
+ * - Bits 10 and 11 are low bits of the PPN that are reserved on >= 4K pages.
+ *   Bit 10 is used for _PAGE_ACCESSED, and bit 11 is used for _PAGE_SPECIAL.
+ *
+ * - On 29 bit platforms, bits 31 to 29 are used for the space attributes
+ *   and timing control which (together with bit 0) are moved into the
+ *   old-style PTEA on the parts that support it.
+ *
+ * SH-X2 MMUs and extended PTEs
+ *
+ * SH-X2 supports an extended mode TLB with split data arrays due to the
+ * number of bits needed for PR and SZ (now EPR and ESZ) encodings. The PR and
+ * SZ bit placeholders still exist in data array 1, but are implemented as
+ * reserved bits, with the real logic existing in data array 2.
+ *
+ * The downside to this is that we can no longer fit everything in to a 32-bit
+ * PTE encoding, so a 64-bit pte_t is necessary for these parts. On the plus
+ * side, this gives us quite a few spare bits to play with for future usage.

+ * that the previous frame cannot be determined, that's all we can do.

+ * 0x30-0x3f	debug traps used by the kernel.
+ * 0x40-0xff	Not supported by all parts, so left unhandled.
+ *
+ * For making system calls, any trap number in the range for the
+ * given cpu model may be used, but the unified trap number 0x1f is
+ * preferred for compatibility with all models.
+ *
+ * The low bits of the trap number were once documented as matching
+ * the number of arguments, but they were never actually used as such
+ * by the kernel. SH-2 originally used its own separate trap range
+ * because several hardware exceptions fell in the range used for the
+ * SH-3/4 syscall ABI.
+ *
+ * This code also handles delegating other traps to the BIOS/gdb stub.
+ *
+ * Note: When we're first called, the TRA value must be shifted
+ * right 2 bits in order to get the value that was used as the "trapa"
+ * argument.

+   Tight version of mempy for the case of just copying a page.
+   Prefetch strategy empirically optimised against RTL simulations
+   of SH5-101 cut2 eval chip with Cayman board DDR memory.
+
+   Parameters:
+   r2 : destination effective address (start of page)
+   r3 : source effective address (start of page)
+
+   Always copies 4096 bytes.
+
+   Points to review.
+   * Currently the prefetch is 4 lines ahead and the alloco is 2 lines ahead.
+     It seems like the prefetch needs to be at at least 4 lines ahead to get
+     the data into the cache in time, and the allocos contend with outstanding
+     prefetches for the same cache set, so it's better to have the numbers

+! Fast SH memcpy
+!
+! by Toshiyasu Morita (tm@netcom.com)
+! hacked by J"orn Rernnecke (joern.rennecke@superh.com) ("o for o-umlaut)
+! SH5 code Copyright 2002 SuperH Ltd.
+!
+! Entry: ARG0: destination pointer
+!        ARG1: source pointer
+!        ARG2: byte count
+!
+! Exit:  RESULT: destination pointer
+!        any other registers in the range r0-r7: trashed
+!
+! Notes: Usually one wants to do small reads and write a longword, but
+!        unfortunately it is difficult in some cases to concatanate bytes
+!        into a longword on the SH, so this does a longword read and small
+!        writes.
+!
+! This implementation makes two assumptions about how it is called:
+!
+! 1.: If the byte count is nonzero, the address of the last byte to be
+!     copied is unsigned greater than the address of the first byte to
+!     be copied.  This could be easily swapped for a signed comparison,
+!     but the algorithm used needs some comparison.
+!
+! 2.: When there are two or three bytes in the last word of an 11-or-more
+!     bytes memory chunk to b copied, the rest of the word can be read
+!     without side effects.
+!     This could be easily changed by increasing the minimum size of
+!     a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2,
+!     however, this would cost a few extra cyles on average.
+!     For SHmedia, the assumption is that any quadword can be read in its
+!     enirety if at least one byte is included in the copy.
+
+/* Imported into Linux kernel by Richard Curnow.  This is used to implement the
+   __copy_user function in the general case, so it has to be a distinct
+   function from intra-kernel memcpy to allow for exception fix-ups in the
+   event that the user pointer is bad somewhere in the copy (e.g. due to
+   running off the end of the vma).
+
+   Note, this algorithm will be slightly wasteful in the case where the source
+   and destination pointers are equally aligned, because the stlo/sthi pairs
+   could then be merged back into single stores.  If there are a lot of cache
+   misses, this is probably offset by the stall lengths on the preloads.
+
+*/
+
+/* NOTE : Prefetches removed and allocos guarded by synco to avoid TAKum03020
+ * erratum.  The first two prefetches are nop-ed out to avoid upsetting the
+ * instruction counts used in the jump address calculation.

+	  boot on these systems, this option must not be set.
+
+	  On other systems (such as the SH-3 and 4) where an MMU exists,

+	help
+	  The kernel memory allocator divides physically contiguous memory
+	  blocks into "zones", where each zone is a power of two number of
+	  pages.  This option selects the largest power of two that the kernel
+	  keeps in the memory allocator.  If you need to allocate very large
+	  blocks of physically contiguous memory, then you may need to
+	  increase this value.
+
+	  This config option is actually maximum order plus one. For example,
+	  a value of 11 means that the largest free memory block is 2^10 pages.
+
+	  The page size is not necessarily 4KB. Keep this in mind when

+	  does not specify the range that RAM takes.
+

+	  boards typically map RAM at 0C000000.
+
