+ *
+ * In other cases, such as the interrupt/exception path, we can poke around
+ * the sp/fp.
+ *
+ * Notably, this entire approach is somewhat error prone, and in the event
+ * that the previous frame cannot be determined, that's all we can do.
+ * Either way, this still leaves us with a more correct backtrace then what

+!
+! 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 minumum 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.
