- * Unaligned accesses on uClinux can't be performed in a fault handler - the
- * CPU detects them as imprecise exceptions making this impossible.
- *
- * With the FR451, however, they are precise, and so we used to fix them up in
- * the memory access fault handler.  However, instruction bundling make this
- * impractical.  So, now we fall back to using memcpy.
