+ *      (This is out of laziness rather than need.  The
+ *      instructions could be simulated.)
+ *
+ *   *) Otherwise, decode the instruction rewriting its
+ *      registers to take fixed, ordered registers and
+ *      setting a handler for it to run the instruction.
+ *
+ * In the execution phase by an instruction's handler:
+ *
+ *   *) If the PC is written to by the instruction, the
+ *      instruction must be fully simulated in software.
+ *      If it is a conditional instruction, the handler
+ *      will use insn[0] to copy its condition code to
+ *      set r0 to 1 and insn[1] to "mov pc, lr" to return.
+ *
+ *   *) Otherwise, a modified form of the instruction is
+ *      directly executed.  Its handler calls the
+ *      instruction in insn[0].  In insn[1] is a
+ *      "mov pc, lr" to return.
+ *
+ *      Before calling, load up the reordered registers
+ *      from the original instruction's registers.  If one
+ *      of the original input registers is the PC, compute
+ *      and adjust the appropriate input register.
+ *
+ *      After call completes, copy the output registers to
+ *      the original instruction's original registers.
+ *
+ * We don't use a real breakpoint instruction since that
+ * would have us in the kernel go from SVC mode to SVC
+ * mode losing the link register.  Instead we use an
+ * undefined instruction.  To simplify processing, the
+ * undefined instruction used for kprobes must be reserved
+ * exclusively for kprobes use.

+ * performance.  By rewriting the instruction, only the minimum registers
+ * need to be loaded and saved back optimizing performance.

+ * update the flags.  (The same optimization can be said for

+ * { SFN => IN }  Change CON first
+ * { SFN => OUT } Change DAT first, so new data will not glitch [1]

-          algorithm.
-          Rijndael appears to be consistently a very good performer in
-          both hardware and software across a wide range of computing
-          environments regardless of its use in feedback or non-feedback
-          modes. Its key setup time is excellent, and its key agility is
-          good. Rijndael's very low memory requirements make it very well
-          suited for restricted-space environments, in which it also
-          demonstrates excellent performance. Rijndael's operations are
-          among the easiest to defend against power and timing attacks.
