+ * We do not have hardware single-stepping on ARM, This
+ * effort is further complicated by the ARM not having a
+ * "next PC" register. Instructions that change the PC
+ * can't be safely single-stepped in a MP environment, so
+ * we have a lot of work to do:
+ *
+ * In the prepare phase:
+ * *) If it is an instruction that does anything
+ * with the CPU mode, we reject it for a kprobe.
+ * (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.

+ * To avoid the complications of mimicing single-stepping on a
+ * processor without a Next-PC or a single-step mode, and to
+ * avoid having to deal with the side-effects of boosting, we
+ * simulate or emulate (almost) all ARM instructions.
+ *
+ * "Simulation" is where the instruction's behavior is duplicated in
+ * C code. "Emulation" is where the original instruction is rewritten
+ * and executed, often by altering its registers.
+ *
+ * By having all behavior of the kprobe'd instruction completed before
+ * returning from the kprobe_handler(), all locks (scheduler and
+ * interrupt) can safely be released. There is no need for secondary
+ * breakpoints, no race with MP or preemptable kernels, nor having to
+ * clean up resources counts at a later time impacting overall system
+ * performance. By rewriting the instruction, only the minimum registers
+ * need to be loaded and saved back optimizing performance.
+ *
+ * Calling the insnslot_*_rwflags version of a function doesn't hurt
+ * anything even when the CPSR flags aren't updated by the
+ * instruction. It's just a little slower in return for saving
+ * a little space by not having a duplicate function that doesn't
+ * update the flags. (The same optimization can be said for
+ * instructions that do or don't perform register writeback)
+ * Also, instructions can either read the flags, only write the
+ * flags, or read and write the flags. To save combinations
+ * rather than for sheer performance, flag functions just assume
+ * read and write of flags.
