Therefore, this patch protects some portion of kprobe code and renames few other, so that decode-insn functionality can be reused by uprobe even when CONFIG_KPROBES is not defined. kprobe_opcode_t and struct arch_specific_insn are also defined by linux/kprobes.h, when CONFIG_KPROBES is not defined. So, protect these definitions in asm/probes.h. linux/kprobes.h already includes asm/kprobes.h. Therefore, remove inclusion of asm/kprobes.h from decode-insn.c. There are some definitions like kprobe_insn and kprobes_handler_t etc can be re-used by uprobe. So, it would be better to remove 'k' from their names. struct arch_specific_insn is specific to kprobe. Therefore, introduce a new struct arch_probe_insn which will be common for both kprobe and uprobe, so that decode-insn code can be shared. Modify kprobe code accordingly. Function arm_probe_decode_insn() will be needed by uprobe as well. So make it global.
