The probe_opcode_t typedef for u32 isn't necessary, and is a source of confusion as it is easily confused with kprobe_opcode_t, which is a typedef for __le32. The typedef is only used within arch/arm64, and all of arm64's commn insn code uses u32 for the endian-agnostic value of an instruction, so it'd be clearer to use u32 consistently. Remove probe_opcode_t and use u32 directly. There should be no functional change as a result of this patch.
