* frame.h: Note that namelen can be negative.
	* frame.c (frame_map_name_to_regnum): When LEN is negative, use
	NAME's length.

	* NEWS: Mention that the d10v's `regs' command is deprecated.
	* d10v-tdep.c (d10v_gdbarch_init): Set print_registers_info.
	(d10v_print_registers_info): New function.
	(show_regs): Call d10v_print_registers_info.
	(_initialize_d10v_tdep): Mark "show regs" command as deprecated.
