	gdb/
	* remote.c (remote_check_symbols): Use
	gdbarch_convert_from_func_ptr_addr.
	* infcall.c (find_function_addr): Handle function descriptors
	without debugging information.
	* ppc-linux-tdep.c (ppc_linux_convert_from_func_ptr_addr): Renamed
	from ppc64_linux_convert_from_func_ptr_addr.  Handle -msecure-plt.
	(ppc_linux_init_abi): Always set convert_from_func_ptr_addr.
	* solib-svr4.c (solib_break_names): Remove "._dl_debug_state".
	(bfd_lookup_symbol): Do not take a SECT_FLAGS argument.  Always
	allow SEC_CODE and SEC_DATA.
	(enable_break): Update calls.  Pass current_target to solib_add.
	Use gdbarch_convert_from_func_ptr_addr.

	gdb/gdbserver/
	* remote-utils.c (look_up_one_symbol): Handle 'm' packets.
