	* infcmd.c (stop_signal): Delete.
	(program_info): Adjust.
	* infrun.c (resume): Clear stop_signal.

	(linux_nat_corefile_thread_callback): Pass stop_signal.
	(linux_nat_do_registers): Delete.
	(linux_nat_make_corefile_notes): Use find_stop_signal.  Assume
	there's always a thread.

	* procfs.c (find_signalled_thread, find_stop_signal): New.
	(find_stop_signal): New.
	(procfs_do_thread_registers): Add stop_signal parameter.
	(struct procfs_corefile_thread_data): Add stop_signal member.
