+       * NEWS: Mention "maint set/show target-non-stop".
+       * breakpoint.c (update_global_location_list): Check
+       target_is_non_stop_p instead of non_stop.
+       * infcmd.c (attach_command_post_wait, attach_command): Likewise.
+       * infrun.c (show_can_use_displaced_stepping)
+       (can_use_displaced_stepping_p, start_step_over_inferior):
+       Likewise.
+       (internal_resume_ptid): New function.
+       (resume): Use it.
+       (proceed): Check target_is_non_stop_p instead of non_stop.  If in
+       all-stop mode but the target is always in non-stop mode, start all
+       the other threads that are implicitly resumed too.
+       (for_each_just_stopped_thread, fetch_inferior_event)
+       (adjust_pc_after_break, stop_all_threads): Check
+       target_is_non_stop_p instead of non_stop.
+       (handle_inferior_event): Likewise.  Handle detach-fork in all-stop
+       with the target always in non-stop mode.
+       (handle_signal_stop) <random signal>: Check target_is_non_stop_p
+       instead of non_stop.
+       (switch_back_to_stepped_thread): Check target_is_non_stop_p
+       instead of non_stop.
+       (keep_going_stepped_thread): Use internal_resume_ptid.
+       (stop_waiting): If in all-stop mode, and the target is in non-stop
+       mode, stop all threads.
+       (keep_going_pass): Likewise, when starting a new in-line step-over
+       sequence.
+       * linux-nat.c (get_pending_status, select_event_lwp)
+       (linux_nat_filter_event, linux_nat_wait_1, linux_nat_wait): Check
+       target_is_non_stop_p instead of non_stop.
+       (linux_nat_always_non_stop_p): New function.
+       (linux_nat_stop): Check target_is_non_stop_p instead of non_stop.
+       (linux_nat_add_target): Install linux_nat_always_non_stop_p.
+       * target-delegates.c: Regenerate.
+       * target.c (target_is_non_stop_p): New function.
+       (target_non_stop_enabled, target_non_stop_enabled_1): New globals.
+       (maint_set_target_non_stop_command)
+       (maint_show_target_non_stop_command): New functions.
+       (_initilize_target): Install "maint set/show target-non-stop"
+       commands.
+       * target.h (struct target_ops) <to_always_non_stop_p>: New field.
+       (target_non_stop_enabled): New declaration.
+       (target_is_non_stop_p): New declaration.
