+ * server.c (process_serial_event): Re-return unsupported, not
+ error, if the type isn't recognized. Re-allow supporting only
+ insert or remove packets. Also call require_running for
+ breakpoints. Add missing break statement to default case. Tidy.
+ * target.h (struct target_ops): Rename insert_watchpoint to
+ insert_point, and remove_watchpoint to remove_point.
+
+ * linux-low.h (struct linux_target_ops): Likewise.
+ * linux-low.c (linux_insert_watchpoint): Rename to ...
+ (linux_insert_point): ... this. Adjust.
+ (linux_remove_watchpoint): Rename to ...
+ (linux_remove_point): ... this. Adjust.
+ (linux_target_ops): Adjust.
+ * linux-crisv32-low.c (cris_insert_watchpoint): Rename to ...
+ (cris_insert_point): ... this.
+ (cris_remove_watchpoint): Rename to ...
+ (cris_remove_point): ... this.
+ (the_low_target): Adjust.
