	* config/s390/nm-linux.h: Update comments.
	(target_insert_watchpoint, target_remove_watchpoint): Redefine.
	(STOPPED_BY_WATCHPOINT): Redefine.
	(TARGET_CAN_USE_HARDWARE_WATCHPOINT): Redefine to 1.
	(s390_insert_watchpoint, s390_remove_watchpoint): Update prototype.
	(s390_stopped_by_watchpoint): Likewise.
	(watch_area_cnt): Remove.
	* s390-nat.c: Update comments.
	(watch_area): Remove typedef.
	Global replace watch_area by struct watch_area.
	(watch_area_cnt, watch_lo_addr, watch_hi_addr): Remove.
	(s390_stopped_by_watchpoint): Remove pid argument,
	use s390_inferior_tid.  Add short-cut for the no watchpoint case.
	(s390_fix_watch_points): Remove pid argument,
	use s390_inferior_tid.  Recompute area spanned by watchpoints.
	(s390_insert_watchpoint, s390_remove_watchpoint): Remove pid
	argument.  Reimplement.
