Committed by Jim Blandy <jimb@redhat.com>.
* 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.
