        * hppa-tdep.h (enum hppa_regnum): Add members for all space registers.
        * hppaobsd-tdep.c (HPPAOBSD_SIZEOF_GREGS): Add comment.
        (HPPANBSD_SIZEOF_GREGS): New define.
        (hppaobsd_supply_gregset): Handle additional registers.
        * hppabsd-nat.c (hppabsd_gregset_supplies_p): Adjust to indicate
        we provide more registers now.
        (hppabsd_supply_gregset): Supply additional registers.
        (hppabsd_collect_gregset): Collect additional registers.
