* hppa-linux-tdep.c (greg_map): Rename to...
(hppa_linux_gregmap): ... this. Also convert to
regcache_map_entry format.
(hppa_linux_supply_regset): Delete function.
(hppa_linux_supply_fpregset): Delete function. Move logic to...
(hppa_linux_fpregmap): ... this new register map.
(hppa_linux_regset, hppa_linux_fpregset): Refer to appropriate
register map, replace supply method by regcache_supply_regset, and
add collect method regcache_collect_regset.
