In the context of a patch series that makes more use of the regset
structure's 'descr' field it was suggested to rename that field to
something more meaningful (like 'regmap'), and to adjust the comment
appropriately.
(See: https://sourceware.org/ml/gdb-patches/2014-05/msg00664.html)
gdb/
* regset.h (struct regset): Rename 'descr' field to 'regmap'.
* ppc-linux-tdep.c (ppc_linux_supply_gregset)
(ppc_linux_collect_gregset ): Likewise.
* rs6000-tdep.c (ppc_supply_gregset, ppc_supply_fpregset)
(ppc_supply_vrregset, ppc_collect_gregset, ppc_collect_fpregset)
(ppc_collect_vrregset): Likewise.
* s390-linux-tdep.c (s390_supply_regset, s390_collect_regset):
Likewise.
