Yes, it looks like they will currently be used for core regsets on
SPARC. They shouldn't be; the Linux port could use an update to the
new regset mechanism, used by e.g. the BSDs. That could add
cross-debug support for core files also.
They are also used for thread debugging, but that's general
GDB-for-Linux lameness; that part of linux-thread-db.c needs to be
eliminated. It's on the todo list.

Thanks. But, in the future, could you please wait for your patches to
be reviewed like everyone else (or ask to be the maintainer for this
port)?
You added includes to source files, so Makefile.in needs to be updated.
