CVE: CVE-2023-1249

--------------------------------

The coredump_params structure is only used as parameters for function
pointer members of some structures, such as linux_binfmt, spufs_calls,
etc., and the parameters are of pointer type, so adding members of
coredump_params will not affect the memory layout.

Also coredump_params is used to hold coredump parameters to be passed to
coredump functions of different types of binfmt, the driver will not use
the structure.
