On m68k, which does not define CORE_DUMP_USE_REGSET:

    fs/binfmt_elf.c: In function ‘fill_note_info’:
    fs/binfmt_elf.c:2040:20: error: passing argument 1 of ‘fill_prstatus’ from incompatible pointer type [-Werror=incompatible-pointer-types]
     2040 |  fill_prstatus(info->prstatus, current, siginfo->si_signo);
	  |                ~~~~^~~~~~~~~~
	  |                    |
	  |                    struct elf_prstatus *
    fs/binfmt_elf.c:1498:55: note: expected ‘struct elf_prstatus_common *’ but argument is of type ‘struct elf_prstatus *’
     1498 | static void fill_prstatus(struct elf_prstatus_common *prstatus,
	  |                           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~

The fill_prstatus() signature was changed, but one caller was not
updated.
