[ Upstream commit 0f74914071ab7e7b78731ed62bf350e3a344e0a5 ]
When building with W=1, gcc properly complains that there's no prototypes:
CC kernel/elfcore.o kernel/elfcore.c:7:17: warning: no previous prototype for 'elf_core_extra_phdrs' [-Wmissing-prototypes] 7 | Elf_Half __weak elf_core_extra_phdrs(void) | ^~~~~~~~~~~~~~~~~~~~ kernel/elfcore.c:12:12: warning: no previous prototype for 'elf_core_write_extra_phdrs' [-Wmissing-prototypes] 12 | int __weak elf_core_write_extra_phdrs(struct coredump_params *cprm, loff_t offset) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ kernel/elfcore.c:17:12: warning: no previous prototype for 'elf_core_write_extra_data' [-Wmissing-prototypes] 17 | int __weak elf_core_write_extra_data(struct coredump_params *cprm) | ^~~~~~~~~~~~~~~~~~~~~~~~~ kernel/elfcore.c:22:15: warning: no previous prototype for 'elf_core_extra_data_size' [-Wmissing-prototypes] 22 | size_t __weak elf_core_extra_data_size(void) | ^~~~~~~~~~~~~~~~~~~~~~~~
Provide the include file so gcc is happy, and we don't have potential code drift
