From: Lianbo Jiang <lijiang@xxxxxxxxxx> [ Upstream commit 112eee5d06007dae561f14458bde7f2a4879ef4e ] Add a forward declaration of struct kimage to the crash.h header because future changes will invoke a crash-specific function from the realmode init path and the compiler will complain otherwise like this: In file included from arch/x86/realmode/init.c:11: ./arch/x86/include/asm/crash.h:5:32: warning: ‘struct kimage’ declared inside\ parameter list will not be visible outside of this definition or declaration 5 | int crash_load_segments(struct kimage *image); | ^~~~~~ ./arch/x86/include/asm/crash.h:6:37: warning: ‘struct kimage’ declared inside\ parameter list will not be visible outside of this definition or declaration 6 | int crash_copy_backup_region(struct kimage *image); | ^~~~~~ ./arch/x86/include/asm/crash.h:7:39: warning: ‘struct kimage’ declared inside\ parameter list will not be visible outside of this definition or declaration 7 | int crash_setup_memmap_entries(struct kimage *image, | [ bp: Rewrite the commit message. ] Reported-by: kbuild test robot <lkp@xxxxxxxxx> Signed-off-by: Lianbo Jiang <lijiang@xxxxxxxxxx> Signed-off-by: Borislav Petkov <bp@xxxxxxx> Cc: bhe@xxxxxxxxxx Cc: d.hatayama@xxxxxxxxxxx Cc: dhowells@xxxxxxxxxx Cc: dyoung@xxxxxxxxxx Cc: ebiederm@xxxxxxxxxxxx Cc: horms@xxxxxxxxxxxx Cc: "H.
