jump_label: Fix sparc64 warning
The kbuild test robot reported the following warning on sparc64: kernel/jump_label.c: In function '__jump_label_update': kernel/jump_label.c:376:51: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] WARN_ONCE(1, "can't patch jump_label at %pS", (void *)entry->code); On sparc64, the jump_label entry->code field is of type u32, but pointers are 64-bit. Silence the warning by casting entry->code to an unsigned long before casting it to a pointer. This is also what the sparc jump label code does.
