Loading kernel module on samsung s9 device

Question

I trying to load simple kernel module like "hello world" program without success. The file helloworld.c looks like:

#include <linux/module.h>       /* Needed by all modules */
#include <linux/kernel.h>       /* Needed for KERN_INFO */

int init_module(void)
{
        printk(KERN_INFO "Hello world\n");

        return 0;
}

void cleanup_module(void)
{
        printk(KERN_INFO "Goodbye world\n");
}

MODULE_LICENSE("GPL");
MODULE_INFO(intree, "Y");

The Makefile looks like the following:

obj-m += helloworld.o

ARCH := arm64
CROSS := /home/user/Desktop/toolchains/standalone/aarch64-linux-android-4.9/bin/aarch64-linux-android-
KDIR := ../..
PWD := $(shell pwd)

default:
        $(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS) -C $(KDIR) M=$(PWD) modules

clean:
        $(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS) -C $(KDIR) M=$(PWD) clean

Unfortunately, while I loading the helloworld.ko binary file I'm getting page fault exception. This is what I see in "/proc/last_kmsg":

Maybe I need to pass anything to KCFLAGS of add/remove feature to the kernel?
