my device is samsung n8000   

android version : 4.0.4

kernel version : 3.0.15-962322



i want to make a "hello world " kernel module .   

git clone https://android.googlesource.com/kernel/samsung.git   to get 
source code . and make it .


hello world code

#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 1.\n");
>
>       /* 
>        * A non 0 return means init_module failed; module can't be loaded. 
>        */
>       return 0;
> }
>
> void cleanup_module(void)
> {
>       printk(KERN_INFO "Goodbye world 1.\n");
> }

make

obj-m += hello-1.o

all:
        make -C /opt/kernel/samsung M=$(PWD) modules

clean:
        make -C /opt/kernel/samsung M=$(PWD) clean


ARCH=arm 
CROSS_COMPILE=/opt/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi- 
make

and make success   .  

but when i push ko to device 

su 

insmod  hello.ko 

insmod: init_module 'hello.ko ' failed (Exec format error)
