Omg yes i see what you mean, when i extracted out the /proc/kallsyms from my phone and
compared it with the System.map file i made, the addresses are different, as shown
below:

For example from the above:
c000829c t init_setup | c0008290 t init_setup
The kallsyms file point the init_setup to c0000829c but the System.map file i compiled
myself points it to a different address.
That was just a small extract of the differences when i ran sdiff between the kallsyms
file (on the left) and the System.map file i compiled myself (on the right). Okay i
understand now, what should i do? The original kernel source code/headers didn't come
with a System.map file for me. Any help/suggestion would be deeply appreciated thank
you.

Hello,
Based on your previous email it still looks like you compiled a kernel yourself:
"#make ARCH=arm CROSS_COMPILE=$CCOMPILER EXTRA_CFLAGS=-fno-pic
modules_prepare"
This will produce a different System.map than than produced by the
original kernel compilation. Can you see if the addresses of symbols
in your System.map file match those of /proc/kallsyms on the running
device?
