lookup_address ---> arm
I wrote a linux module to intercept system calls and communicate with a userspace application. To make sys_call_table memory writable(readonly by default) I used lookup_address (method I saw in Alexey's blog) it works perfect for x86 platform however i needed it for pandaboard (arm architecture) when I crosscompiled it doesnt support ---> lookup_address() <--- function which is used to make sys_call_table writable. Any idea why???. Using compiler arm-angstrom-linux-gnueabi-
