sys_init_module() calls load_mod().
load_mod() allocates a region for module->module_init (grep for
mod->module_init = ptr and see the context) and copies the section of
the ELF file into this region (grep dest = mod->module_init and see the
context).
sys_init_module() calls the init function of the module (grep for ret =
mod->init()) and at the end frees mod->module_init (grep for
module_free(mod, mod->module_init)).
