When enable LOCKDEP, static_obj() will cause error. Because some
__initdata static variables is before _stext:
static int static_obj(const void *obj)
{
unsigned long start = (unsigned long) &_stext,
end = (unsigned long) &_end,
addr = (unsigned long) obj;
/*
* static variable?
*/
if ((addr >= start) && (addr < end))
return 1;
