The current problem is that when crosscompiling we get a different _padding_ due to file2alias.c being compiled with HOSTCC. What you are talking about is a different issue, and I can't talk about it since I don't understand these interactions between modpost and depmod. > Sam cu Adrian -- "Is there not promise of rain?"
