I found the do_div issues in llog.c has already been fixed in master (LU-6134). Its just missing from b2_8_fe. The other do_div bug was introduced with the move to 64 bit time upstream. I submitted a patch here that moves to 64 bit time and resolves the do_div issue. I submitted to master so people can review this work to make sure I did it right,
