The root cause is: for putback_lur_page() in mm/vmscan.c for next-20130621 tree. the compiler assumes "lru == LRU_UNEVICTABLE" instead of report warnings (uninitializing lru) The details are below, and the related info and warn are in attachments, please check, thanks. Next, I will compile gcc compiler with the gcc latest code, if also has this issue, I should communicate with gcc mailing list for it.
