This patch adds the array length of "free_area.free_list" to the vmcoreinfo data so that makedumpfile (dump filtering command) can exclude all free pages in linux-2.6.24. makedumpfile creates a small dumpfile by excluding unnecessary pages for the analysis. To distinguish unnecessary pages, makedumpfile gets the vmcoreinfo data which has the minimum debugging information only for dump filtering. In 2.6.24-rc1 or later, the free_area.free_list is an array which has one list for each migrate types instead of a single list. makedumpfile needs the array length of "free_area.free_list" and the vmcoreinfo data should contain it.
