The types of mm flags are now far beyond the core dump related features. This patch moves mm flags from linux/sched/coredump.h to linux/mm_types.h. The linux/sched/coredump.h has include the mm_types.h, so the C files related to coredump does not need to change head file inclusion. In addition, the inclusion of sched/coredump.h now can be deleted from the C files that irrelevant to core dump.
