Richard Chang c8b3600312 mm: add alloc_contig_migrate_range allocation statistics ... alloc_contig_migrate_range has every information to be able to understand big contiguous allocation latency. For example, how many pages are migrated, how many times they were needed to unmap from page tables. This patch adds the trace event to collect the allocation statistics. In the field, it was quite useful to understand CMA allocation latency.
