perf tools: Recognize hugetlb mapping as anon mapping Hugetlbfs mapping should be recognized as anon mapping so user has a chance to create /tmp/perf-<pid>.map file for symbol resolving. This patch utilizes MAP_HUGETLB to identify hugetlb mapping. After this patch, if perf is started before a program starts using huge pages (so perf gets MMAP2 events from kernel), perf is able to recognize hugetlb mapping as anon mapping.
