commit d0528b5d71faf612014dd7672e44225c915344b2

perf tools: Add anonymous huge page recognition
Judging anonymous memory's vm_area_struct, perf_mmap_event's filename
will be set to "//anon" indicating this vma belongs to anonymous
memory.
Once hugepage is used, vma's vm_file points to hugetlbfs. In this way,
this vma will not be regarded as anonymous memory by is_anon_memory() in
perf user space utility.
