From: Kan Liang <kan.liang@linux.intel.com>
Display the page size if it is available.
Can be configured by the user, for example: perf script --fields comm,event,phys_addr,page_size dtlb mem-loads:uP: 3fec82ea8 4K dtlb mem-loads:uP: 3fec82e90 4K dtlb mem-loads:uP: 3e23700a4 4K dtlb mem-loads:uP: 3fec82f20 4K dtlb mem-loads:uP: 3e23700a4 4K dtlb mem-loads:uP: 3b4211bec 4K dtlb mem-loads:uP: 382205dc0 2M dtlb mem-loads:uP: 36fa082c0 2M dtlb mem-loads:uP: 377607340 2M dtlb mem-loads:uP: 330010180 2M dtlb mem-loads:uP: 33200fd80 2M dtlb mem-loads:uP: 31b012b80 2M
