perf kmem: Add new option to show raw ip
Add option "--raw-ip" to show raw ip instead of symbols: # ./perf kmem --stat caller --raw-ip ------------------------------------------------------------------------------ Callsite |Total_alloc/Per | Total_req/Per | Hit | Frag ------------------------------------------------------------------------------ 0xc05301aa | 733184/4096 | 733184/4096 | 179| 0.000% 0xc0542ba0 | 483328/4096 | 483328/4096 | 118| 0.000% ... Also show symbols with format sym+offset instead of sym/offset.
