2009-11-24T05:26:23Z

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.
