Bug#708994: perf script net_dropmonitor reports complete nonsense

[Ben Hutchings <ben@decadent.org.uk>]

Package: linux-tools-3.2
Version: 3.2.17-1
Severity: normal
Tags: upstream

The net_dropmonitor script for perf doesn't look up symbols correctly,
e.g.:

                 LOCATION                    OFFSET                     COUNT
          __per_cpu_start                         0                       258
                   _stext      18446744071578810668                     27920
                   _stext      18446744071578811059                       132
                   _stext      18446744071578843530                        20
                   _stext      18446744071578843536                     39171

It's clearly doing the address comparison the wrong way round,  But there
seem to be further problems (like it isn't getting the right function
addresses at all).  That might be a bug in the kernel itself.
