Subject: [PATCH 0/3] perf_event: fix getting symbol error if kernel is relocatable

Hi,

If the kernel is relocatable, perf tools can't get symbol
name correctly, See: http://lkml.org/lkml/2009/12/20/218

The purpose of this patchset is to fix this bug, and it base
on my previously patchset: http://lkml.org/lkml/2009/12/29/4
since it used 'inject' event
