Comment 3 for bug 608775

Some patches merged into Arnaldo's perf/core branch at git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux-2.6.git:

perf report: Don't abbreviate file paths relative to the cwd
http://git.kernel.org/?p=linux/kernel/git/acme/linux-2.6.git;a=commitdiff;h=361d13462585474267a0c41e956f1a1c19a93f17

perf tools: Remove unneeded code for tracking the cwd in perf sessions
http://git.kernel.org/?p=linux/kernel/git/acme/linux-2.6.git;a=commitdiff;h=88ca895dd4e0e64ebd942adb7925fa60ca5b2a98

There is still a problem with the build-id based caching done in new versions of the tools.

This can be disabled by passing --no-buildid-cache to perf record (bit if there are stale files in ~/.debug you may still need to delete them in order for perf report to work properly).

I'm currently looking into a more complete fix for this.
