Subject: [GIT PULL 0/2] perf session fix host_machine handling wrt build ids
Hi Ingo,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux-2.6 perf
Stephane and Tom,
Now the build id code should be back working:
[root@...pio linux-2.6-tip]# rm -rf /root/.debug/
[root@...pio linux-2.6-tip]# perf record find / > /dev/null
^C[ perf record: Woken up 3 times to write data ]
[ perf record: Captured and wrote 0.667 MB perf.data (~29163 samples) ]

perf symbols: Don't try to read the build-id twice
perf session: Make read_build_id routines look at the host_machine too
