On my perf/urgent branch (upstream should be the same):

[acme@five perf]$ patch -p1 < /wb/1.patch
patching file tools/perf/util/metricgroup.c
Hunk #1 succeeded at 150 with fuzz 2 (offset 1 line).
Hunk #2 succeeded at 192 (offset 1 line).
Hunk #3 succeeded at 223 (offset 1 line).

I'm fixing it up, please check that doing this is safe on your side.
