There is at least one patch in perf/urgent that should be applied before
this one:

commit ffb5e0fb44d0829021a51f972df90166bc9b700e
Author: Han Pingtian <phan@...hat.com>

    perf test: Use cpu_map->[cpu] when setting affinity

-----------------------------------------------------------

Attached goes a combined patch with everything that is not yet in
.38-rc2, please test it. It is all about fixing the build in old
distros and in some arches like ppc64 where using %L[dux] in printf
functions is problematic.

I just checkd out a fresh copy of 2.6.38-rc2 and applied and built with
it.
