tools/power turbostat: fix un-intended affinity of forked program
Linux 3.4 included a modification to turbostat to lower cross-call overhead by using scheduler affinity: 15aaa34654831e98dd76f7738b6c7f5d05a66430 (tools turbostat: reduce measurement overhead due to IPIs) In the use-case where turbostat forks a child program, that change had the un-intended side-effect of binding the child to the last cpu in the system. This change removed the binding before forking the child. This is a back-port of a fix already included in turbostat v2. Signed-off-by: Len Brown <len.brown@intel.com>
