Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable

Subject: [PATCH] examples/performance-thread: fix build on FreeBSD 10.0

[ upstream commit b7162fee8811461fb87dd9c5b843b3d1ba283e5c ]

While later releases in the FreeBSD 10 series have a CPU_COUNT macro
defined, FreeBSD 10.0 and 10.1 do not have this macro. Therefore we provide
a basic fallback implementation of the macro for platforms where it is not
defined.

Fixes: 433ba6228f9a ("examples/performance-thread: add pthread_shim app")
