Thats correct. And which is why I am holding my other patchset which
actually move rte_eal_xx_iopl() stuff into arch specifics. I don't wanted
to mix two topic in this series. Waiting for this series to get merged then
abstract things like, iopl() and move "sys/io.h" in arch specifics and get
rid of few ifdef X86 clutter across dpdk code.
