Subject: examples/distributor: fix build for non-x86 arch
X-Git-Tag: spdx-start~7634
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=64502fab90ce1a3150c9db6e1c2c27201945e74d;p=dpdk.git

examples/distributor: fix build for non-x86 arch

_mm_prefetch is defined only in x86 compilers.
Use rte_prefetch_non_temporal() abstraction instead of _mm_prefetch(x, 0)
to in-order to build distributor application for non x86 platforms
