Subject: eal: remove unneeded conditionals for SSE headers
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f46e442ca01539ff83bf8726e873d170c3eb87f3;p=dpdk.git

eal: remove unneeded conditionals for SSE headers

Our x86 baseline is to have support for SSE4.2, so therefore there is no
point in conditions around the inclusion of SSE1 - SSE4 headers.
