> 
> This patchset sets the minimum instruction set level for x86 platform to
> SSE4.2, up from SSE3. This means that all builds will have SSE4.2 support
> included, and we can remove special case manipulation of CFLAGS for the
> same. Naturally, this does mean that some machines that previously could
> run DPDK now can't do so, but hardware with SSE4.2 has been around for
> almost a decade now, so this should not be a major problem.
