x86: drop -funroll-loops for csum_partial_64.c Impact: performance optimization I did some rebenchmarking with modern compilers and dropping -funroll-loops makes the function consistently go faster by a few percent. So drop that flag. Thanks to Richard Guenther for a hint. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
