VUNPCKLPS (VEX.256 encoded version) AVX instruction mislabeled as UNPCKLPS

The Intel® 64 and IA-32 Architectures Software Developer’s Manual (http://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-software-developer-manual-325462.pdf) has a typo in page Vol. 2B 4-431 (page 1527 in the PDF): it lists "UNPCKLPS (VEX.256 encoded version)", which I believe should be "VUNPCKLPS (VEX.256 encoded version)". Also, it looks like there is a formatting error in that section that causes the definition of that operation to be included in the definition of the previous operation ("VUNPCKLPS (VEX.128 encoded version)")
