crypto: replace FSF address with web source in license notices A few years ago the FSF moved and "59 Temple Place" is wrong. Having this still in our source files feels old and unmaintained. Let's take the license statement serious and not confuse users. As https://www.gnu.org/licenses/gpl-howto.html suggests, we replace the postal address with "<http://www.gnu.org/licenses/>".

[CRYPTO] xcbc: Fix crash when ipsec uses xcbc-mac with big data chunk The kernel crashes when ipsec passes a udp packet of about 14XX bytes of data to aes-xcbc-mac. It seems the first xxxx bytes of the data are in first sg entry, and remaining xx bytes are in next sg entry. But we don't check next sg entry to see if we need to go look the page up. I noticed in hmac.c, we do a scatterwalk_sg_next(), to do this check and possible lookup, thus xcbc.c needs to use this routine too. A 15-hour run of an ipsec stress test sending streams of tcp and udp packets of various sizes, using this patch and aes-xcbc-mac completed successfully, so hopefully this fixes the problem.
