Florian Westphal d2c806abcf netfilter: conntrack: use siphash_4u64
This function is used for every packet, siphash_4u64 is noticeably faster
than using local buffer + siphash:

Before:
  1.23%  kpktgend_0       [kernel.vmlinux]     [k] __siphash_unaligned
  0.14%  kpktgend_0       [nf_conntrack]       [k] hash_conntrack_raw
After:
  0.79%  kpktgend_0       [kernel.vmlinux]     [k] siphash_4u64
  0.15%  kpktgend_0       [nf_conntrack]       [k] hash_conntrack_raw

In the pktgen test this gives about ~2.4% performance improvement.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
