Update to latest upstream stable release, Linux v4.6.4

For those with Skylake CPUs, please note that there may be instability with a recent microcode update. Read https://www.happyassassin.net/2016/07/07/psa-failure-to-boot-after-ker nel-update-on-skylake-systems/ and look for a system firmware update before installing the kernel.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
