I'm announcing the release of the 4.14.65 kernel.

All x86 users of the 4.14 kernel series must upgrade.

The updated 4.14.y git tree can be found at:
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.14.y
and can be browsed at the normal kernel.org git web browser:
	http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary

thanks,

greg k-h
