Linux 4.9.75

[Greg KH]

I'm announcing the release of the 4.9.75 kernel.

All users of the 4.9 kernel series must upgrade.

As with the 4.4.110 release, please test.  This -rc cycle was much
calmer than 4.4.y, but that doesn't mean the same issues are not still
there.  Again, if you have problems, please let me know.

The updated 4.9.y git tree can be found at:
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.9.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
