I'm announcing the release of the 6.6.71 kernel.

It's only needed if you could not properly build 6.6.70 as there is a
configuration that is pretty common that would fail to build properly.
That is now resolved.  If you did not have a problem building 6.6.70, no
need to upgrade at this point in time.

The updated 6.6.y git tree can be found at:
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.6.y
and can be browsed at the normal kernel.org git web browser:
	https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary

thanks,

greg k-h
