Import Linux 6.5 (edge, stable) as a secondary version

Start offering support for Linux stable for users who might
experience problems with the long-term (LTS, currently 6.1) series
of kernels.  But it may also be handy to get more hardware support,
benefits of major changes in the stack, and get ready for the
adoption of the next long-term series.
