Sasha, please drop this. The CXL subsystem is still in major feature
development. I would rather manually backport small fixes rather than
backport major code movement just to make small fix backport easier.

Let me know if there was a specific fix autosel was trying to resolve
and we'll take a look at whether it makes sense to do a custom
backport for -stable.
