Hi,
We have seen that the warning “sched: CPU #20's llc-sibling CPU #0 is not on
the same node! [node: 1 != 0]. Ignoring dependency. ” applies to 5.4 but we don’t
observe the fix in 5.4. I'm sending this email to apply the fix from upstream
2c88d45edbb8 ("x86, sched: Treat Intel SNC topology as default, COD as
exception") to 5.4 and also resolve the dependency conflict caused by
prerequisite commit adefe55e7258 ("x86/kernel: Convert to new CPU match
macros”) by keeping the later code base, please refer to the
previous two patches for the detail.
Thanks,
Sherry

I have no idea what you want me to do here, sorry.
Please provide a working, tested, set of patches backported to the
relevant stable trees you want to see them applied to, and I will be
glad to review and queue them up if they look good. No one here is in
the position to "resolve the dependency conflict" of anything here for
you, sorry, you will need to do this yourself as you are in the best
position to do so.
thanks!
