Could you also backport these two commits adefe55e7258 ("x86/kernel: Convert to new CPU match macros") 2c88d45edbb8 ("x86, sched: Treat Intel SNC topology as default, COD as exception") to 5.4.y?
Commit adefe55e7258 ("x86/kernel: Convert to new CPU match macros") is a prerequisite of the second commit. There are conflicts while cherry-picking commit adefe55e7258 ("x86/kernel: Convert to new CPU match macros"), which are caused by a later commit c84cb3735fd5 ("x86/apic: Move TSC deadline timer debug printk"). Keep the later code base.

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!
