Hi,
I just found the commit in 5.10 stable kernel.
stable-linux> git tag --sort=taggerdate --contain 8a3fc32b322cc3081dd3569047c9834f496b4ab0 | head -1 v5.10.17

cpufreq: ACPI: Extend frequency tables to cover boost frequencies
commit 3c55e94c0adea4a5389c4b80f6ae9927dd6a4501 upstream.
[ ... ]
Fixes: 41ea667227ba ("x86, sched: Calculate frequency invariance for AMD systems") Fixes: 976df7e5730e ("x86, sched: Use midpoint of max_boost and max_P for frequency invariance on AMD EPYC") Fixes: db865272d9c4 ("cpufreq: Avoid configuring old governors as default with intel_pstate")
Except db865272d9c4 was applied in v5.10-rc2, the others (41ea667227ba and 976df7e5730e) were first appeared in v5.11-rc1.

So I am wondering if the mentioned commit is suitable for 5.10 stable kernel, or what am I missing?
Is it causing a problem for you? What is the issue with having it in the 5.10.y tree?
No.
I am trying to port 41ea667227ba and relevant commits to our kernel which is based on 5.10 stable kernel, and I am being asked to port 3c55e94c0ade per the fix tag after 41ea667227ba was added, then I was confused because of conflict.
Don't "port" stable kernels, just do a normal merge and then all is much better. That way you do not miss patches you should have applied but didn't realize until much later...
good luck!
