Hi,

I just found the commit in 5.10 stable kernel.

commit 8a3fc32b322cc3081dd3569047c9834f496b4ab0
Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

     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.

v5.11-rc1
linux> git tag --sort=taggerdate --contain db865272d9c4 | head -1
v5.10-rc2

So I am wondering if the mentioned commit is suitable for 5.10 stable 
kernel, or what am I missing?

Thanks,
Guoqing
