Greeting,

FYI, we noticed the following commit (built with gcc-9):

commit: 3756dbdf6f5c54834af10d2115328c65f7862920 ("[RFC PATCH] x86/cpu: Do not check c->initialized in topology_phys_to_logical_die()")
url: https://github.com/0day-ci/linux/commits/Borislav-Petkov/x86-cpu-Do-not-check-c-initialized-in-topology_phys_to_logical_die/20210105-193922
base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git 300da924c996f9b727ddde11865fc0e098c34223

in testcase: will-it-scale
version: will-it-scale-x86_64-6b6f1f6-1_20210108
with following parameters:

	nr_task: 100%
	mode: thread
	test: futex1
	cpufreq_governor: performance
	ucode: 0x2006a08

test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale


on test machine: 104 threads Skylake with 192G memory

caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
