Regressions on arm64 devices cpu hotplug tests failed with gcc-13 and
clang-20 the stable-rc 6.6.85-rc2

These regressions are the same as stable-rc 6.1 cpu hotplug regressions.

First seen on the 6.6.85-rc2
Good: v6.6.83
Bad: 6.6.85-rc2

* dragonboard 845c

- rseq_basic_percpu_ops_mm_cid_test
- rseq_basic_percpu_ops_test
- ltp-controllers: cpuset_hotplug_test.sh

Regression Analysis:
- New regression? yes
- Reproducibility? Yes

Test regression: arm64 arm cpuhotplug kernel NULL pointer dereference

Climb the mountain not to plant your flag, but to embrace the challenge,
enjoy the air and behold the view. Climb it so you can see the world,
not so the world can see you.                    -- David McCullough Jr.
