--- Comment #4 from Tomi Sarvela <tomix.p.sarvela at intel.com> ---
Changing HOTPLUG_CPU and ACPI_HOTPLUG_CPU is not enough to keep this lock out
of code. Looking at Kconfig: (disabling PM is counterproductive to testing PM
functionality with IGT)

config HOTPLUG_CPU
        bool "Support for hot-pluggable CPUs"
        depends on SMP
        ---help---
          Say Y here to allow turning CPUs off and on. CPUs can be
          controlled through /sys/devices/system/cpu.
          ( Note: power management support will enable this option
            automatically on SMP systems. )
          Say N if you want to disable CPU hotplug.
