Many thanks for that pointer.

So, as alternative to dropping the DT interrupts property above, I could
also work around this issue by commenting out
vgic-init.c:vgic_init_cpu_starting()'s enable_percpu_irq() call.

Otherwise I am seeing the following call flow:

cpuhp_setup_state() -> __cpuhp_setup_state_cpuslocked() ->
cpuhp_issue_call() -> cpuhp_invoke_ap_callback() -> __cpuhp_kick_ap() ->
wait_for_ap_thread() -> wait_for_completion() --- doesn't return

With kvm_info() / printk():
