#     powerpc/powernv: Fix CPU idle to be called with IRQs disabled
#     
#     Commit e78a7614f3876 ("idle: Prevent late-arriving interrupts from
#     disrupting offline") changes arch_cpu_idle_dead to be called with
#     interrupts disabled, which triggers the WARN in pnv_smp_cpu_kill_self.
#     
#     Fix this by fixing up irq_happened after hard disabling, rather than
#     requiring there are no pending interrupts, similarly to what was done
#     done until commit 2525db04d1cc5 ("powerpc/powernv: Simplify lazy IRQ
#     handling in CPU offline").
#     
#     Fixes: e78a7614f3876 ("idle: Prevent late-arriving interrupts from disrupting offline")
