# 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") # Reported-by: Paul Mackerras <paulus@samba.org> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> #
