Since commit7dadeaa6e8("sched: Further restrict the preemption modes"), powerpc always has CONFIG_PREEMPTION because only CONFIG_PREEMPT and CONFIG_PREEMPT_LAZY are possible, even in dynamic preemption mode (see sched_dynamic_mode). As a consequence, need_irq_preemption() is always true and can be removed. And because commitbee25f97ad("powerpc: Enable GENERIC_ENTRY feature") includes linux/irq-entry-common.h which already declares sk_dynamic_irqentry_exit_cond_resched static key, asm/preempt.h becauses useless and can be removed.
