x86: Tell irq work about self IPI support x86 supports irq work self-IPIs when local apic is available. This is partly known on runtime so lets implement arch_irq_work_has_interrupt() accordingly. This should be safely called after setup_arch(). Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Paul E.
