4.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Thomas Gleixner <t...@linutronix.de> commit 2b04e46d8d0b9b7ac08ded672e3eab823f01d77a upstream. To address the EBUSY fail of interrupt affinity settings in case that the previous setting has not been cleaned up yet, use the new apic_ack_irq() function instead of directly invoking ack_APIC_irq().
