From: Paolo Bonzini
Subject: [Qemu-devel] [PULL 06/12] ioapic: clear irq_eoi when updating the ioapic redirect table entry
Date: Fri, 5 Jul 2019 21:50:33 +0200

From: Li Qiang <address@hidden>

irq_eoi is used to count the number of irq injected during eoi
broadcast. It should be set to 0 when updating the ioapic's redirect
table entry.
