From 5354edd286ea6e956b81da66c9dcc5e47028198e Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 22 Mar 2017 13:12:18 +0100 Subject: Revert "apic: save apic_delivered flag" This reverts commit 07bfa354772f2de67008dc66c201b627acff0106. The global variable is only read as part of a apic_reset_irq_delivered(); qemu_irq_raise(s->irq); if (!apic_get_irq_delivered()) { sequence, so the value never matters at migration time.
