From 16d7a191170f0ca48c2c3277017b3e6d275e0711 Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Tue, 21 Apr 2009 17:45:10 +0300 Subject: [PATCH] KVM: Fix userspace IRQ chip migration Re-put pending IRQ vector into interrupt_bitmap before migration. Otherwise it will be lost if migration happens in the wrong time.
