From 336224ba5e4fb42a95d02ab0aa0fdff21649bb38 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Wed, 26 Sep 2012 12:44:34 +0200 Subject: x86, apic: Mask IO-APIC and PIC unconditionally on LAPIC resume IO-APIC and PIC use the same resume routines when IRQ remapping is enabled or disabled. So it should be safe to mask the other APICs for the IRQ-remapping-disabled case too.
