From b813ea9a14eaa9a6c071a9ab48a18d9a17dcef08 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sun, 22 May 2016 01:45:35 -0700 Subject: [PATCH] x86: broadwell: Correct I/O APIC ID Currently ID 2 is assgined to broadwell I/O APIC, however per chromebook_samus.dts 2 is the core#2 LAPIC ID. Now we change I/O APIC ID to 4 to avoid conflict.
