From 6532ce994c304835f3bfc8479acce9d102cd8b5b Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 9 Jun 2014 16:19:47 +0800 Subject: [PATCH] x86: ce4100, irq: Do not set legacy_pic to null_legacy_pic Intel CE4100 platforms has i8259 legacy interrupt controllers, so don't set legacy_pic to null_legacy_pic in late booting stage because we need legacy_pic to mask i8259 pins when enabling IOAPIC pins for safety.
