From 74afab7af7d9aeba86b3b8e39670cf7d0058f6df Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 27 Oct 2014 16:12:00 +0800 Subject: x86, irq: Move local APIC related code from io_apic.c into vector.c Create arch/x86/kernel/apic/vector.c to host local APIC related code, prepare for making MSI/HT_IRQ independent of IOAPIC.
