commit 10db3cc6642ceef0ebeba467ff8834eb194f15d6 Author: Sepherosa Ziehau <sephe@dragonflybsd.org> Date: Sun Jan 30 14:33:52 2011 +0800 ioapic/icu: Rework PIC selection code - In the early stage, before I/O APIC is detected and setup, ICU controls interrupts, so all IDT entries should be set to ICU's intr code. - Switch to I/O APIC only after ICU is completely disconnected, i.e. after IMCR is set and LINT0 is masked.
