Clock task split - preemption handled in the clock timer interrupt handler, not in the clock task - more achitecture independent clock timer handling code - smp ready as each CPU can have its own timer 2009-11-06 10:04:15 +01:00			`#ifndef __CLOCK_X86_H__`

SMP - Only a single APIC timer handler - bsp_timer_int_handler() and ap_timer_int_handler() unified into timer_int_handler() - global realtime updated only on BSP 2010-09-15 16:10:09 +02:00			`#include "../apic_asm.h"`
