函数名称：IO-APIC versions below 0x20 don't support EOI register

函数原型：static void __eoi_ioapic_pin(int apic, int pin, int vector)

返回类型：void

参数：

类型参数名称
intapic
intpin
intvector
512  如果mpc_ioapic_ver(apic)大于等于0x20则
513  io_apic_eoi(apic, vector)
514  否则
517  entry等于entry1等于__ioapic_read_entry(apic, pin)
522  0: enabled, 1: disabled 等于IOAPIC_MASKED
523  0: edge, 1: level 等于IOAPIC_EDGE
525  When we write a new IO APIC routing entry, we need to write the high* word first! If the mask bit in the low word is clear, we will enable* the interrupt, and we need to make sure the entry is fully populated* before that happens.
