函数名称：lapic_assign_system_vectors

函数原型：void __init lapic_assign_system_vectors(void)

返回类型：void

参数：无

679  vector等于0
681  same as for_each_set_bit() but use bit as value to start with (vector, system_vectors, NR_VECTORS)
682  irq_matrix_assign_system(vector_matrix, vector, false)
684  如果nr_legacy_irqs()大于1则lapic_assign_legacy_vector(8259A PIC related value , false)
688  irq_matrix_online(vector_matrix)
691  以i小于nr_legacy_irqs()循环
692  如果i不等于8259A PIC related value 则irq_matrix_assign(vector_matrix, Vectors 0x30-0x3f are used for ISA interrupts.* round up to the next 16-vector boundary(i))
