8 * The following vectors are part of the Linux architecture, there
9 * is no hardware IRQ pin equivalent for them, they are triggered
10 * through the ICC by us (IPIs)

19 * every pentium local APIC has two 'local interrupts', with a
20 * soft-definable vector attached to both interrupts, one of
21 * which is a timer interrupt, the other one is error counter
22 * overflow. Linux uses the local APIC timer interrupt to get
23 * a much simpler SMP time architecture:
