    PIC: Acknowledge interrupts more carefully
    
    Specs seems to be saying that we should mask an irq out while
    acknowledging it with EOI. Also, better acknowledge only the concerned
    irq.
    
    * i386/i386at/interrupt.S (interrupt): Mask irq before notifying EOI.
    Using specific EOI instead of unspecific EOI.
