150 * much _has_ to be done exactly like this (mask it
228 outb(0xff, 0x21); /* mask all of 8259A-1 */
229 outb(0xff, 0xA1); /* mask all of 8259A-2 */
250 * in AEOI mode we just have to mask the interrupt
259 outb(cached_21, 0x21); /* restore master IRQ mask */
260 outb(cached_A1, 0xA1); /* restore slave IRQ mask */
