- * arch/ppc/kernel/irq.c
- *
- * Derived from arch/i386/kernel/irq.c
- * Copyright (C) 1992 Linus Torvalds
- * Adapted from arch/i386 by Gary Thomas
- * Copyright (C) 1995-1996 Gary Thomas (gdt@linuxppc.org)
- * Updated and modified by Cort Dougan <cort@fsmlabs.com>
- * Copyright (C) 1996-2001 Cort Dougan
- * Adapted for Power Macintosh by Paul Mackerras
- * Copyright (C) 1996 Paul Mackerras (paulus@cs.anu.edu.au)
- * Amiga/APUS changes by Jesper Skov (jskov@cygnus.co.uk).
- *
- * This file contains the code used by various IRQ handling routines:
- * asking for different IRQ's should be done through these routines
- * instead of just grabbing them. Thus setups with different IRQ numbers
- * shouldn't result in any weird surprises, and installing new handlers
- * should be easier.
- *
- * The MPC8xx has an interrupt mask in the SIU. If a bit is set, the
- * interrupt is _enabled_. As expected, IRQ0 is bit 0 in the 32-bit
- * mask register (of which only 16 are defined), hence the weird shifting
- * and complement of the cached_irq_mask. I want to be able to stuff
- * this right into the SIU SMASK register.
- * Many of the prep/chrp functions are conditional compiled on CONFIG_8xx
- * to reduce code space and undefined function references.
