+ * This file is subject to the terms and conditions of the GNU General Public
+ * License. See the file COPYING in the main directory of this archive
+ * for more details.
+ *
+ * 11/07/96: rewritten interrupt handling, irq lists are exists now only for
+ * this sources where it makes sense (VERTB/PORTS/EXTER) and you must
+ * be careful that dev_id for this sources is unique since this the
+ * only possibility to distinguish between different handlers for
+ * free_irq. irq lists also have different irq flags:
+ * - IRQ_FLG_FAST: handler is inserted at top of list (after other
+ * fast handlers)
+ * - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
+ * they're executed irq level is set to the previous
+ * one, but handlers don't need to be reentrant, if
+ * reentrance occurred, slow handlers will be just
+ * called again.
+ * The whole interrupt handling for CIAs is moved to cia.c
+ * /Roman Zippel
+ *
+ * 07/08/99: rewamp of the interrupt handling - we now have two types of
+ * interrupts, normal and fast handlers, fast handlers being
+ * marked with SA_INTERRUPT and runs with all other interrupts
+ * disabled. Normal interrupts disable their own source but
+ * run with all other interrupt sources enabled.
+ * PORTS and EXTER interrupts are always shared even if the
+ * drivers do not explicitly mark this when calling
+ * request_irq which they really should do.
+ * This is similar to the way interrupts are handled on all
+ * other architectures and makes a ton of sense besides
+ * having the advantage of making it easier to share
+ * drivers.
