- * 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

- *           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 IRQF_DISABLED 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.

  * <asm/atariints.h>): Autovector interrupts are 1..7, then follow ST-MFP,
  * TT-MFP, SCC, and finally VME interrupts. Vector numbers for the latter can
  * be allocated by atari_register_vme_int().
- *
- * Each interrupt can be of three types:
- *
- *  - SLOW: The handler runs with all interrupts enabled, except the one it
- *    was called by (to avoid reentering). This should be the usual method.
- *    But it is currently possible only for MFP ints, since only the MFP
- *    offers an easy way to mask interrupts.
- *
- *  - FAST: The handler runs with all interrupts disabled. This should be used
- *    only for really fast handlers, that just do actions immediately
- *    necessary, and let the rest do a bottom half or task queue.
- *
- *  - PRIORITIZED: The handler can be interrupted by higher-level ints
- *    (greater IPL, no MFP priorities!). This is the method of choice for ints
- *    which should be slow, but are not from a MFP.
- *
- * The feature of more than one handler for one int source is still there, but
- * only applicable if all handers are of the same type. To not slow down
- * processing of ints with only one handler by the chaining feature, the list
- * calling function atari_call_irq_list() is only plugged in at the time the
- * second handler is registered.
- *
- * Implementation notes: For fast-as-possible int handling, there are separate
- * entry points for each type (slow/fast/prio). The assembler handler calls
- * the irq directly in the usual case, no C wrapper is involved. In case of
- * multiple handlers, atari_call_irq_list() is registered as handler and calls
- * in turn the real irq's. To ease access from assembler level to the irq
- * function pointer and accompanying data, these two are stored in a separate
- * array, irq_handler[]. The rest of data (type, name) are put into a second
- * array, irq_param, that is accessed from C only. For each slow interrupt (32
- * in all) there are separate handler functions, which makes it possible to
- * hard-code the MFP register address and value, are necessary to mask the
- * int. If there'd be only one generic function, lots of calculations would be
- * needed to determine MFP register and int mask from the vector number :-(
- *
- * Furthermore, slow ints may not lower the IPL below its previous value
- * (before the int happened). This is needed so that an int of class PRIO, on
- * that this int may be stacked, cannot be reentered. This feature is
- * implemented as follows: If the stack frame format is 1 (throwaway), the int
- * is not stacked, and the IPL is anded with 0xfbff, resulting in a new level
- * 2, which still blocks the HSYNC, but no interrupts of interest. If the
- * frame format is 0, the int is nested, and the old IPL value can be found in
- * the sr copy in the frame.

- *           Removed irq list support, if any machine needs an irq server

- *           - IRQ_FLG_LOCK : handler can't be replaced
- *           There are other machine depending flags, see there
- *           If you want to replace a default handler you should know what
