the advent of ARMv6, this is far too limited.
Replace the page table flags with a memory type index, so that the
desired attributes can be selected from the mem_type table.
Finally, to prevent silent miscompilation due to the differing

GPIO and MPUIO wake updates:
- Hook MPUIOs into the irq wakeup framework too. This uses a platform
device to update irq enables during system sleep states, instead of
a sys_device, since the latter is no longer needed for such things.
- Also forward enable/disable irq wake requests to the relevant GPIO
controller, so the top level IRQ dispatcher can (eventually) handle
these wakeup events automatically if more than one GPIO pin needs to
be a wakeup event source.
- Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such
read-only data under the spinlock.
This assumes (maybe wrongly?) that only 16xx can do GPIO wakeup; without
a 15xx I can't test such stuff.
Also this expects the top level IRQ dispatcher to properly handle requests
to enable/disable irq wake, which is currently known to be wrong: omap1
saves the flags but ignores them, omap2 doesn't even save it. (Wakeup
events are, wrongly, hardwired in the relevant mach-omapX/pm.c file ...)
So MPUIO irqs won't yet trigger system wakeup.

Fix a crash caused by requests placed in the queue with the completed flag
already set. This lead to some ADB_SYNC requests returning early and their
request structs being popped off the stack while still queued. Stack corruption
ensued or an invalid request callback pointer was invoked or both. Eliminate
macii_retransmit() and its buggy implementation of macii_write(). Have
macii_queue_poll() fully initialise the request queues.
Fix a bug in macii_queue_poll() where the last_req pointer was not being set.
This caused some requests to leave the queue before being completed (and would
also corrupt the stack under certain conditions).
Fix a race in macii_start that could set the state machine to "reading" while
current_req was null.
No longer send poll commands with the ADBREQ_REPLY flag -- doing that caused
the replies to be stored in the request buffer where they were forgotten
about.
Don't autopoll by continuously sending new Talk commands. Get the controller to
do that for us. This reduces the ADB interrupt rate on an idle bus to about 5
per second. Only autopoll the devices that were probed.
Explicitly clear the interrupt flag when polling.
Use disable_irq rather than local_irq_save when polling.
Remove excess local_irq_save/restore pairs.
Improve bus timeout and service request detection.
Remove unused code (last_reply, adb_dir etc) and unneeded code (prefix_len,
first_byte etc).
Change TIP and TACK to their correct names on this ADB controller (ST_EVEN and

Some Macs lack a slot interrupt enable register. So the existing code makes
disabled and unregistered slot IRQ lines outputs set high. This seems to work
on quadras, but does not work on genuine VIAs (perhaps the card still succeeds
in pulling the line low, or perhaps because this increases the settle time on
the port A input, meaning that the CA1 IRQ could fire before the slot line
reads active).
Because of this, the nubus_active flags were used to mask IRQs, which is
actually worse than the problem it tries to solve. Any interrupt masked by
nubus_active will remain asserted and prevent further transitions on CA1. And
so the nubus gets wedged regardless of hardware (emulated VIA ASIC, real VIA
chip or RBV).
The best solution to this hardware limitation of genuine VIAs is to disable the
umbrella SLOTS IRQ when disabling a slot on those machines. Unfortunately, this
means all slot IRQs get disabled when any slot IRQ is disabled. But it is only
a problem when there's more than 1 device using nubus interrupts.
Another potential problem for genuine VIAs is an unregistered nubus IRQ.
Eventually it will be possible to enable the CA1 interrupt by installing its
handler only _after_ all nubus drivers have loaded but _before_ the kernel
needs them, at which time this last problem can be fixed. For now it can be
worked around:
- disable MacOS extensions
- don't boot MacOS (use the Emile bootloader instead)
- get the bootloaders to disable ROM drivers (Penguin does this for video
cards already, don't know about Emile)
- physically remove unsupported cards

Make sure that there are no slot IRQs asserted before leaving the nubus
handler. If there are and we don't then the nubus gets wedged because this
prevents a CA1 transition, which means no more nubus IRQs.
