ps3av:
- Move the definition of struct ps3av to ps3av.c, as it's locally used only.
- Kill ps3av.sem, use the existing ps3av.mutex instead.
- Make the 512-byte buffer in ps3av_do_pkt() static to reduce stack usage.
Its use is protected by a semaphore anyway.

Install the built-in macsonic interrupt handler on both IRQs when using
via_alt_mapping. Otherwise the rare interrupt that still comes from the
nubus slot will wedge the nubus.
$ cat /proc/interrupts
auto 2: 89176 via2
auto 3: 744367 sonic
auto 4: 0 scc
auto 6: 318363 via1
auto 7: 0 NMI
mac 9: 119413 framebuffer vbl
mac 10: 1971 ADB
mac 14: 198517 timer
mac 17: 89104 nubus
mac 19: 72 Mac ESP SCSI
mac 56: 629 sonic
mac 62: 1142593 ide0
Version 1 of this patch had a bug where a nubus sonic card would register
two interrupt handlers. Only a built-in sonic needs both.
Versions 2 and 3 needed some cleanups, as Raylynn Knight and Christoph
Hellwig pointed out (thanks).

Fix a race condition in the transmit code, where the dma interrupt could update
the free tx buffer count concurrently and wedge the tx queue.
Fix the misuse of the rx frame status and rx frame length registers: no more
"fifo overrun" errors caused by the OFLOW bit being tested in the frame length
register (instead of the status register), and no more missed packets due to
incorrect length taken from status register (instead of the frame length
register).
Fix a panic (skb_over_panic BUG) caused by allocating and then copying an
incoming packet while the packet length register was changing.
Cut-and-paste the reset code from the powermac mace driver (mace.c), so the NIC
functions when MacOS does not initialise it (important for anyone wanting to
use the Emile boot loader).
Cut-and-paste the error counting and timeout recovery code from mace.c.
Fix over allocation of rx buffer memory (it's page order, not page count).
Converted to driver model.
Converted to DMA API.
Since I've run out of ways to make it fail, and since it performs well now,
promote the driver from EXPERIMENTAL status. Tested on both quadra 840av and
660av.

Fix the flakiness in the CUDA ADB driver on m68k macs (keypresses getting
wedged down or ADB just going AWOL altogether).
The only IRQ used by this driver is the VIA shift register IRQ. The PowerMac
conditional code disables the other VIA IRQ sources, so don't mess with the
other IRQ flags in the common code -- m68k macs need them.
When polling, don't disable local interrupts when we only need to disable the
CUDA interrupt.
Unless polling, don't clear the shift register IRQ flag. On m68k macs this
creates a race that often breaks CUDA ADB.
Tested on Quadra 840av and LC630 (both m68k); also Beige G3 (powerpc).

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
ST_ODD).
Add some commentry.
Add a generous quantity of sanity checks (BUG_ONs).
Let m68k macs use the adb_sync boot param too.
Tested on Mac II, Mac IIci, Quadra 650, Quadra 700 etc.

SCSI should be working on a TT (but someone should really try!) but causes
trouble on a Falcon (as in: it ate a filesystem of mine) at least when
used concurrently with IDE. I have the notion it's because locking of the
ST-DMA interrupt by IDE is broken in 2.6 (the IDE driver always complains
about trying to release an already-released ST-DMA). Needs more work, but
that's on the IDE or m68k interrupt side rather than SCSI.
