aaf84465fc [TG3]: Clear GPIO mask before storing.
The GPIO settings may change during reset and so the stored values in
tp->grc_local_ctrl should be cleared first.

989a9d239c [TG3]: Improve NVRAM sizing.
This patch changes the NVRAM sizing procedure so that the driver can
take advantage of devices with 1:1 NVRAM strapping configurations.  This
is useful in cases where the traditional NVRAM sizing method fails.  In
the event that the flash size cannot be determined, the largest known
NVRAM size is used.  The patch also removes support for 5755 NVRAM
devices that are not supported by Broadcom and adds explicit sizing for
this device.

c13e371385 [TG3]: Fix TSO bugs.
1. Remove the check for skb->len greater than MTU when doing TSO.
When the destination has a smaller MSS than the source, a TSO packet
may be smaller than the MTU and we still need to process it as a TSO
packet.

2. On 5705A3 devices with TSO enabled, the DMA engine can hang due to a
hardware bug.  This patch avoids the hanging condition by reducing the
DMA burst size.

cf130cb102 [NETLINK]: Remove references to process ID
People treating the *_pid fields in netlink as a process ID has caused
endless confusion over the years.  The fact that our own netlink.h
does this only adds to the confusion.

So here is a patch to change the comments to refer to it as the port
ID which hopefully will make it clear what the purpose of the fields
really is.

6cbf0c704d iomap: make the default iomap functions fail softer
We used to BUG_ON() for a badly mapped IO port, which is certainly
correct, but actually made it harder to debug the case where the ATA
drivers had incorrectly mapped a nonconnected ATA port.

So make badly mapped ports trigger a WARN_ON(), and throw the IO away
instead (and return all ones for reads).  For things like broken driver
initialization - which is the most likely cause anyway - that should
mean that the machine comes up and is usable (at least that was the case
for the ATA breakage that triggered this patch).

It tends to be a whole lot easier to do a "dmesg" on a working machine
than to try to capture logs off a dead one.

8b6aaab8c8 m68k: macmace fixes
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.

0251c38ce5 CUDA ADB fixes
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).

d95fd5fce8 m68k: Mac II ADB fixes
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.

217f6710c2 m68k: Mac IRQ cleanup
There are no slow IRQs on Macs since Roman Zippel's IRQ reorganisation that
went into 2.6.16 and removed mac_irq_list[] and the do_mac_irq_list()
dispatcher. (They were implemented in do_mac_irq_list() by lowering the IPL.)
Hence there's no more use for mutual exclusion in the Mac interrupt
dispatchers. Remove it.

cd713ddc93 m68k: Mac nubus IRQ fixes (plan E)
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

67dfb153a3 m68k: Mac IRQ prep
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.

Make the interrupt dispatch loops terminate sooner.

Explicitly initialise the VIA latches to make the code more easily understood.

Also some cleanups.
