This fixes some totally illogical and wrong code that converts things to
and from BCD mode essentially randomly, does math on values in BCD mode
etc etc. Introduce a few helper functions to make it a bit more obvious
what is going on, and make sure that we always do all the arithmetic
(and anythign else, for that matter) in binary, not BCD.
Tested by Mark Lord, who found the problem originally, and also pushed

the NULL dereference is here:
(gdb) list *0xffffffff804a9504
0xffffffff804a9504 is in natsemi_poll (drivers/net/natsemi.c:717).
712 return count;
713 }
714
715 static inline void __iomem *ns_ioaddr(struct net_device *dev)
716 {
717 return (void __iomem *) dev->base_addr;
718 }
719
which is this code from natsemi.c:
2227 struct net_device *dev = np->dev;
2228 void __iomem * ioaddr = ns_ioaddr(dev);
2229 int work_done = 0;
seems like the NAPI changes in -rc1 added an np->dev field but forgot to
initialize it ...
does the patch below fix the oops for you?

[NET]: Make NAPI polling independent of struct net_device objects.
added np->dev to drivers/net/natsemi.c's struct netdev_private, but
forgot to initialize that new field upon driver init. The result was
a predictable NULL dereference oops the first time the hardware
generated an interrupt.

P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726
hardwired to the second port of AHCI controller at PCI device 1f.2.
The 4726 doesn't work as PMP but as a storage processor which can do
hardware RAID on downstream ports.
When no device is attached to the downstream port of the 4726, pseudo
ATA device for configuration appears. Unfortunately, ATA emulation on
the device is very lousy and causes long hang during boot.
This patch implements workaround for the board. If the mainboard is
P5W-DH Deluxe (matched using DMI), only hardreset is used on the
second port of AHCI controller @ 1f.2 and the hardreset doesn't depend
on receiving the first FIS and just proceed to IDENTIFY.
This workaround fixes bugzilla #8923.

Local variable @action usage in ata_eh_reset() is a bit confusing.
It's used only to cache ehc->i.action to test reset masks after
clearing it; however, due to the generic name "action", it's easy to
misinterpret the local variable as containing the selected reset
method later. Also, the reason for caching the original value is easy
to miss.
This patch renames @action to @tmp_action and make it buffer newly
selected value instead to improve readability.

vendor.
* Force enable of IDE channels (used to be left alone as BIOS

* Change initial phase behavior of PIO cycle such that the host pulls
down the bus instead of tristating it. Vendor recommends this
setting.
The above settings are better for the current generation of

Did a complete audit of these and found we have another error case.
ata_bus_softreset calls ata_check_status which means that it tries to do
an ioread8 on the port blindly and check versus 0xFF for an error.
It should of course be using the ap->ops method for this via chk_status,
and this bug causes a wrog status call on the NS87415 at least.

Convert mii (link state) monitor to acquire correct locks for
failover events. In particular, failovers generally require RTNL at a low
level (when manipulating device MAC addresses, for example) and no other
locks. The high level monitor is responsible for acquiring a known set
of locks, RTNL, the bond->lock for read and the slave_lock for write, and
the low level failover processing can then release appropriate locks as
needed. This patch provides the high level portion.
As it is undesirable to acquire RTNL for every monitor pass (which
may occur as often as every 10 ms), the miimon has been converted to
do conditional locking. A first pass inspects all slaves to determine
if any action is required, and if so, a second pass (after acquring RTNL)
is done to perform any actions (doing a complete rescan, as the situation
may have changed when all locks were released).

Change locking in balance-rr transmit processing to use a free
running counter to determine which slave to transmit on. Instead, a
free-running counter is maintained, and modulo arithmetic used to select
a slave for transmit.
This removes lock operations from the TX path, and eliminates
a deadlock introduced by the conversion to work queues.

Polling currently calls the irq handler, which loops through all the
boards, calling the work function for all polling boards with work.
irq handling loops through all the boards, finding the specific board
that applies to us, and calling the work just for that one board.
The two logics are sufficiently different to warrant different
functions, rather than being slack and calling the same function in two
different ways.
This serves to make the interrupt handler a -lot- more efficient.
