Set bits 0, 4, 5 and 7 of PCI configuration register 0x40 in the
quirk. This has the following effects and is recommended by the
vendor.
* Force enable of IDE channels (used to be left alone as BIOS
configured)
* 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
controllers and needed for the upcoming next generation.
Tested on JMB363.

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.

ICP's Wafer 5823 SBC has, as far as I can tell, the same WDT as many,
if not all ICP's SBC's (that do have a WDT). I have tested it with
several boards, including Rocky 4783, Rocky 3703 and Rocky 3782.
I propose a rename of the Wafer 5823 watchdog timer driver
to something like "IPC (SBC) Watchdog Timer", to reflect that it
works with other IPC boards (maybe even all of them).

UNDERRUN handling.
For recent ISPs, software during CS_UNDERRUN handling must
determine if the two residuals, firmware-calculated and FCP_RSP,
are different to recognize if a frame has been dropped. Update
the driver to catch this condition, and clear the
SS_RESIDUAL_UNDER and lscsi_status bits. This logic is
consistent with what earlier firmwares did by explicitly
cracking open the FCP_RSP statuses and clearing
SS_RESIDUAL_UNDER.

Since both NVRAM and VPD regions of the flash reside on unaligned

By introducing the use_dac(), set_dac() and DMA_DAC_MASK macros, we can
eliminate a lot of ifdefs from the code. We now rely on the compiler to
optimise away a few things that we'd formerly relied on the preprocessor
to do. This makes sym_setup_bus_dma_mask() small enough to inline into
its only caller.
