Since commit 368c73d4 the kernel will try
to update the non-writeable BAR registers 0..3 of PIIX4 IDE adapters if
pci_assign_unassigned_resources() is used to do full resource assignment of
the bus.  This fails because in the PIIX4 these BAR registers have
implicitly assumed values and read back as zero; it used to work because
the kernel used to just write zero to that register the read back value did
match what was written.

The fix is a new resource flag IORESOURCE_PCI_FIXED used to mark a resource
as non-movable.  This will also be useful to keep other import system
resources from being moved around - for example system consoles on PCI
busses.

This patch is designed to fix:
- Disk eating corruptor on KT7 after resume from RAM
- VIA IRQ handling
- VIA fixups for bus lockups after resume from RAM

The core of this is to add a table of resume fixups run at resume time.
We need to do this for a variety of boards and features, but particularly
we need to do this to get various critical VIA fixups done on resume.

The second part of the problem is to handle VIA IRQ number rules which
are a bit odd and need special handling for PIC interrupts. Various
patches broke various boxes and while this one may not be perfect
(hopefully it is) it ensures the workaround is applied to the right
devices only.

From: Jean Delvare <khali@linux-fr.org>

Now that PCI quirks are replayed on software resume, we can safely
re-enable the Asus SMBus unhiding quirk even when software suspend support
is enabled.

There are already several places in the kernel that want to search a PCI
device for a given Hypertransport capability. Although this is possible
using pci_find_capability() etc., it makes sense to encapsulate that
logic in a helper - pci_find_ht_capability().

To cater for searching exhaustively for a capability, we also provide
pci_find_next_ht_capability().

We also need to cater for the fact that the HT capability fields may be
either 3 or 5 bits wide. pci_find_ht_capability() deals with this for you,
but callers using the #defines directly must handle that themselves.

The current implementation of __pci_bus_find_cap() does two things,
first it determines the start of the capability chain for the device,
and then it trys to find the requested capability.

Split these out, so that we can use the two parts independantly in
a subsequent patch. Externally visible behaviour should be unchanged.

Unfortunately, the .../new_id feature does not work with the 8250_pci
driver.

The reason for this comes down to the way .../new_id is implemented.
When PCI tries to match a driver to a device, it checks the modules
static device ID tables _before_ checking the dynamic new_id tables.

When a driver is capable of matching by ID, and falls back to matching
by class (as 8250_pci does), this makes it absolutely impossible to
specify a board by ID, and as such the correct driver_data value to
use with it.

Let's say you have a serial board with vendor 0x1234 and device 0x5678.
It's class is set to PCI_CLASS_COMMUNICATION_SERIAL.

On boot, this card is matched to the 8250_pci driver, which tries to
probe it because it matched using the class entry.  The driver finds
that it is unable to automatically detect the correct settings to use,
so it returns -ENODEV.

You know that the information the driver needs is to match this card
using a device_data value of '7'.  So you echo 1234 5678 0 0 0 0 7
into new_id.

The kernel attempts to re-bind 8250_pci to this device.  However,
because it scans the PCI driver tables, it _again_ matches the class
entry which has the wrong device_data.  It fails.

End of story.  You can't support the card without rebuilding the
kernel (or writing a specific PCI probe module to support it.)

So, can we make new_id override the driver-internal PCI ID tables?
IOW, like this:

There was an off-by-one bug in bnx2_tx_avail().  If the tx ring is
completely full, the producer and consumer indices may be apart by
256 even though the ring size is only 255.  One entry in the ring is
unused and must be properly accounted for when calculating the number
of available entries.  The bug caused the tx ring entries to be
reused by mistake, overwriting active entries, and ultimately causing
it to crash.

This bug rarely occurs because the tx ring is rarely completely full.
We always stop when there is less than MAX_SKB_FRAGS entries available
in the ring.
