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.

This works like pci_dev_present but instead of returning boolean returns
the matching pci_device_id entry. This makes it much more useful. Code
bloat is basically nil as the old boolean function is rewritten in terms of
the new one.

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

Reboot hangs on LPARs without diag308 support. The reason for this is,
that before the reboot is done, the channel subsystem is shut down.
During the reset on each possible subchannel a "store subchannel" is
done. This operation can end in a program check interruption, if the
specified subchannel set is not implemented by the hardware. During
the reset, currently we do not have a program check handler, which
leads to the described kernel bug. We install now a new program check
handler for the reboot code to fix this problem.

The JC14xx are RS422/RS485-based cards, but in order for these to be
