2006-12-20PCI: Use pci_find_ht_capability() in drivers/pci/quirks.cMichael Ellerman
Use pci_find_ht_capability() in drivers/pci/quirks.c. I'm pretty sure the logic is unchanged here, but someone please eye-ball it for me. I've changed the message to be a little shorter, it's now: PCI: Found (enabled|disabled) HT MSI mapping on xxxx:xx:xx.x Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-12-20PCI: Add pci_find_ht_capability() for finding Hypertransport capabilitiesMichael Ellerman
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.

2006-12-20PCI: Create __pci_bus_find_cap_start() from __pci_bus_find_cap()Michael Ellerman
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.

2006-12-20pci: Introduce pci_find_presentAlan Cox
This works like pci_dev_present but instead of returning boolean returns the matching pci_device_id entry. This makes it much more useful.

2006-12-20PCI: use /sys/bus/pci/drivers/<driver>/new_id firstRussell King
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: From: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-12-17[BNX2]: Fix panic in bnx2_tx_int().Michael Chan
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.

2006-12-15[S390] Fix reboot hang on LPARsMichael Holzheu
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.
