2007-02-04IB: Return qp pointer as part of ib_wcMichael S. Tsirkin
struct ib_wc currently only includes the local QP number: this matches the IB spec, but seems mostly useless. The following patch replaces this with the pointer to qp itself, and updates all low level drivers and all users. This has the following advantages: - Ability to get a per-qp context through wc->qp->qp_context - Existing drivers already have the qp pointer ready in poll cq, so this change actually saves a tiny bit (extra memory read) on data path (for ehca it would actually be expensive to find the QP pointer when polling a CQ, but ehca does not support SRQ so we can leave wc->qp as NULL for ehca) - Users that need the QP number can still get it through wc->qp->qp_num Use case: In IPoIB connected mode code, I have a common CQ shared by multiple QPs. To track connection usage, I need a way to get at some per-QP context upon the completion, and I would like to avoid allocating context object per work request just to stick a QP pointer into it. With this code, I can just use wc->qp->qp_context. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-02-02[SCSI] sd: udev accessing an uninitialized scsi_disk field results in a crashNagendra Singh Tomar
sd_probe() calls class_device_add() even before initializing the sdkp->device variable. class_device_add() eventually results in the user mode udev program to be called. udev program can read the the allow_restart attribute of the newly created scsi device. This is resulting in a crash as the show function for allow_restart (i.e sd_show_allow_restart) returns the attribute value by reading the sdkp->device->allow_restart variable. As the sdkp->device is not initialized before calling the user mode hotplug helper, this results in a crash. The patch below solves it by calling class_device_add() only after the necessary fields in the scsi_disk structure are initialized properly.

2007-02-02ahci/pata_jmicron: fix JMicron quirkTejun Heo
For all JMicrons except for 361 and 368, AHCI mode enable bits in the Control(1) should be set. This used to be done in both ahci and pata_jmicron but while moving programming to PCI quirk, it was removed from ahci part while still left in pata_jmicron. The implemented JMicron PCI quirk was incorrect in that it didn't program AHCI mode enable bits. If pata_jmicron is loaded first and programs those bits, the ahci ports work; otherwise, ahci device detection fails miserably. This patch makes JMicron PCI quirk clear SATA IDE mode bits and set AHCI mode bits and remove the respective part from pata_jmicron. Tested on JMB361, 363 and 368.

2007-01-30[PATCH] Fix VIA quirksJean Delvare
Fix VIA quirks that were recently broken by Alan Cox in the upstream kernel (commit 1597cacbe39802d86656d1f2e6329895bd2ef531). My understanding is that pci_find_present() doesn't work yet at the time the quirks are run. So I used a two-step quirk as is done for some other quirks already. First we detect the VIA south bridges and set the right low and high device limits, then we are ready to actually run the quirks on the affected devices.

This reverts commit 0c0b3ae68ec93b1db5c637d294647d1cca0df763. Quoth David: "Jeff, please revert It's wrong. We had a lengthy analysis of this piece of code several months ago, and it is correct. Consider, if we run the loop and we get an error the following happens: 1) attempt of ifb_init_one(i) fails, therefore we should not try to "ifb_free_one()" on "i" since it failed 2) the loop iteration first increments "i", then it check for error Therefore we must decrement "i" twice before the first free during the cleanup. One to "undo" the for() loop increment, and one to "skip" the ifb_init_one() case which failed."

This fixes the issue of frequent link changes under heavy traffic reported below: http://bugzilla.kernel.org/show_bug.cgi?id=7696 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=216338 The b44 chip occasionally needs to be reset when ISTAT_ERRORS are encountered. The reset sequence includes a PHY reset that will take many seconds to complete and cause the link to go down and up. By skipping the PHY reset, it will greatly reduce the interruption when ISTAT_ERRORS are encountered. Change the full_reset parameter to reset_kind parameter in b44_init_hw(). This will allow PHY reset to be skipped when ISTAT_ERRORS are encountered.

2007-01-30libata: fix translation for START STOP UNITRobert Hancock
libata's SCSI translation for the SCSI START STOP UNIT command with the START bit clear (i.e. stopping the drive) appears to be incorrect. It sends an ATA STANDBY command with the time period set to 0, which the code comment says means "now", but the ATA standard says this means disable the standby timer, which effectively does nothing. Change this to issue a STANDBY IMMEDIATE command which will actually spin the drive down. The SAT (SCSI/ATA Translation) standard revision 9 concurs with this choice.
