2007-02-05e1000: fix NAPI performance on 4-port adaptersJesse Brandeburg
This fix attempts to solve a customer (IBM) reported issue with NAPI enabled e1000 having bad performance when transmitting simultaneously on four ports. The issue comes down to an interaction between NAPI, hardware interrupt balancing, and the driver rescheduling poll on the same processor. Try to fix by allowing the driver to re-enable interrupts sooner instead of polling one more time, when there was recently all the work completed in cleanup.

2007-02-05e1000: Fix MSI only interrupt handler routineJesse Brandeburg
Unfortunately the read-free MSI interrupt handler needs to flush write the icr register and thus we can't be read-free. Our MSI irq routine thus becomes a lot more simpler since we don't need to track link state anymore.

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.

Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the Help message. It was previously done via X, but X is already used for Xmon on ppc & powerpc platforms and this collision needs to be avoided. All callers of register_sysrq_key() are now marked in the sysrq op/key table. I didn't mark 'h' as Help because Help is just printed for any unknown key, such as '?'.

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."
