* sched: fix SCHED_FAIR wake-idle logic errorGregory Haskins2008-05-05
| | | | | | | | | | | | | | | | | | | We currently use an optimization to skip the overhead of wake-idle processing if more than one task is assigned to a run-queue. The assumption is that the system must already be load-balanced or we wouldnt be overloaded to begin with. The problem is that we are looking at rq->nr_running, which may include RT tasks in addition to CFS tasks. Since the presence of RT tasks really has no bearing on the balance status of CFS tasks, this throws the calculation off. This patch changes the logic to only consider the number of CFS tasks when making the decision to optimze the wake-idle.

* sched: fix RT task-wakeup logicGregory Haskins2008-05-05
| | | | | | | | | | | | | | | | | | | Dmitry Adamushko pointed out a logic error in task_wake_up_rt() where we will always evaluate to "true". You can find the thread here: http://lkml.org/lkml/2008/4/22/296 In reality, we only want to try to push tasks away when a wake up request is not going to preempt the current task. So lets fix it. Note: We introduce test_tsk_need_resched() instead of open-coding the flag check so that the merge-conflict with -rt should help remind us that we may need to support NEEDS_RESCHED_DELAYED in the future, too.

| * kgdb: 1000 loops for the single step test in kgdbtsJason Wessel2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | The single step test is not terribly costly and it should be able to pass at 1000 loops successfully in under 1 second. A non-kgdb timing regression was found using this test, but it did not occur frequently because by default the test was only executed a single time. This patch changes the default for the single step test to 1000 iterations and allows for individual configuration of the single step test to further exercise the kgdb subsystem when needed.

A patch for some versions of the OptiPlex was proposed here -- http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and later kernels, according to http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However, the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex machines have a DMI_BOARD_NAME of "0RF703". I therefore suggest adding another clause to reboot.c, similar to the one in the original patch, but matching a DMI_BOARD_NAME of "0RF703". On further inspection, it seems that there are other DMI_BOARD_NAMEs for this same machine. They seem to change from time to time, which means that the current code is fragile. Moreover, using bios reboot should not break non-SFF OptiPlex 745s, and so a reasonable fix is to simply drop the match on DMI_BOARD_NAME.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch/x86/pci/Makefile_32 has a nasty detail. VISWS and NUMAQ build override the generic pci-y rules. This needs a proper cleanup, but that needs more thoughts. Undo commit 895d30935ebe05f192e844792668bf8d19deaae7 x86: numaq fix do not override the existing pci-y rule when adding visws or numaq rules. There is also a stupid init function ordering problem vs. acpi.o Add comments to the Makefile to avoid tripping over this again.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all device types need a wildcard at the end of their module aliases. In particular, for i2c module aliases, the trailing wildcard is not only unneeded, it could also cause the wrong driver to be loaded. As I2C devices have no IDs, i2c module aliases are simple, arbitrary device names. For example: $ /sbin/modinfo lm90 filename: /lib/modules/2.6.25-git18/kernel/drivers/hwmon/lm90.ko author: Jean Delvare <khali@linux-fr.org> description: LM90/ADM1032 driver license: GPL vermagic: 2.6.25-git18 mod_unload depends: hwmon alias: i2c:lm90* alias: i2c:adm1032* alias: i2c:lm99* alias: i2c:lm86* alias: i2c:max6657* alias: i2c:adt7461* alias: i2c:max6680* $ This would cause trouble if one I2C chip name matches the beginning of another I2C chip name and both chips are supported by different drivers. For example, an i2c device named lm9042 would cause the lm90 driver to be loaded, while it doesn't support that device. This case has yet to be seen in practice, but still, I'd like to fix it now. The cleanest fix is to remove the trailing wildcard from i2c module aliases. Here's a patch doing this. Not all device type aliases need a trailing wildcard, in particular the i2c aliases don't. Don't add a wildcard by default in do_table(), instead let each device type handler add it if needed. I have tested types acpi, dmi, eisa, i2c, ide, ieee1394, input, pci, pcmcia, platform, pnp, scsi, serio, ssb and usb. Other types (ccw, of, vio, parisc, sdio and virtio) are untested.
