* UIO: Fix mapping of logical and virtual memoryAndrew G. Harvey2008-10-16
| | | | | | | | | | | | | | mmap() doesn't work as expected for UIO_MEM_LOGICAL or UIO_MEM_VIRTUAL mappings. The offset into the memory needs to be added, otherwise uio_vma_fault always returns the first page only. Note that for UIO userspace calls mmap() with offset = N * getpagesize() to access mapping N. This must be compensated when calculating the offset. A comment was added to explain this since it is not obvious. Signed-off-by: Andrew G. Harvey <agh@cisco.com> Signed-off-by: Hans J.

* UIO: add automata sercos3 pci card supportJohn Ogness2008-10-16
| | | | | | | | | | | | | | | | | | | Here is a new version of the patch to support the Automata Sercos III PCI card driver. I now check that the IRQ is enabled before accepting the interrupt. I still use a logical OR to store the enabled interrupts and I've added a second use of a logical OR when restoring the enabled interrupts. I added an explanation of why I do this in comments at the top of the source file. Since I use a logical OR, I also removed the extra checks if the Interrupt Enable Register and ier0_cache are 0.

* UIO: Change driver name of uio_pdrvHans J. Koch2008-10-16
| | | | | | | | | | | The generic UIO platform device driver should be given a unique driver ID and not just "uio". This is especially important since we now have a similar driver named uio_pdrv_genirq. Currently, there's no user of this driver in the mainline kernel. Signed-off-by: Hans J.

* UIO: Add alignment warnings for uio-memHans J. Koch2008-10-16

* Driver core: add bus_sort_breadthfirst() functionGreg Kroah-Hartman2008-10-16
| | | | | | | | | | | | The PCI core wants to reorder the devices in the bus list. So move this functionality out of the pci core and into the driver core so that anyone else can also do this if needed. This also lets us change how struct device is attached to drivers in the future without messing with the PCI core.

* kobject: Fix kobject_rename and !CONFIG_SYSFSEric W. Biederman2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When looking at kobject_rename I found two bugs with that exist when sysfs support is disabled in the kernel. kobject_rename does not change the name on the kobject when sysfs support is not compiled in. kobject_rename without locking attempts to check the validity of a rename operation, which the kobject layer simply does not have the infrastructure to do. This patch documents the previously unstated requirement of kobject_rename that is the responsibility of the caller to provide mutual exclusion and to be certain that the new_name for the kobject is valid. This patch modifies sysfs_rename_dir in !CONFIG_SYSFS case to call kobject_set_name to actually change the kobject_name. This patch removes the bogus and misleading check in kobject_rename that attempts to see if a rename is valid. The check is bogus because we do not have the proper locking. The check is misleading because it looks like we can and do perform checking at the kobject level that we don't. Signed-off-by: Eric W.

* usb: turn dev_warn+WARN_ON combos into dev_WARNArjan van de Ven2008-10-16

* debug: use dev_WARN() rather than WARN_ON() in device_pm_add()Arjan van de Ven2008-10-16
| | | | | | | | | | | | | | | device_pm_add() has a WARN_ON that is showing relatively high on kerneloops.org, but unfortunately the WARN_ON is less than useful in that it doesn't print any information about what device is causing the issue.

* device model: Do a quickcheck for driver binding before doing an expensive checkArjan van de Ven2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a quick check for the driver<->device match before taking the locks and doin gthe expensive checks. Taking the lock hurts in asynchronous boot context where the device lock gets hit; one of the init functions takes the lock and goes to do an expensive hardware init; the other init functions walk the same PCI list and get stuck on the lock as a result. For the common case, we can know there's no chance whatsoever of a match if the device isn't in the drivers ID table... so this patch does that check as a best-effort-avoid-the-lock approach. Bootcharts for before and after can be seen at http://www.fenrus.org/before.svg http://www.fenrus.org/after.svg Note the long time "agp_ali_init" takes in the first graph; my laptop doesn't even have an ALI chip in it! (the bootgraphs look a bit dissimilar, but that's the point, the first one has a bunch of arbitrary delays in it that cause it to look very different) This reduces my kernel boot time by about 20% Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
