2009-01-09md: use sysfs_notify_dirent to notify changes to md/sync_action.NeilBrown1-0/+1
There is no compelling need for this, but sysfs_notify_dirent is a nicer interface and the change is good for consistency. Signed-off-by: NeilBrown <neilb@suse.de>

2009-01-07PCI hotplug: introduce functions for ACPI slot detectionKenji Kaneshige2-0/+11
Some ACPI related PCI hotplug code can be shared among PCI hotplug drivers. This patch introduces the following functions in drivers/pci/hotplug/acpi_pcihp.c to share the code, and changes acpiphp and pciehp to use them. - int acpi_pci_detect_ejectable(struct pci_bus *pbus) This checks if the specified PCI bus has ejectable slots. - int acpi_pci_check_ejectable(struct pci_bus *pbus, acpi_handle handle) This checks if the specified handle is ejectable ACPI PCI slot. The 'pbus' parameter is needed to check if 'handle' is PCI related ACPI object. This patch also introduces the following inline function in include/linux/pci-acpi.h, which is useful to get ACPI handle of the PCI bridge from struct pci_bus of the bridge's secondary bus. - static inline acpi_handle acpi_pci_get_bridge_handle(struct pci_bus *pbus) This returns ACPI handle of the PCI bridge which generates PCI bus specified by 'pbus'.

2009-01-07resource: allow MMIO exclusivity for device driversArjan van de Ven2-3/+11
Device drivers that use pci_request_regions() (and similar APIs) have a reasonable expectation that they are the only ones accessing their device. As part of the e1000e hunt, we were afraid that some userland (X or some bootsplash stuff) was mapping the MMIO region that the driver thought it had exclusively via /dev/mem or via various sysfs resource mappings. This patch adds the option for device drivers to cause their reserved regions to the "banned from /dev/mem use" list, so now both kernel memory and device-exclusive MMIO regions are banned. NOTE: This is only active when CONFIG_STRICT_DEVMEM is set. In addition to the config option, a kernel parameter iomem=relaxed is provided for the cases where developers want to diagnose, in the field, drivers issues from userspace.

2009-01-07USB: storage: add last-sector hacksAlan Stern1-2/+4
This patch (as1189b) adds some hacks to usb-storage for dealing with the growing problems involving bad capacity values and last-sector accesses: A new flag, US_FL_CAPACITY_OK, is created to indicate that the device is known to report its capacity correctly. An unusual_devs entry for Linux's own File-backed Storage Gadget is added with this flag set, since g_file_storage always reports the correct capacity and since the capacity need not be even (it is determined by the size of the backing file). An entry in unusual_devs.h which has only the CAPACITY_OK flag set shouldn't prejudice libusual, since the device will work perfectly well with either usb-storage or ub. So a new macro, COMPLIANT_DEV, is added to let libusual know about these entries. When a last-sector access succeeds and the total number of sectors is odd (the unexpected case, in which guessing that the number is even might cause trouble), a WARN is triggered. The kerneloops.org project will collect these warnings, allowing us to add CAPACITY_OK flags for the devices in question before implementing the default-to-even heuristic. If users want to prevent the stack dump produced by the WARN, they can disable the hack by adding an unusual_devs entry for their device with the CAPACITY_OK flag. When a last-sector access fails three times in a row and neither the FIX_CAPACITY nor the CAPACITY_OK flag is set, we assume the last-sector bug is present. We replace the existing status and sense data with values that will cause the SCSI core to fail the access immediately rather than retry indefinitely. This should fix the difficulties people have been having with Nokia phones.

2009-01-07USB: utilize the bus notifiersAlan Stern1-0/+2
This patch (as1185) makes usbcore take advantage of the bus notifications sent out by the driver core. Now we can create all our device and interface attribute files before the device or interface uevent is broadcast. A side effect is that we no longer create the endpoint "pseudo" devices at the same time as a device or interface is registered -- it seems like a bad idea to try registering an endpoint before the registration of its parent is complete. So the routines for creating and removing endpoint devices have been split out and renamed, and they are called explicitly when needed. A new bitflag is used for keeping track of whether or not the interface's endpoint devices have been created, since (just as with the interface attributes) they vary with the altsetting and hence can be changed at random times.

2009-01-07USB: Enhance usage of pm_message_tAlan Stern1-1/+1
This patch (as1177) modifies the USB core suspend and resume routines. The resume functions now will take a pm_message_t argument, so they will know what sort of resume is occurring. The new argument is also passed to the port suspend/resume and bus suspend/resume routines (although they don't use it for anything but debugging). In addition, special pm_message_t values are used for user-initiated, device-initiated (i.e., remote wakeup), and automatic suspend/resume. By testing these values, drivers can tell whether or not a particular suspend was an autosuspend. Unfortunately, they can't do the same for resumes -- not until the pm_message_t argument is also passed to the drivers' resume methods. That will require a bigger change. IMO, the whole Power Management framework should have been set up this way in the first place. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-01-07USB: otg: add otg_put_transceiver()Philipp Zabel1-0/+1
As Russell King points out, calling put_device(otg_transceiver->dev) directly in driver cleanup paths makes assumptions about otg_transceiver internals.

2009-01-07USB: otg: gpio_vbus transceiver stubPhilipp Zabel1-0/+30
gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.

2009-01-07USB: storage devices and SATBen Efros1-2/+3
Add the SANE SENSE flag to indicate that a device is capable of handling more than 18-bytes of sense data. This functionality is required for USB-ATA bridges implementing SAT. A future patch will actually enable this function for several devices. The logic behind this is that we can detect support for SANE_SENSE in a few ways: 1) ATA PASS THROUGH (12) or (16) execute successfully 2) SPC-3 or higher is in use 3) A previous CHECK CONDITION occurred with sense format 70-73 and had a length greater than 18-bytes total Signed-off-by: Ben Efros <ben@pc-doctor.com> Signed-off-by: Matthew Dharm <mdharm-usb@one-eyed-alien.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-01-07USB: Allow usbmon as a module even if usbcore is builtinPete Zaitcev1-1/+1
usbmon can only be built as a module if usbcore is a module too. Trivial changes to the relevant Kconfig and Makefile (and a few trivial changes elsewhere) allow usbmon to be built as a module even if usbcore is builtin. This is verified to work in all 9 permutations (3 correctly prohibited by Kconfig, 6 build a suitable result).
