2009-01-07topology: Fix sparc64 build.David Miller
Due to changeset ba84be2338d3a2b6020d39279335bb06fcd332e1 ("remove linux/hardirq.h from asm-generic/local.h") the sparc64 build started failing on drivers/base/topology.c: drivers/base/topology.c: In function ‘show_physical_package_id’: drivers/base/topology.c:103: error: implicit declaration of function ‘cpu_data’ drivers/base/topology.c:103: error: request for member ‘proc_id’ in something not a structure or union drivers/base/topology.c: In function ‘show_core_id’: drivers/base/topology.c:106: error: request for member ‘core_id’ in something not a structure or union Adding the obvious fix of including asm/cpudata.h into asm/topology.h on sparc64 doesn't fix it, in fact it makes things worse because of the header file dependency chain: linux/gfp.h --> linux/mmzone.h --> linux/topology.h --> asm/topology.h --> asm/cpudata.h --> linux/percpu.h --> linux/slab.h which results in: include/linux/slub_def.h: In function ‘kmalloc_large’: include/linux/slub_def.h:209: error: implicit declaration of function ‘__get_free_pages’ include/linux/slub_def.h:209: error: ‘__GFP_COMP’ undeclared (first use in this function) include/linux/slub_def.h:209: error: (Each undeclared identifier is reported only once include/linux/slub_def.h:209: error: for each function it appears in.) include/linux/slub_def.h:209: warning: cast to pointer from integer of different size The simplest thing to do is to add yet another one-off hack like parts of the guilty changeset did, by putting an explicit linux/hardirq.h include into drivers/base/topology.c Signed-off-by: David S.

2009-01-07i2400m/SDIO: TX and RX path backendsInaky Perez-Gonzalez
Implements the backend so that the generic driver can TX/RX to/from the SDIO device. For RX, when data is ready the SDIO IRQ is fired and that will allocate an skb, put all the data there and then pass it to the generic driver RX code for processing and delivery. TX, when kicked by the generic driver, will schedule work on a driver-specific workqueue that pulls data from the TX FIFO and sends it to the device until it drains it. Thread contexts are needed as SDIO functions are blocking. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-01-07i2400m/USB: TX and RX path backendsInaky Perez-Gonzalez
Implements the backend so that the generic driver can TX/RX to/from the USB device. TX is implemented with a kthread sitting in a never-ending loop that when kicked by the generic driver's TX code will pull data from the TX FIFO and send it to the device until it drains it. Then it goes back sleep, waiting for another kick. RX is implemented in a similar fashion, but reads are kicked in by the device notifying in the interrupt endpoint that data is ready. Device reset notifications are also sent via the notification endpoint. We need a thread contexts to run USB autopm functions (blocking) and to process the received data (can get to be heavy in processing time).

2009-01-07i2400m: RX and TX data/control pathsInaky Perez-Gonzalez
Handling of TX/RX data to/from the i2400m device (IP packets, control and diagnostics). On RX, this parses the received read transaction from the device, breaks it in chunks and passes it to the corresponding subsystems (network and control). Transmission to the device is done through a software FIFO, as data/control frames can be coalesced (while the device is reading the previous tx transaction, others accumulate). A FIFO is used because at the end it is resource-cheaper that scatter/gather over USB. As well, most traffic is going to be download (vs upload).

2009-01-07i2400m: firmware loading and bootrom initializationInaky Perez-Gonzalez

The most critical thing in here is the piece that puts the device in boot-mode from any other (undetermined) state, otherwise, it is just pushing the bytes from the firmware file to the device.

2009-01-07i2400m: linkage to the networking stackInaky Perez-Gonzalez
Implementation of the glue to the network stack so the WiMAX device shows up as an Ethernet device. Initially we shot for implementing a Pure IP device -- however, the world seems to turn around Ethernet devices. Main issues were with the ISC DHCP client and servers (as they don't understand types other than Ethernet and Token Ring). We proceeded to register with IANA the PureIP hw type, so that DHCP requests could declare such. We also created patches to the main ISC DHCP versions to support it. However, until all that permeates into deployments, there is going to be a long time. So we moved back to wrap Ethernet frames around the PureIP device. At the time being this has overhead; we need to reallocate with space for an Ethernet header. The reason is the device-to-host protocol coalesces many network packets into a single message, so we can't introduce Ethernet headers without overwriting valid data from other packets. Coming-soon versions of the firmware have this issue solved. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-01-07USB: re-enable interface after driver unbindsAlan Stern
This patch (as1197) fixes an error introduced recently. Since a significant number of devices can't handle Set-Interface requests, we no longer call usb_set_interface() when a driver unbinds from an interface, provided the interface is already in altsetting 0. However the interface still does get disabled, and the call to usb_set_interface() was the only thing re-enabling it. Since the interface doesn't get re-enabled, further attempts to use it fail. So the patch adds a call to usb_enable_interface() when a driver unbinds and the interface is in altsetting 0. For this to work right, the interface's endpoints have to be re-enabled but their toggles have to be left alone. Therefore an additional argument is added to usb_enable_endpoint() and usb_enable_interface(), a flag indicating whether or not the endpoint toggles should be reset. This is a forward-ported version of a patch which fixes Bugzilla #12301.

2009-01-07USB: cancel pending Set-Config requests if userspace gets there firstAlan Stern
This patch (as1195) eliminates a potential problem identified by Oliver Neukum. When a driver queues an asynchronous Set-Config request using usb_driver_set_configuration(), the request should be cancelled if userspace changes the configuration first. The patch introduces a linked list of pending async Set-Config requests, and uses it to invalidate the requests for a particular device whenever that device's configuration is set.

2009-01-07USB: automatically enable wakeup for PCI host controllersAlan Stern
This patch (as1193b) enables wakeup during initialization for all PCI host controllers, and it removes some code (and comments!) that are no longer needed now that the PCI core automatically initializes wakeup settings for all new devices. The idea is that the bus should initialize wakeup, and the bus glue or controller driver should enable it.

2009-01-07USB: fix up suspend and resume for PCI host controllersAlan Stern
This patch (as1192) rearranges the USB PCI host controller suspend and resume and resume routines: Use pci_wake_from_d3() for enabling and disabling wakeup, instead of pci_enable_wake(). Carry out the actual state change while interrupts are disabled. Change the order of the preparations to agree with the general recommendation for PCI devices, instead of messing around with the wakeup settings while the device is in D3. In .suspend: Call the underlying driver to disable IRQ generation; pci_wake_from_d3(device_may_wakeup()); pci_disable_device(); In .suspend_late: pci_save_state(); pci_set_power_state(D3hot); (for PPC_PMAC) Disable ASIC clocks In .resume_early: (for PPC_PMAC) Enable ASIC clocks pci_set_power_state(D0); pci_restore_state(); In .resume: pci_enable_device(); pci_set_master(); pci_wake_from_d3(0); Call the underlying driver to reenable IRQ generation Add the necessary .suspend_late and .resume_early method pointers to the PCI host controller drivers.

2009-01-07USB: storage: set CAPACITY_HEURISTICS flag for bad vendorsAlan Stern
This patch (as1194) makes usb-storage set the CAPACITY_HEURISTICS flag for all devices made by Nokia, Nikon, or Motorola. These companies seem to include the READ CAPACITY bug in all of their devices. Since cell phones and digital cameras rely on flash storage, which always has an even number of sectors, setting CAPACITY_HEURISTICS shouldn't cause any problems. Not even if the companies wise up and start making devices without the bug. A large number of unusual_devs entries are now unnecessary, so the patch removes them.

2009-01-07USB: storage: make the "quirks=" module parameter writableAlan Stern

2009-01-07USB: storage: add last-sector hacksAlan Stern
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: unusual dev for Option N.V. ZeroCD modemsDan Williams
Many newer Option mobile broadband devices initially provide a usb-storage "driver CD" device that's pretty useless on Linux since any software on it most likely wouldn't be compatible with your kernel or distro anyway. Thus, by default just kill the driver CD device by sending the SCSI 'rezero' command, but allow override of the default behavior via usb-storage module parameter so users can keep the ZeroCD device if they really want to.

2009-01-07USB: utilize the bus notifiersAlan Stern
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.
