Major cleanup of all s390 inline assemblies. They now have a common coding style. Quite a few have been shortened, mainly by using register asm variables. Use of the EX_TABLE macro helps as well. The atomic ops, bit ops and locking inlines new use the Q-constraint if a newer gcc is used. That results in slightly better code. Thanks to Christian Borntraeger for proof reading the changes.

A user space program can read uninitialised kernel memory by appending to a file from a bad address and then reading the result back. The cause is the copy_from_user function that does not clear the remaining bytes of the kernel buffer after it got a fault on the user space address. Signed-off-by: -

The clocksource infrastructure introduced with commit ad596171 broke 31 bit s390. The reason is that the do_div() primitive for 31 bit always had a restriction: it could only divide an unsigned 64 bit integer by an unsigned 31 bit integer. The clocksource code now uses do_div() with a base value that has the most significant bit set. The result is that clock->cycle_interval has a funny value which causes the linux time to jump around like mad. The solution is "obvious": implement a proper __div64_32 function for 31 bit s390.

Adapted from an earlier patch by Greg KH <gregkh@suse.de>. That patch added multiple read urbs and larger transfer buffers to allow data transfers at full EvDO speed. This version includes additional device IDs and fixes a memory leak in the transfer buffer allocation. Some (maybe all?) of the supported devices present multiple bulk endpoints, the additional EPs can be used for control and status functions, This version allocates 3 EPs by default, that can be changed using the 'endpoints' module parameter. Tested with Sierra Wireless EM5625 and MC5720 embedded modules. Device ID (0x0c88, 0x17da) for the Kyocera Wireless KPC650/Passport was added but is not yet tested.

This revamps handling of the hardware "async advance" IRQ, and its watchdog timer. Basically it dis-entangles that important timeout from the others, simplifying the associated state and code to make it more robust. This reportedly improves behavior of EHCI on some systems with VIA chips, and AFAIK won't affect non-VIA hardware. VIA systems need this code to recover from silcon bugs whereby the "async advance" IRQ isn't issued. Signed-off-by:

This patch(as785) forces the PM core to resume a root hub after a power loss during system sleep. If the root hub had been suspended before the system sleep then normally the PM core would not resume it afterward. Without this resume, various sorts of wakeup events (like port change events) can get lost. Signed-off-by:

When ohci-hcd is shutting down (for rmmod or PC-card removal), there is a window when the device is shut down, HC communication area (->hcca) is freed, but the core has not called "free_irq" yet. If another device triggers a shared interrupt in this window, we oops when trying to access the freed ->hcca. This patch removes the window by calling free_irq before ->hcca is freed. The patch is tested at the PC hotplug test rig at Stratus, and with rmmod by Rafael Wysocki. Signed-off-by:

The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages. Signed-off-by:

This "u132-hcd" module is one half of the "driver" for ELAN's U132 which is a USB to CardBus OHCI controller adapter. This module needs the "ftdi-elan" module in order to communicate to CardBus OHCI controller inserted into the U132 adapter. When the "ftdi-elan" module detects a supported CardBus OHCI controller in the U132 adapter it loads this "u132-hcd" module. Upon a successful device probe() the single workqueue is started up which does all the processing of commands from the USB core that implement the host controller. The workqueue maintains the urb queues and issues commands via the functions exported by the "ftdi-elan" module. Each such command will result in a callback. Note that the "ftdi-elan" module is a USB client driver. Note that this "u132-hcd" module is a (cut-down OHCI) host controller. Thus we have a topology with the parent of a host controller being a USB client! This really stresses the USB subsystem semaphore/mutex handling in the module removal. Signed-off-by:

This "ftdi-elan" module is one half of the "driver" for ELAN's Uxxx series adapters which are USB to PCMCIA CardBus adapters. Currently only the U132 adapter is available and it's module is called "u132-hcd". When the USB hot plug subsystem detects a Uxxx series adapter it should load this module. Upon a successful device probe() the jtag device file interface is created and the status workqueue started up. The jtag device file interface exists for the purpose of updating the firmware in the Uxxx series adapter, but as yet it had never been used. The status workqueue initializes the Uxxx and then sits there polling the Uxxx until a supported PCMCIA CardBus device is detected it will start the command and respond workqueues and then load the module that handles the device. This will initially be only the u132-hcd module. The status workqueue then just polls the Uxxx looking for card ejects. The command and respond workqueues implement a command sequencer for communicating with the firmware on the other side of the FTDI chip in the Uxxx. This "ftdi-elan" module exports some functions to interface with the sequencer. Note that this module is a USB client driver. Note that the "u132-hcd" module is a (cut-down OHCI) host controller. Thus we have a topology with the parent of a host controller being a USB client! This really stresses the USB subsystem semaphore/mutex handling in the module removal. Signed-off-by:

When receiving a fatal error from the USB core, e.g. EILSEQ (which can happen if the polling interval is too short), fail gracefully. Previously the driver would fill the log with useless error messages or (more alarmingly) silently spin forever trying to write updated control information to the device. This change implements a new flag which if cleared indicates that the driver has failed. The flag will be set on initialization, cleared on fatal errors, and anything else that touches the USB port in the driver will abort if the flag is clear. When the flag is cleared, a message will be logged indicating that the driver has failed. Signed-off-by:

Fix usb core function error return checks to look for negative errno values, not positive errno values. This bug had rendered those checks useless. Also remove attempted error recovery on control endpoints for EPIPE - with control endpoints EPIPE does not indicate a halted endpoint so trying to recover with usb_clear_halt() is not the correct action.

Rather than directly filling in URB fields, it's safer to use usb_fill_int_urb(). This improves robustness of the driver; URB changes in the future will not go uninitialized here. That point not withstanding, this driver should at least be self-consistent. Either use usb_fill_int_urb() everywhere or don't bother with it all. Signed-off-by:

The polling interval for the device can't always be 1msec. If it is too quick, the device can fail causing a fatal (to the driver) EILSEQ error from the USB core. The actual correct value is reported by the device as part of its configuration data, so use that value as the default. On a DeLorme Earthmate for example, the device reports that it wants a 6msec interval. As part of this fix, the "interval" module option has been fixed as well; the device's default can be overridden by specifying interval=<value> as a module option. Signed-off-by:
