2009-10-12perf tools: Fix counter sample frequency breakageMike Galbraith
Commit 42e59d7d19dc4b4 switched to a default sample frequency of 1KHz, which overrides any user supplied count, causing sched, top and timechart to miss events due to their discrete events being flagged PERF_SAMPLE_PERIOD.

As reported in http://bugzilla.kernel.org/show_bug.cgi?id=13940 on some system when acpi are enabled, acpi clears some BAR for some devices without reason, and kernel will need to allocate devices for them. It then apparently hits some undocumented resource conflict, resulting in non-working devices. Try to increase alignment to get more safe range for unassigned devices.

2009-10-09USB: ehci: Fix isoc scheduling boundary checking.Sarah Sharp
The EHCI driver does some bounds checking when it's scheduling an iTD for an active endpoint. It sets the local variable start to stream->next_uframe and moves that variable further in the schedule if necessary. However, the driver fails to do anything with start before jumping to the ready label and setting the URB's starting frame to stream->next_uframe. Alan Stern confirms the EHCI driver should set stream->next_uframe to start before jumping.

2009-10-09USB: storage: When a device returns no sense data, call it a Hardware ErrorAlan Stern
This patch (as1294) fixes a problem that has plagued users for several kernel releases. Some USB mass-storage devices don't return any sense data when they encounter certain kinds of errors. The SCSI layer interprets this to mean that the operation should be retried, and the same thing happens -- over and over again with no limit. In some circumstances (such as when a bus reset occurs) that is the right thing to do, but not here. The patch checks for this condition (a transport failure with no sense data) and changes the result code to DID_ERROR and the sense code to Hardware Error. This does get only a limited number of retries, and so the command will fail relatively quickly instead of getting stuck in an infinite loop. This fixes a large part of Bugzilla #14118.

2009-10-09USB: xhci: Don't wait for a disable slot cmd when HC dies.Sarah Sharp
When the host controller dies or is removed while a device is plugged in, the USB core will attempt to deallocate the struct usb_device. That will call into xhci_free_dev(). This function used to attempt to submit a disable slot command to the host controller and clean up the device structures when that command returned. Change xhci_free_dev() to skip the command submission and just free the memory if the host controller died.

2009-10-09USB: xhci: Handle canceled URBs when HC dies.Sarah Sharp
When the host controller dies (e.g. it is removed from a PCI card slot), the xHCI driver cannot expect commands to complete. The buggy code this patch fixes would mark an URB as canceled and then expect the URB to be completed when the stop endpoint command completed. That would never happen if the host controller was dead, so the USB core would just hang in the disconnect code. If the host controller died, and the driver asks to cancel an URB, free any structures associated with that URB and immediately give it back.

2009-10-09USB: ftdi_sio: re-implement read processingJohan Hovold
- Re-structure read processing. - Kill obsolete work queue and always push to tty in completion handler. - Use tty_insert_flip_string instead of per character push when possible. - Fix stalled-read regression in 2.6.31 by using urb status to determine when port is closed rather than port count. - Fix race with open/close by checking ASYNCB_INITIALIZED in unthrottle. - Kill private rx_flag and lock and use throttle flags in usb_serial_port instead.

2009-10-09USB: ftdi_sio: clean up read completion handlerJohan Hovold
Remove superfluous error checks in completion handler: - No need to check private data and urb pointers as we check urb-status before dereferencing priv (which is not freed until urb has been killed on close). - No need to check tty as it is checked again when processing. - No need to check urb->number_of_packets on bulk urb. Note that both private data and tty are checked again before processing (possibly from work queue which also is cancelled on close).

2009-10-09Staging: comedi: fix build on arches that don't want comedi driversGreg Kroah-Hartman
This should fix the problem of comedi drivers showing up on arches that can not support the comedi subsystem (like s390).
