2007-07-19USB: documentation update for usb_unlink_urbAlan Stern
This patch (as936) updates the kerneldoc for usb_unlink_urb. The explanation of how endpoint queues are meant to work is now clearer and in better agreement with reality. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-19UHCI: short control URBs get a status stageAlan Stern
It has recently been pointed out that short control transfers should have a status stage, even if they generate an error because URB_SHORT_NOT_OK was set. This patch (as935) changes uhci-hcd to enable the status stage when this happens. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-19USB: mos7720, mos7840: remove redundant urb checkFlorin Malita
Coverity (1709, 1710, 1711, 1712, 1713) actually flagged these as REVERSE_INULLs (NULL check performed after dereference). But looking at the other drivers I can't see any similar tests and the USB core already makes sure urb is non-null - so might as well get rid of the checks.

2007-07-19USB: fix warning caused by autosuspend counter going negativeAlan Stern
This patch (as937) fixes a minor bug in the autosuspend usage-counting code. Each hub's usage counter keeps track of the number of unsuspended children. However the current driver increments the counter after registering a new child, by which time the child may already have been suspended and caused the counter to go negative. The obvious solution is to increment the counter before registering the child.

2007-07-19USB: add "descriptors" binary sysfs attributeAlan Stern
This patch (as934) adds a new readonly binary sysfs attribute file called "descriptors" for each USB device. The attribute contains the device descriptor followed by the raw descriptor entry (config plug subsidiary descriptors) for the current configuration. Having this information available in fixed-format binary makes life a lot easier for user programs by avoiding the need to open, read, and parse multiple sysfs text files. The information in this attribute file is much like that in usbfs's device file, but there are some significant differences: The 2-byte fields in the device descriptor are left in little-endian byte order, as they appear on the bus and in the kernel. Only one raw descriptor set is presented, that of the current configuration. Opening this file will not cause a suspended device to be autoresumed. The last item in particular should be a big selling point for libusb, which currently forces all USB devices to be resumed as it scans the device tree.

2007-07-19isp116x-hcd: prepare for urb->statusAlan Stern
This patch (as931b), adapted from a patch by Olav Kongas, makes a small set of conservative changes to the isp116x-hcd driver in preparation for the removal of urb->status. finish_request() is moved up in the source and is called as soon as the URB is known to have completed, rather than after all the active endpoints have been scanned. The status of a completed URB is kept in a local variable and copied to urb->status only when the URB is about to be given back. -EREMOTEIO error status for control transfers is set after the status stage rather than when the short packet arrives. Some unnecessary uses of urb->lock are removed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: Olav Kongas <ok@artecdesign.ee> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-19USB: usblp: "Big cleanup" breaks O_NONBLOCKPete Zaitcev
I found the first regresson in the rewritten ("all dynamic" and "no races") driver. If application uses O_NONBLOCK, I return -EAGAIN despite the URB being submitted successfuly. This causes the application to resubmit the same data erroneously. The fix is to pretend that the transfer has succeeded even if URB was merely queued. It is the same behaviour as with the old version. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-07-20ide: add support for SCSI ioctls to ide-floppyBartlomiej Zolnierkiewicz
Now that ide-floppy supports SG_IO we can add support for SCSI ioctls (except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET ones - we can add them later iff really needed). While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from generic_ide_ioctl(): - This prevents ide-{disk,tape,scsi} device drivers from obtaining REQ_TYPE_BLOCK_PC type requests which are currently unsupported by these drivers and which are potentially harmful (as reported by Andrew). - There is no functionality loss since aforementioned ioctls will now be handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl() (for devices using ide-cd driver).

This fixes PIO fallback in siimage_config_drive_for_dma() to use max PIO mode available instead of PIO4 (config_siimage_chipset_for_pio() used wrong arguments for ide_get_best_pio_mode() and as a results always tried to set PIO4). * Remove no longer needed siimage_taskfile_timing() and config_siimage_chipset_for_pio(). * Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes from siimage_speedproc() * Bump driver version. v2: * Fix issues noticed by Sergei: - correct pair device check - trim only taskfile PIO to the slowest of the master/slave - enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes from siimage_speedproc() - add TODO item for IORDY bugs - minor cleanups Reviewed-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-07-19i386: Allow KVM on i386 nonpaeAvi Kivity
Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of the cmpxchg64b feature and enables compilation of the set_64bit() family. Since the option is dependent on PAE, and since KVM depends on set_64bit(), this effectively disables KVM on i386 nopae. Simplify by removing the config option altogether: the boot check is made dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed without constraints. It is up to users to check for the feature flag (KVM does not as virtualiation extensions imply its existence).

2007-07-19hwmon/w83627ehf: Add error messages for two error casesDavid Hubbard
If the Super-I/O device is disabled, it is likely the BIOS has a good reason for leaving it disabled, so give a warning when enabling it -- it's not likely to be wired correctly or be able to give good data. Also, if the Super-I/O device is configured with an address of 0, the driver refuses to initialize it.
