2009-11-09pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (misc drivers)Dominik Brodowski
Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of requiring manual settings of PCMCIA_DEBUG. Also, remove all usages of the CS_CHECK macro and replace them with proper Linux style calling and return value checking. The extra error reporting may be dropped, as the PCMCIA core already complains about any (non-driver-author) errors.

2009-10-14usb-storage: Workaround devices with bogus sense sizeBenjamin Herrenschmidt
usb-storage: Workaround devices with bogus sense size Some devices, such as Huawei E169, advertise more than the standard amount of sense data, causing us to set US_FL_SANE_SENSE, assuming they support it. However, they subsequently fail the request sense with that size. This works around it generically. When a sense request fails due to a device returning an error, US_FL_SANE_SENSE was set, and that sense request used a larger sense size, we retry with a smaller size before giving up.

2009-10-14USB: ehci: Fix IST boundary checking interval math.Sarah Sharp
When the EHCI driver falls behind in its scheduling, the active stream's first empty microframe may be in the past with respect to the current microframe. The code attempts to move the starting microframe ("start") N number of microframes forward, where N is the interval of endpoint. However, stream->interval is a copy of the endpoint's bInterval, which is designated in frames for FS devices, and microframes for HS devices. Convert stream->interval to microframes before using it to move the starting microframe forward.

2009-10-11Revert "USB: Work around BIOS bugs by quiescing USB controllers earlier"Linus Torvalds
This reverts commit db8be50c4307dac2b37305fc59c8dc0f978d09ea, as per http://bugzilla.kernel.org/show_bug.cgi?id=14374 http://marc.info/?l=linux-kernel&m=125446885705223&w=4 We simply can't do the USB handoff at FIXUP_HEADER time, since it will often require us to have valid IO mappings etc. But that in turn requires a whole different approach, not this trivial one-liner. Maybe we could teach all the USB quirk handoff handlers to only do the quirk if the device has all its registers set up (since if it isn't initialized, it's unlikely to be active), but regardless that will need a whole lot more code than just saying "let's do it really early". The proper fix is almost certainly to just leave the legacy IOMMU mappings active until after all devices have been initialized.

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().

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.

Rework the r8a66597-udc fifo code to avoid unaligned accesses. Without this patch unaligned exceptions will degrade the USB performance. The exceptions come from the fact that the usb fifo data buffers may be misaligned. This patch updates the fifo access code to only use insl()/outsl() and insw()/outsw() in the case of properly aligned data buffers. The fallback case is that inl()/inw() are used for misaligned buffer reads together with outb() that is used for misaligned buffer writes.

2009-09-27tty: Fix regressions caused by commit b50989dcDave Young
The following commit made console open fails while booting: commit b50989dc444599c8b21edc23536fc305f4e9b7d5 Author: Alan Cox <alan@linux.intel.com> Date: Sat Sep 19 13:13:22 2009 -0700 tty: make the kref destructor occur asynchronously Due to tty release routines run in a workqueue now, error like the following will be reported while booting: INIT open /dev/console Input/output error It also causes hibernation regression to appear as reported at http://bugzilla.kernel.org/show_bug.cgi?id=14229 The reason is that now there's latency issue with closing, but when we open a "closing not finished" tty, -EIO will be returned. Fix it as per the following Alan's suggestion: Fun but it's actually not a bug and the fix is wrong in itself as the port may be closing but not yet being destructed, in which case it seems to do the wrong thing. Opening a tty that is closing (and could be closing for long periods) is supposed to return -EIO. I suspect a better way to deal with this and keep the old console timing is to split tty->shutdown into two functions. tty->shutdown() - called synchronously just before we dump the tty onto the waitqueue for destruction tty->cleanup() - called when the destructor runs. We would then do the shutdown part which can occur in IRQ context fine, before queueing the rest of the release (from tty->magic = 0 ... the end) to occur asynchronously The USB update in -next would then need a call like if (tty->cleanup) tty->cleanup(tty); at the top of the async function and the USB shutdown to be split between shutdown and cleanup as the USB resource cleanup and final tidy cannot occur synchronously as it needs to sleep. In other words the logic becomes final kref put make object unfindable async clean it up Signed-off-by: Dave Young <hidave.darkstar@gmail.com> [ rjw: Rebased on top of 2.6.31-git, reworked the changelog. ] Signed-off-by: "Rafael J.
