Don't hold the lock before unregistering the device, since when the device is unregistered the datastruct containing the lock may be freed (if the refcount went to 0). Also fixed the framework documentation that erroneously suggested the wrong locking order as well.

Drivers can optionally set a pointer to a mutex in struct video_device. The core will use that to lock before calling open, read, write, unlocked_ioctl, poll, mmap or release. Updated the documentation as well and ensure that v4l2-event knows about the lock: it will unlock it before doing a blocking wait on an event and relock it afterwards. Ensure that the 'video_is_registered' check is done when the lock is held: a typical disconnect will take the lock as well before unregistering the device nodes, so to prevent race conditions the video_is_registered check should also be done with the lock held.

Until now all fops except release and (unlocked_)ioctl returned an error after the device node was unregistered. Extend this as well to the ioctl fops. There is nothing useful that an application can do here and it complicates the driver code unnecessarily.

The driver author seems to not worked on this driver since its conversion from 2.2 to 2.4. Nobody is known to have a stradis hardware for testing. As it still uses V4L1 API, BKL and probably some other old stuff, someone would need to work on it to preserve the driver. Instead of investing time and efforts to keep porting it to work with new API's, it seems better to just drop the driver. So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody cares enough to port parallel port support to gspca or to create a new driver that uses the same gspca-cpia sub-driver.

cpia driver were re-written inside gspca driver, for USB devices. The only functionality that were not migrated is the support for parallel port, as: 1) the developer didn't find any hardware; 2) it doesn't seem important to keep support for a parallel port webcam, as this is an obsolete technology; 3) the changes at gspca for it to work with parallel port would be very large; 4) this driver still uses BKL. So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody cares enough to port parallel port support to gspca or to create a new driver that uses the same gspca-cpia sub-driver.

To help finding which ones were missed, allow printing out the unused ones as warnings.

After commit 852972ac (ACPI: Disable ASPM if the platform won't provide _OSC control for PCIe) control of the PCIe Capability Structure is unconditionally requested by acpi_pci_root_add(), which in principle may cause problems to happen in two ways. First, the BIOS may refuse to give control of the PCIe Capability Structure if it is not asked for any of the _OSC features depending on it at the same time. Second, the BIOS may assume that control of the _OSC features depending on the PCIe Capability Structure will be requested in the future and may behave incorrectly if that doesn't happen. For this reason, control of the PCIe Capability Structure should always be requested along with control of any other _OSC features that may depend on it (ie. PCIe native PME, PCIe native hot-plug, PCIe AER). Rework the PCIe port driver so that (1) it checks which native PCIe port services can be enabled, according to the BIOS, and (2) it requests control of all these services simultaneously. In particular, this causes pcie_portdrv_probe() to fail if the BIOS refuses to grant control of the PCIe Capability Structure, which means that no native PCIe port services can be enabled for the PCIe Root Complex the given port belongs to. If that happens, ASPM is disabled to avoid problems with mishandling it by the part of the PCIe hierarchy for which control of the PCIe Capability Structure has not been received. Make it possible to override this behavior using 'pcie_ports=native' (use the PCIe native services regardless of the BIOS response to the control request), or 'pcie_ports=compat' (do not use the PCIe native services at all). Accordingly, rework the existing PCIe port service drivers so that they don't request control of the services directly. Signed-off-by: NRafael J.

It is not immediately clear what this option causes to become ignored. The actual meaning is that it is not necessary to unplug the emulated devices to safely use the PV ones, even if the platform does not support the unplug protocol. (pressumably the user will only add this option if they have ensured that their domain configuration is safe). I think xen_emul_unplug=unnecessary better captures this.

Chapter 6 is right about mutex_trylock, but chapter 10 wasn't. This error was introduced during semaphore-to-mutex conversion of the Unreliable guide. :-) If user context which performs mutex_lock() or mutex_trylock() is preempted by interrupt context which performs mutex_trylock() on the same mutex instance, a deadlock occurs. This is because these functions do not disable local IRQs when they operate on mutex->wait_lock.
