* [PATCH] Initialise SAK member for each virtual console to prevent oopsBernhard Walle2007-03-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initialise the SAK member of the vc_cons variable on all virtual terminals, not only the first one.

* [PATCH] gpio_direction_output() needs an initial valueDavid Brownell2007-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

* [PATCH] spi: destroy workqueue after spi_unregister_masterChris Lesiak2007-03-161-24/+2
| | | | | | | | | | | | | | | | | Fix a bug in the cleanup of an spi_bitbang bus. The workqueue associated with the bus was destroyed before the call to spi_unregister_master. That meant that spi devices on that bus would be unable to do IO in their remove method. The shutdown flag should have been able to prevent a segfault, but was never getting set. By waiting to destroy the workqueue until after the master is unregistered, devices are able to do IO in their remove methods. An added benefit is that neither the shutdown flag nor a wait for the queue of messages to empty is needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt status register for the natsemi chips is clear on read and was read unconditionally from both the interrupt and from the NAPI poll routine, meaning that if the interrupt service routine was called (for example, due to a shared interrupt) while a NAPI poll was scheduled interrupts could be missed. This patch fixes that by ensuring that the interrupt status register is only read by the interrupt handler when interrupts are enabled from the chip. It also reverts a workaround for this problem from the netpoll hook and improves the trace for interrupt events.

This patch changes the code paths that touch the interrupt enable register to use the functions. In all cases this adds an extra PCI read to post the operation but since none of these are in fast paths this shouldn't be too much of a problem.

When this happens as the result of another port going down, the phy_mutex that is common to both ports is held, so it deadlocks. Setting the address doesn't need to do anything that needs the phy_mutex, it already has the RTNL to protect against other admin actions. This change just disables the receiver to avoid any hardware confusion while address is changing.

* | [PATCH] sysfs and driver core: add callback helper, used by SCSI and S390Alan Stern2007-03-153-4/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes bogus zeroing of unused bits in output reports, introduced in Simon's patch in commit d4ae650a. According to the specification, any sane device should not care about values of unused bits. What is worse, the zeroing is done in a way which is broken and might clear certain bits in output reports which are actually _used_ - a device that has multiple fields with one value of the size 1 bit each might serve as an example of why this is bogus - the second call of hid_output_report() would clear the first bit of report, which has already been set up previously. This patch will break LEDs on SpaceNavigator, because this device is broken and takes into account the bits which it shouldn't touch. The quirk for this particular device will be provided in a separate patch. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

This structue has a very short life, it's destroyed as soon as the report descriptor has been completely parsed. This should be considered a temporary solution, until the hid_parser is rewritten to consume less memory during report descriptor parsing.

* | | | [PATCH] pci: Repair pci_save/restore_state so we can restore one save many ↵Eric W. Biederman2007-03-121-6/+6

Because we do not reserve space for the pci-x and pci-e state in struct pci dev we need to dynamically allocate it. However because we need to support restore being called multiple times after a single save it is never safe to free the buffers we have allocated to hold the state. So this patch modifies the save routines to first check to see if we have already allocated a state buffer before allocating a new one. Then the restore routines are modified to not free the state after restoring it. Simple and it fixes some subtle error path handling bugs, that are hard to test for. Signed-off-by: Eric W.

* | | | [PATCH] msi: Safer state caching.Eric W. Biederman2007-03-123-129/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two ways pci_save_state and pci_restore_state are used. As helper functions during suspend/resume, and as helper functions around a hardware reset event. When used as helper functions around a hardware reset event there is no reason to believe the calls will be paired, nor is there a good reason to believe that if we restore the msi state from before the reset that it will match the current msi state. Since arch code may change the msi message without going through the driver, drivers currently do not have enough information to even know when to call pci_save_state to ensure they will have msi state in sync with the other kernel irq reception data structures. It turns out the solution is straight forward, cache the state in the existing msi data structures (not the magic pci saved things) and have the msi code update the cached state each time we write to the hardware. This means we never need to read the hardware to figure out what the hardware state should be. By modifying the caching in this manner we get to remove our save_state routines and only need to provide restore_state routines. The only fields that were at all tricky to regenerate were the msi and msi-x control registers and the way we regenerate them currently is a bit dependent upon assumptions on how we use the allow msi registers to be configured and used making the code a little bit brittle. If we ever change what cases we allow or how we configure the msi bits we can address the fragility then. Signed-off-by: Eric W.
