| * | | USB: automatically enable RHSC interruptsAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1069c) changes the way OHCI root-hub status-change interrupts are enabled. Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

| * | | USB: Don't rebind before "complete" callbackAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1130) fixes an incompatibility between the new PM infrastructure and USB power management. We are not allowed to call drivers' probe routines during a system sleep transition between the "prepare" and "complete" callbacks, but that's exactly what we do when a driver doesn't have full suspend/resume support. Such drivers are unbound during the "suspend" call and reprobed during the "resume" call. The patch causes the reprobe step to be skipped if the "complete" callback hasn't been issued yet, i.e., if the interface's dev.power.status field is not equal to DPM_ON. Thus during the "resume" callback nothing bad will happen, and during the final "complete" callback the reprobing will occur as desired. This fixes the problem reported in Bugzilla #11263.

| * | | USB: Add new PM callback methods for USBAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1129) adds support for the new PM callbacks to usbcore. The new callbacks merely invoke the same old USB power management routines as the old ones did. A minor improvement is that the callbacks are present only in the "USB-device" device_type structure, rather than in the bus_type structure. This way they will be invoked only for USB devices, not for USB interfaces. The core USB PM routines automatically handle suspending and resuming interfaces along with their devices.

| * | | USB: Defer Set-Interface for suspended devicesAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1128) fixes one of the problems related to the new PM infrastructure. We are not allowed to register new child devices during the middle of a system sleep transition, but unbinding a USB driver causes the core to automatically install altsetting 0 and thereby create new endpoint pseudo-devices. The patch fixes this problem (and the related problem that installing altsetting 0 will fail if the device is suspended) by deferring the Set-Interface call until some later time when it is legal and can succeed. Possible later times are: when a new driver is being probed for the interface, and when the interface is being resumed.

| * | | USB: Add udev argument to interface suspend/resume functionsAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1127) makes a minor change to the prototypes of the usb_suspend_interface() and usb_resume_interface() routines. Now the usb_device structure is passed as an argument, instead of being computed on-the-fly from the usb_interface argument. It makes the code look simpler, even if it really isn't much different from before. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * | | MUSB: Fix index register corruption seen with g_ether and Windows hostAnand Gadiyar2008-08-21

When control returns to this ep0_rxstate, the index register contents are over-written. This causes the CSR register write to fail. Fixed by writing the correct value into the index register before writing to the CSR. This was observed only in ep0_rxstate() with g_ether loaded and the device connected to a MS Windows host PC. Anticipatively fixed ep0_txstate() as well. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Acked-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Current storage servers ignore the obsolete bytes, but older models fail to execute the command and report an incorrect length error. This causes the device initilization for these devices to fail. To fix this problem we need to correct the dasd_psf_prssd_data structure and shorten it to the correct length.

Fix current compile issue by using struct i2c_client member "name" instead of "driver_name". Also, add id_table to make sure the device gets properly detected.

| * | | powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devicesJoachim Fenkes2008-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the client virtual fibre channel adapter is already logged into the server and does an NPIV Login again, the async queue, which is used for reporting Link Up/Link Down type of events, does not get reset on the server side. Fix up the client driver so that we also do not reset it. This fixes a problem of lost async events following relogins.

However, the hosts's state does not get set back to IBMVFC_INITIALIZING and scsi_block_requests does not get called again, which can result in queuecommand ops getting sent during discovery. This should not occur and may cause problems. One example is that we may no longer be logged into the target we send the command to, resulting in a failure which should not have occurred.

| * | | | [SCSI] ibmvfc: Fix another hang on module removalBrian King2008-08-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a hang on module removal. The module removal code was setting the hosts's state to IBMVFC_HOST_OFFLINE before tearing down the kernel thread, but, due to a bug in ibmvfc_wait_while_resetting, was not waiting for the kernel thread's offlining work to be done prior to destroying the kernel thread, which left the scsi host in a blocked state which we never got out of.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running ibmvscsi in a shared memory partition, it must provide a default value for the amount of DMA resources it will need in order to perform reasonably well. This was being calculated in sectors rather than bytes, as it should. This patch fixes this.
