Joshua Hoblitt reported that only 3 GB of his 16 GB of RAM is usable. Booting with mtrr_show showed us the BIOS-initialized MTRR settings - which are all wrong.

2008-08-21[S390] cio: call ccw driver notify function with lock heldPeter Oberparleiter
Calling a ccw driver's notify function without the ccw device lock held opens up a race window between discovery and handling of a change in the device operational state. As a result, the device driver may encounter unexpected device malfunction, leading to out-of-retry situations or similar.

2008-08-21[S390] dasd: fix data size for PSF/PRSSD commandStefan Weinhuber
The Perform Subsystem Function/Prepare for Read Subsystem Data command requires 12 bytes of parameter data, but the respective data structure dasd_psf_prssd_data has a length of 16 bytes. 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.

2008-08-21[S390] fix ext2_find_next_bitEric Sandeen
ext4 does not work on s390 because ext2_find_next_bit is broken. Fortunately this function is only used by ext4. The function uses ffs which does not work analog to ffz. The result of ffs has an offset of 1 which is not taken into account. To fix this use the low level __ffs_word function directly instead of the ill defined ffs. In addition the patch improves find_next_zero_bit and ext2_find_next_zero_bit by passing the bit offset into __ffz_word instead of adding it after the function call returned.

2008-08-21[S390] qdio: remove the module_get & module_put pairJan Glauber
Increasing the qdio reference count for every used subchannel is unnecessary since unloading qdio (if build as a module) is only possible if other modules that use qdio are unloaded.

In case of error, functions dasd_kmalloc_request and idal_buffer_alloc return an ERR pointer, but never return the NULL pointer.

2008-08-21USB: automatically enable RHSC interruptsAlan Stern
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.

2008-08-21USB: Don't rebind before "complete" callbackAlan Stern
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.

2008-08-21USB: Add new PM callback methods for USBAlan Stern
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.

2008-08-21USB: Defer Set-Interface for suspended devicesAlan Stern
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.

2008-08-21USB: Add udev argument to interface suspend/resume functionsAlan Stern
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>

If Indexed Mode register accesses are enabled, the ep0_rxstate() function calls musb_g_ep0_giveback() before writing to the CSR register. 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.

2008-08-21UIO: generic irq handling for some uio platform devicesMagnus Damm
This is V3 of uio_pdrv_genirq.c, a platform driver for UIO with generic IRQ handling code. This driver is very similar to the regular UIO platform driver, but is only suitable for devices that are connected to the interrupt controller using unique interrupt lines. The uio_pdrv_genirq driver includes generic interrupt handling code which disables the serviced interrupt in the interrupt controller and makes the user space driver responsible for acknowledging the interrupt in the device and reenabling the interrupt in the interrupt controller. Shared interrupts are not supported since the in-kernel interrupt handler will disable the interrupt line in the interrupt controller, and in a shared interrupt configuration this will stop other devices from delivering interrupts.

2008-08-21block: drop references taken by class_find_device()Kay Sievers
Otherwise we leak references, which is not a good thing to do. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-08-21block: fix partial read() of /proc/{partitions,diskstats}Kay Sievers
The proc files get truncated if they do not fit into the buffer with a single read(). We need to move the seq_file index from the callback of class_find_device() to the caller of class_find_device(), to keep its value across multiple invocations of the callback.

2008-08-21PM: Remove WARN_ON from device_pm_addRafael J. Wysocki
PM: Remove WARN_ON from device_pm_add Fix message in device_pm_add() saying that the device will not be added to dpm_list, although in fact the device is going to be added to the list regardless of the ordering violation. Remove the WARN_ON(true) triggered in that situation, because it is hit by USB very often and spams the users' logs. This patch fixes bug #11263 Signed-off-by: Rafael J.

2008-08-21driver core: add init_name to struct deviceGreg Kroah-Hartman
This gives us a way to handle both the bus_id and init_name values being used for a while during the transition period. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-08-21PM: don't skip device PM init when CONFIG_PM_SLEEP isn't set and CONFIG_PM ↵Alan Stern
is set This patch (as1124) fixes a couple of bugs in the PM core. The new dev->power.status field should be initialized regardless of whether CONFIG_PM_SLEEP is enabled, and similarly dpm_sysfs_add() should be called whenever CONFIG_PM is enabled. The patch separates out the call to dpm_sysfs_add() from the call to device_pm_add(). As a result device_pm_add() can no longer return an error, so its return type is changed to void.

Anti-oops medicine for the class iterators ... the oops was observed when a class was implicitly referenced before it was initialized.

2008-08-21dev_printk(): constify the `dev' argumentJean Delvare
Add const markings to dev_name and dev_driver_string to make it clear that dev_printk doesn't modify dev. This is a prerequisite to adding more const markings to other functions make it clearer, which functions can modify dev and which can't.
