2010-03-08[WATCHDOG] i6300esb.c: change platform_driver to pci_driverWim Van Sebroeck
Since the intel 6300esb platform uses a dedicated PCI ID for it's watchdog timer (00:1d.4), it's better and easier to have this as a pci_driver. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2010-03-08[S390] smsgiucv_app: deliver z/VM CP special messages (SMSG) as ueventsHendrik Brueckner
The smsgiucv_app driver registers a callback with the smsgiucv driver to receive z/VM CP special messages (SMSG) starting with "APP". When the callback is called for special messages, the driver creates an uevent for the received message. The uevent consists of additional environment data containing the message prefix ("APP"), message sender, and message content. udev rules can be used to trigger application specific actions through matching the content or sender of the special message.

2010-03-08[S390] hvc_iucv: allocate memory buffers for IUCV in zone DMAHendrik Brueckner
The device driver must allocate memory for IUCV buffers with GFP_DMA, because IUCV cannot address memory above 2GB (31bit addresses only). Because the IUCV ignores the higher bits of the address, sending and receiving IUCV data with this driver might cause memory corruptions.

2010-03-08[WATCHDOG] i6300esb: fix unlock register withWim Van Sebroeck
Before you can read or write from the i6300esb memeory mapped registers, you need to unlock these. This is done by writing the magic numbers 0x80 and 0x86 to the reload register. The size of the reload register is 32bit though. Also binary 11 is hex 0x03 and not 0x11. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

Without SCM, user cann't on/off 3G module on those 3G netbook.

2010-03-07Driver core: create lock/unlock functions for struct deviceGreg Kroah-Hartman
In the future, we are going to be changing the lock type for struct device (once we get the lockdep infrastructure properly worked out) To make that changeover easier, and to possibly burry the lock in a different part of struct device, let's create some functions to lock and unlock a device so that no out-of-core code needs to be changed in the future. This patch creates the device_lock/unlock/trylock() functions, and converts all in-tree users to them.

Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.

2010-03-07sysdev: fix up the probe/release attributesGreg Kroah-Hartman
These should be sysdev attributes, not class attributes. This patch should resolve the problem. Thanks to Stephen Rothwell for pointing out the problem. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Andi Kleen <andi@firstfloor.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-07kobject: Constify struct kset_uevent_opsEmese Revfy
Constify struct kset_uevent_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-07driver-core: firmware_class: remove base.h header inclusionLuis R. Rodriguez
base.h is used by base drivers for sharing internal structures. Turns out firmware_class does not depend on it at all so remove it.

2010-03-07Driver-Core: devtmpfs - reset inode permissions before unlinkingKay Sievers
Before unlinking the inode, reset the current permissions of possible references like hardlinks, so granted permissions can not be retained across the device lifetime by creating hardlinks, in the unusual case that there is a user-writable directory on the same filesystem.

2010-03-07driver core: Convert some drivers to CLASS_ATTR_STRINGAndi Kleen
Convert some drivers who export a single string as class attribute to the new class_attr_string functions. This removes redundant code all over. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-07driver core: Add class_attr_string for simple read-only stringAndi Kleen
Several drivers just export a static string as class attributes. Use the new extensible attribute support to define a simple CLASS_ATTR_STRING() macro for this. This will allow to remove code from drivers in followon patches. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-07driver-core: Add attribute argument to class_attribute show/storeAndi Kleen
Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-03-07sysfs: Add attribute array to sysdev classesAndi Kleen
Add a attribute array that is automatically registered and unregistered to struct sysdev_class. This is similar to what struct class has. A lot of drivers add list of attributes, so it's better to do this easily in the common sysdev layer. This adds a new field to struct sysdev_class. I audited the whole tree and there are no dynamically allocated sysdev classes, so this is fully compatible.
