* cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystemKay Sievers2011-12-2138-877/+874
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the 'cpu sysdev_class' over to a regular 'cpu' subsystem and converts the devices to regular devices. The sysdev drivers are implemented as subsystem interfaces now. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are made available with this conversion.

* driver-core: implement 'sysdev' functionality for regular devices and busesKay Sievers2011-12-147-62/+431
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | All sysdev classes and sysdev devices will converted to regular devices and buses to properly hook userspace into the event processing. There is no interesting difference between a 'sysdev' and 'device' which would justify to roll an entire own subsystem with different userspace export semantics. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are currently not properly available. Every converted sysdev class will create a regular device with the class name in /sys/devices/system and all registered devices will becom a children of theses devices. For compatibility reasons, the sysdev class-wide attributes are created at this parent device. (Do not copy that logic for anything new, subsystem- wide properties belong to the subsystem, not to some fake parent device created in /sys/devices.) Every sysdev driver is implemented as a simple subsystem interface now, and no longer called a driver. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel.

* kref: fix up the kfree build problemsGreg Kroah-Hartman2011-12-141-5/+10
| | | | | | | | | | | | | | | | | | | | | | | It turns out that some memory allocators use kobjects, which use krefs, and kref.h was wanting to figure out the address of kfree(), which ended up in a loop. kfree was only being needed for a warning to tell the caller that they were doing something stupid. Now we just move that warning into the comments for the functions, which results in a bit more fun as everyone enjoys digging for people to mock at times of boredom. So, remove the dependancy of slab.h on kref.h, and fix up the other include file as well (we really only need bug.h and atomic.h, not types.h).

* kref: Remove the memory barriersPeter Zijlstra2011-12-131-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1b0b3b9980e ("kref: fix CPU ordering with respect to krefs") wrongly adds memory barriers to kref. It states: some atomic operations are only atomic, not ordered. Thus a CPU is allowed to reorder memory references to an object to before the reference is obtained. This fixes it. While true, it fails to show why this is a problem. I say it is not a problem because if there is a race with kref_put() such that we could end up referencing a free'd object without this memory barrier, we would still have that race with the memory barrier. The kref_put() in question could complete (and free the object) before the atomic_inc() and we'd still be up shit creek. The kref_init() case is even worse, if your object is published at this time you're so wrong the memory barrier won't make a difference what so ever. If its not published, the act of publishing should include the needed barriers/locks to make sure all writes prior to the act of publishing are complete such that others will only observe a complete object.

* USB: Add helper macro for usb_driver boilerplateGreg Kroah-Hartman2011-11-171-0/+12
| | | | | | | | | | | | | | This patch introduces the module_usb_driver macro which is a convenience macro for USB driver modules similar to module_platform_driver. It is intended to be used by drivers which init/exit section does nothing but register/unregister the USB driver. By using this macro it is possible to eliminate a few lines of boilerplate code per USB driver. Based on work done by Lars-Peter Clausen <lars@metafoo.de> for other busses (i2c and spi).

* drivercore: Generalize module_platform_driverLars-Peter Clausen2011-11-172-10/+23
| | | | | | | | | | | | | | | | | | | This patch generalizes the module_platform_driver macro and introduces a new module_driver macro. The module_driver macro takes a driver name, a register and a unregister function for this driver type. Using these it construct the module init and exit sections which register and unregister the driver. Since such init/exit sections are commonly found in drivers this macro can be used to eliminate a lot of boilerplate code. The macro is not intended to be used by driver modules directly, instead it should be used to generate bus specific macros for registering drivers like the module_platform_driver macro.

* W1: w1_therm: release the bus during conversion on externally powered devicesMaciej Szmigiero2011-11-171-5/+31
| | | | | | | | | | | | | | | | | | | | | | | | w1_therm devices can either be bus powered or externally powered. When device is bus powered during temperature conversion the bus have to be left high to provide necessary power. Some masters also allow strong power-up to be enabled in this case. Naturally, no communication over bus can occur during that time. However, if device has external power then there is no such restriction, and host can talk to other devices during temperature conversion. There is command which allows us to check how device is powered, this patch uses it to release the bus on externally w1_therm powered devices during temperature conversion. Also, this changes uninterruptible sleeps there into interruptible ones to avoid long uninterruptible sleep if w1 subsystem happens to grab bus for scan during w1_therm_read().
