A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.

* USB: gpio_vbus: use cached IRQ number for consistency with the probed oneShinya Kuribayashi2012-05-171-4/+6
| | | | | | | | | | | | | | | | | | gpio_vbus is designed to be able to get an IRQ number for VBUS change interrupt either (1) through platform_get_resource(IORESOURCE_IRQ) or (2) by processing gpio_to_irq(pdata->gpio_vbus), in probe() function. On the other hand, gpio_vbus_set_peripheral() and gpio_vbus_remove() are always doing gpio_to_irq(pdata->gpio_vbus) to get an IRQ number. This is not just inconsistent, but also broken. There is no guarantee that an IRQ number obtained by platform_get_resource() is equal to gpio_to_irq(pdata->gpio_vbus). Cache an IRQ number in probe() function, and use it where necessary.

* USB: gpio_vbus: avoid consecutive vbus_session calls with the same "is_active"Shinya Kuribayashi2012-05-141-2/+10
| | | | | | | | | | | | | | | | | | | Basically, ->vbus_session() calls should be served when VBUS session starts and ends (it's not whenever transciever drivers detect VBUS _changes_). Otherwise, if UDC gadget drivers don't want for some reason ->vbus_session() calls with the same "is_active" value, either OTG or UDC drivers need to have some protection handlings. Also, on platforms using this 'gpio_vbus' driver, the driver is only allowed to check whether VBUS is applied. There is no kernel-standard way prepared for UDC gadget drivers to do that. With this in mind, gpio_vbus should try to prevent unnecessary consecutive vbus_session calls being served with the same "in_active" value.

* USB: gpio_vbus: provide an appropriate debounce intervalShinya Kuribayashi2012-05-141-4/+4
| | | | | | | | | | | | | | | | | | In commit c2344f13b59e007d782a3e591ebc551bc583a8b7 (USB: gpio_vbus: add delayed vbus_session calls, 2009-01-24), usb_gadget_vbus_connect() and ...disconnect() were extracted from the interrupt handler, so to allow vbus_session handlers to deal with msleep() calls. This patch takes the approach one step further. USB2.0 specification (7.1.7.3 Connect and Disconnect Signaling) says that the USB system software (shall) provide a debounce interval with a minimum duration of 100 ms, which ensures that the electrical and mechanical connection is stable before software attempts to reset the attached device.
