* Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wqLinus Torvalds2012-10-021-1/+1

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() ...
| * workqueue: deprecate flush[_delayed]_work_sync()Tejun Heo2012-08-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flush[_delayed]_work_sync() are now spurious. 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.

The upside is that we look like we can introduce tty_port_easy_open and put it directly as tty_operations->open to drivers doing nothing in open and using tty_port_register_device. Because the easy open can obtain a tty_port rather easily from a tty now. Heh, what a nice by-product.

But this PCI device has two functions with interrupt lines connected to a single pin. The other one is a USB host controller. So when we disable the PIN there e.g. by rmmod hpilo, the controller stops working. It is because the interrupt link is disabled in ACPI since it is not refcounted yet. See acpi_pci_link_free_irq called from acpi_pci_irq_disable. It is not the best solution whatsoever, but as a workaround until the ACPI irq link refcounting is sorted out this should fix the reported errors.

These new bindings also happen to be deployed in the field and were previously submitted for consideration here: https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-May/015556.html The advantages of the new bindings are that they are similar to the I2C EEPROMs and they don't conflate read-only and the address width modes in a binary encoded blob.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before calling on any of the platform hooks, shared transport driver checks for the validity of the platform hooks as to whether it is provided or not. A wrong function was being checked for, before the chip_awake hook was called by the HCI-LL sleep logic handler. This patch corrects the check.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A platform hook to enable/disable the chip was introduced to perform specific activities to power-up and power-down the WL chip. Moving the power-up/down sequence also there makes more sense, since different platforms have begun to have their own ways to power-up/down the chip. This patch removes all of the gpio handling done by the driver in st_kim_start/st_kim_stop & any of the gpio request done in the probe function.

This was historical, and is no longer needed. Recent changes to the drivers/dma/fsldma.c driver have removed support for this flag.
