2016-02-10workqueue: handle NUMA_NO_NODE for unbound pool_workqueue lookupTejun Heo
When looking up the pool_workqueue to use for an unbound workqueue, workqueue assumes that the target CPU is always bound to a valid NUMA node. However, currently, when a CPU goes offline, the mapping is destroyed and cpu_to_node() returns NUMA_NO_NODE. This has always been broken but hasn't triggered often enough before 874bbfe600a6 ("workqueue: make sure delayed work run in local cpu"). After the commit, workqueue forcifully assigns the local CPU for delayed work items without explicit target CPU to fix a different issue. This widens the window where CPU can go offline while a delayed work item is pending causing delayed work items dispatched with target CPU set to an already offlined CPU. The resulting NUMA_NO_NODE mapping makes workqueue try to queue the work item on a NULL pool_workqueue and thus crash. While 874bbfe600a6 has been reverted for a different reason making the bug less visible again, it can still happen. Fix it by mapping NUMA_NO_NODE to the default pool_workqueue from unbound_pwq_by_node(). This is a temporary workaround. The long term solution is keeping CPU -> NODE mapping stable across CPU off/online cycles which is being worked on.

2016-02-10efi: Make efivarfs entries immutable by defaultPeter Jones
"rm -rf" is bricking some peoples' laptops because of variables being used to store non-reinitializable firmware driver data that's required to POST the hardware. These are 100% bugs, and they need to be fixed, but in the mean time it shouldn't be easy to *accidentally* brick machines. We have to have delete working, and picking which variables do and don't work for deletion is quite intractable, so instead make everything immutable by default (except for a whitelist), and make tools that aren't quite so broad-spectrum unset the immutable flag.

So the device id and rom version have to be stored in the driver's state to know what variant is a given device. While being there, remove some redundant comments about the device version since there is already calls to v4l2_info() with that info.

2016-02-10[media] v4l2-async: call registered_async after subdev registrationJavier Martinez Canillas
V4L2 sub-devices might need to do initialization that depends on being registered with a V4L2 device. As an example, sub-devices with Media Controller support may need to register entities and create pad links. Execute the registered_async callback after the sub-device has been registered with the V4L2 device so the driver can do any needed init.

2016-02-10[media] v4l2-subdev: add registered_async subdev core operationJavier Martinez Canillas
V4L2 sub-devices that are registered asynchronously have no way to know when they have been registration with a V4L2 device but they might need to take some action after this. So let's add a callback that can be executed by the V4L2 async core to allow sub-devices drivers to do any needed initialization that depends on the registration.

v4l2_ctrl_add_ctrl() interface has no users since its introduction in commit 0996517cf8ea ("V4L/DVB: v4l2: Add new control handling framework") and its functionality is covered by v4l2_ctrl_new() and derivative interfaces, so it is safe to remove the interface from the kernel.
