2016-09-22nfs: use safe, interruptible sleeps when waiting to retry LOCKJeff Layton
We actually want to use TASK_INTERRUPTIBLE sleeps when we're in the process of polling for a NFSv4 lock. If there is a signal pending when the task wakes up, then we'll be returning an error anyway. So, we might as well wake up immediately for non-fatal signals as well. That allows us to return to userland more quickly in that case, but won't change the error that userland sees. Also, there is no need to use the *_unsafe sleep variants here, as no vfs-layer locks should be held at this point.

2016-09-22i2c / ACPI: Do not touch an I2C device if it belongs to another adapterMika Westerberg
When enumerating I2C devices connected to an I2C adapter we scan the whole namespace (as it is possible to have devices anywhere in that namespace, not just below the I2C adapter device) and add each found device to the I2C bus in question. Now after commit 525e6fabeae2 ("i2c / ACPI: add support for ACPI reconfigure notifications") checking of the adapter handle to the one found in the I2cSerialBus() resource was moved to happen after resources of the I2C device has been parsed. This means that if the I2cSerialBus() resource points to an adapter that does not exists in the system we still parse those resources. This is problematic in particular because acpi_dev_resource_interrupt() tries to configure GSI if the device also has an Interrupt() resource. Failing to do that results errrors like this to be printed on the console: [ 10.409490] ERROR: Unable to locate IOAPIC for GSI 37 To fix this we pass the I2C adapter to i2c_acpi_get_info() and make sure the handle matches the one in the I2cSerialBus() resource before doing anything else to the device.

2016-09-22percpu: improve generic percpu modify-return implementationNicholas Piggin
Some architectures require an additional load to find the address of percpu pointers. In some implemenatations, the C aliasing rules do not allow the result of that load to be kept over the store that modifies the percpu variable, which causes additional loads. Work around this by finding the pointer first, then operating on that. It's also possible to mark things as restrict and those kind of games, but that can require larger and arch specific changes.

At least check for the variables to be non-zero before dividing. This happened for a system with WinTV HVR-4400 PCIe-card after suspend-to-disk. Do suspend-to-disk without accessing the DVB device before. After wakeup try to tune. si2165_init fails at checking the chip_mode and aborts. Then si2165_set_if_freq_shift will fail with div-by-zero.

2016-09-22[media] cx25821: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
The workqueue "_irq_audio_queues" runs the audio upstream handler. It has a single work item(&dev->_audio_work_entry) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. The work item has been flushed in cx25821_stop_upstream_audio() to ensure that nothing is pending when the driver is disconnected.

2016-09-22blk-mq: get rid of manual run of queue with __blk_mq_run_hw_queue()Jens Axboe
Two cases: 1) blk_mq_alloc_request() needlessly re-runs the queue, after calling into the tag allocation without NOWAIT set. We don't need to do that. 2) blk_mq_map_request() should just use blk_mq_run_hw_queue() with the async flag set to false.

2016-09-22[media] dvb-usb: avoid link error with dib3000m{b,c|Arnd Bergmann
Tha ARM randconfig builds came up with another rare build failure for the dib3000mc driver, when dvb-usb-dibusb-mb is built-in and dib3000mc is a loadable module: ERROR: "dibusb_dib3000mc_frontend_attach" [drivers/media/usb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! ERROR: "dibusb_dib3000mc_tuner_attach" [drivers/media/usb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! Apparently this used to be a valid configuration (build-time, not run-time), but broke as part of a cleanup. I tried reverting the cleanup, but saw that the code was still wrong then. This version adds a dependency for dib3000mb, to ensure that dib3000mb does not force the dibusb_dib3000mc_frontend_attach function to be built-in when dib3000mc is a loadable module. I have also checked the two other files that were changed in the original cleanup, and found them to be correct in either version, so I do not touch that part. As this is a rather obscure bug, there is no need for backports.

2016-09-22[media] dvb-usb: split out common parts of dibusbArnd Bergmann
Tha ARM randconfig builds came up with another rare build failure for the dib3000mc driver, when dvb-usb-dibusb-mb is built-in and dib3000mc is a loadable module: ERROR: "dibusb_dib3000mc_frontend_attach" [drivers/media/usb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! ERROR: "dibusb_dib3000mc_tuner_attach" [drivers/media/usb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! Apparently this used to be a valid configuration (build-time, not run-time), but broke as part of a cleanup. I tried reverting the cleanup, but saw that the code was still wrong then. This tries to fix the code properly, by moving the problematic functions into a new file that now is built as a loadable module or built-in, whichever is correct for a particular configuration. It fixes the regression as well as the runtime problem that already existed. The new module dependency chain is now: dvb-usb-{dibusb_mc,a800,dib0700,umt-010,gp8psk} dvb-usb-dibusb-mb | | | | dvb-usb-dibusb-mc-common | ___________| | | | | | | dib3000mc (frontend) | | | dib3000mb (frontend) | | | | | | dvb-usb-dibusb-common I have also checked the two other files that were changed in the original cleanup, and found them to be correct in either version, so I do not touch that part.
