2017-07-11drm/i915/gvt: remove scheduler_mutex in per-engine workload_threadWeinan Li
For the vGPU workloads, now GVT-g use per vGPU scheduler, the per-ring work_thread only pick workload belongs to the current vGPU. And with time slice based scheduler, it waits all the engines become idle before do vGPU switch. So we can run free dispatch in per-ring work_thread, different ring running in different 'vGPU' won't happen. For the workloads between vGPU and Host, this scheduler_mutex can't block host to dispatch workload into other ring engines. Here remove this mutex since it impacts the performance when applications use more than 1 ring engines in 1 vgpu. ring0 running in vGPU1, ring1 running in Host. Will happen. ring0 running in vGPU1, ring1 running in vGPU2. Won't happen.

This reverts commit 62d02fd1f807bf5a259a242c483c9fb98a242630. The rwsem recursive trace should not be fixed from kvmgt side by using a workqueue and it is an issue should be fixed in VFIO.

2017-07-10Raid5 should update rdev->sectors after reshapeXiao Ni
The raid5 md device is created by the disks which we don't use the total size. For example, the size of the device is 5G and it just uses 3G of the devices to create one raid5 device. Then change the chunksize and wait reshape to finish. After reshape finishing stop the raid and assemble it again. It fails. mdadm -CR /dev/md0 -l5 -n3 /dev/loop[0-2] --size=3G --chunk=32 --assume-clean mdadm /dev/md0 --grow --chunk=64 wait reshape to finish mdadm -S /dev/md0 mdadm -As The error messages: [197519.814302] md: loop1 does not have a valid v1.2 superblock, not importing! [197519.821686] md: md_import_device returned -22 After reshape the data offset is changed. It selects backwards direction in this condition. In function super_1_load it compares the available space of the underlying device with sb->data_size. The new data offset gets bigger after reshape. So super_1_load returns -EINVAL. rdev->sectors is updated in md_finish_reshape. Then sb->data_size is set in super_1_sync based on rdev->sectors. So add md_finish_reshape in end_reshape.

Commit fabef825626d ("drm/i915: Drop struct_mutex around frontbuffer flushes") adds a dependency to ifbdev->vma when flushing the framebufer, but the checks are only against the existence of the ifbdev->fb and not against ifbdev->vma.

2017-07-09Input: gpio_keys - handle the missing key press event in resume phaseJoseph Lo
The GPIO key press event might be missed in the resume phase, if the key had been released before the system had been resumed to the stage that it could capture the press event. So we simulate the wakeup key press event in case the key had been released by the time we got interrupt handler to run.

2017-07-09iio: adc: axp288: Fix the GPADC pin reading often wrongly returning 0Hans de Goede
I noticed in its DSDT that one of my tablets actually is using the GPADC pin for temperature monitoring. The whole axp288_adc_set_ts() function is a bit weird, in the past it was removed because it seems to make no sense, then this was reverted because of regressions. So I decided to test the special GPADC pin handling on this tablet. Conclusion: not only is axp288_adc_set_ts() necessary, we need to sleep a bit after making the AXP288_ADC_TS_PIN_CTRL changes before sampling the GPADC, otherwise it will often (about 80% of the time) read 0 instead of its actual value. It seems that there is only 1 bias current source and to be able to use it for the GPIO0 pin in GPADC mode it must be temporarily turned off for the TS pin, but the datasheet does not mention this. This commit adds a sleep after disabling the TS pin bias current, fixing the GPADC more often then not wrongly returning 0.

2017-07-08bonding: avoid NETDEV_CHANGEMTU event when unregistering slaveWANG Cong
As Hongjun/Nicolas summarized in their original patch: " When a device changes from one netns to another, it's first unregistered, then the netns reference is updated and the dev is registered in the new netns. Thus, when a slave moves to another netns, it is first unregistered. This triggers a NETDEV_UNREGISTER event which is caught by the bonding driver. The driver calls bond_release(), which calls dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in the old netns). " This is a very special case, because the device is being unregistered no one should still care about the NETDEV_CHANGEMTU event triggered at this point, we can avoid broadcasting this event on this path, and avoid touching inetdev_event()/addrconf_notify() path. It requires to export __dev_set_mtu() to bonding driver.
