2017-07-11mmc: sdhci-acpi: Workaround conflict with PCI wifi on GPD Win handheldAdrian Hunter
GPDwin uses PCI wifi which conflicts with SDIO's use of acpi_device_fix_up_power() on child device nodes. Specifically acpi_device_fix_up_power() causes the wifi module to get turned off. Identifying GPDwin is problematic, but since SDIO is only used for wifi, the presence of the PCI wifi card in the expected slot with an ACPI companion node, is used to indicate that acpi_device_fix_up_power() should be avoided.

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.

Pull followup NVMe (mostly) changes from Sagi: I added the quiesce/unquiesce patches in here as it's easy for me easily apply changes on top. It has accumulated reviews and includes mostly nvme anyway, please tell me if you don't want to take them with this. This includes: - quiesce/unquiesce fixes in nvme and others from me - nvme-fc add create association padding spec updates from James - some more quirking from MKP - nvmet nit cleanup from Max - Fix nvme-rdma racy RDMA completion signalling from Marta - some centralization patches from me - add tagset nr_hw_queues updates on controller resets in nvme drivers from me - nvme-rdma fix resources recycling when doing error recovery from me - minor cleanups in nvme-fc from me

2017-07-10drm/i915/fbdev: Check for existence of ifbdev->vma before operationsChris Wilson
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. This leaves a window of opportunity where we may try to operate on the fbdev prior to it being probed (thanks to asynchronous booting).

Currently when there is a reconfig, the uio_info->name does not get updated to reflect the change in the dev_config name change. On restart tcmu-runner there will be a mismatch between the dev_config string in uio and the tcmu structure that contains the string. When this occurs it'll reload the one in uio and you lose the reconfigured device path. v2: Created a helper function for the updating of uio_info Signed-off-by: Bryant G.

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.
