2020-01-07drm/i915/gt: Always force restore freshly pinned contextsChris Wilson
It is highly unlikely, but still conceivable, that we submit a context with the same GGTT address as last active on the HW. In this case, with a matching LRCA, the HW would not restore the new context image causing a potential violation of our context isolation.

2020-01-07ASoC: Fix NULL dereference at freeingTakashi Iwai
When an ASoC driver with pcm_destruct component ops is freed before the PCM object instantiation (e.g. deferring the probe), it hits an Oops at snd_soc_pcm_component_free() that calls the pcm_destruct ops unconditionally. Fix it by adding a NULL-check of rtd->pcm before calling callbacks.

2020-01-07vlan: fix memory leak in vlan_dev_set_egress_priorityEric Dumazet
There are few cases where the ndo_uninit() handler might be not called if an error happens while device is initialized. Since vlan_newlink() calls vlan_changelink() before trying to register the netdevice, we need to make sure vlan_dev_uninit() has been called at least once, or we might leak allocated memory.

2020-01-07io_uring: remove punt of short reads to async contextJens Axboe
We currently punt any short read on a regular file to async context, but this fails if the short read is due to running into EOF. This is especially problematic since we only do the single prep for commands now, as we don't reset kiocb->ki_pos. This can result in a 4k read on a 1k file returning zero, as we detect the short read and then retry from async context. At the time of retry, the position is now 1k, and we end up reading nothing, and hence return 0. Instead of trying to patch around the fact that short reads can be legitimate and won't succeed in case of retry, remove the logic to punt a short read to async context. Simply return it.

2020-01-07i40iw: Remove setting of VMA private data and use rdma_user_mmap_ioShiraz Saleem
vm_ops is now initialized in ib_uverbs_mmap() with the recent rdma mmap API changes. Earlier it was done in rdma_umap_priv_init() which would not be called unless a driver called rdma_user_mmap_io() in its mmap. i40iw does not use the rdma_user_mmap_io API but sets the vma's vm_private_data to a driver object. This now conflicts with the vm_op rdma_umap_close as priv pointer points to the i40iw driver object instead of the private data setup by core when rdma_user_mmap_io is called. This leads to a crash in rdma_umap_close with a mmap put being called when it should not have. Remove the redundant setting of the vma private_data in i40iw as it is not used. Also move i40iw over to use the rdma_user_mmap_io API. This gives the extra protection of having the mappings zapped when the context is detsroyed.

2020-01-07drm/amd/display: Reduce HDMI pixel encoding if max clock is exceededThomas Anderson
For high-res (8K) or HFR (4K120) displays, using uncompressed pixel formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the "interesting" modes would be disabled, leaving only low-res or low framerate modes. This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS clock is exceeded. Verified that 8K30 and 4K120 are now available and working with a Samsung Q900R over an HDMI 2.0b link from a Radeon 5700.
