2019-10-10drm/amd/display: fix bug with check for HPD Low in verify link capSivapiriyan Kumarasamy
[Why] There is a bug when determining if link training should be retried when HPD is low in dp_verify_link_cap_with_retries. [How] Correctly, fail dp_verify_link_cap_with_retries without retry when HPD is low.

[Why] When the driver sends a pipe set command to the DMCU FW, it does not wait for the command to complete.

2019-10-10SUNRPC: fix race to sk_err after xs_error_reportBenjamin Coddington
Since commit 4f8943f80883 ("SUNRPC: Replace direct task wakeups from softirq context") there has been a race to the value of the sk_err if both XPRT_SOCK_WAKE_ERROR and XPRT_SOCK_WAKE_DISCONNECT are set. In that case, we may end up losing the sk_err value that existed when xs_error_report was called. Fix this by reverting to the previous behavior: instead of using SO_ERROR to retrieve the value at a later time (which might also return sk_err_soft), copy the sk_err value onto struct sock_xprt, and use that value to wake pending tasks.

2019-10-10drm/i915: Move SAGV block time to dev_privJames Ausmus
In prep for newer platforms having more complicated ways to determine the SAGV block time, move the variable to dev_priv, and extract the setting to an initial setup function.

Now that we have the engine stored in i915_perf, we have a means of accessing intel_gt should we require it.

2019-10-10nbd: fix possible sysfs duplicate warningXiubo Li
1. nbd_put takes the mutex and drops nbd->ref to 0. It then does idr_remove and drops the mutex. 2. nbd_genl_connect takes the mutex. idr_find/idr_for_each fails to find an existing device, so it does nbd_dev_add. 3. just before the nbd_put could call nbd_dev_remove or not finished totally, but if nbd_dev_add try to add_disk, we can hit: debugfs: Directory 'nbd1' with parent 'block' already present! This patch will make sure all the disk add/remove stuff are done by holding the nbd_index_mutex lock.

2019-10-10xen: Stop abusing DT of_dma_configure APIRob Herring
As the removed comments say, these aren't DT based devices. of_dma_configure() is going to stop allowing a NULL DT node and calling it will no longer work. The comment is also now out of date as of commit 9ab91e7c5c51 ("arm64: default to the direct mapping in get_arch_dma_ops"). Direct mapping is now the default rather than dma_dummy_ops. According to Stefano and Oleksandr, the only other part needed is setting the DMA masks and there's no reason to restrict the masks to 32-bits. So set the masks to 64 bits.

2019-10-10drm/i915: Remove cursor use of properties for coordinatesMaarten Lankhorst
We have a src and dect rectangle, use it instead of relying on the core drm properties. Because the core by default clips the src/dst properties, after the drm_atomic_helper_check_plane_state() we manually set the unclipped src/dst rectangles. We still need the call for visibility checks, but this way we are able to use the src/dst rects in the check/commit code. This removes the special case in the watermark code for cursor w/h.
