As for the other 3 patches, Patch 1 and Patch 2 will apply cleanly to the right coresight nodes but due to the missing unique context in Patch 3, it could be applied to some other node. We had to upload this change 3 times in chromium tree to get it applied to the right replicator node :) and this property in Patch 3 is important to fix a hard lockup. I'm not sure why this patch is missing the proper context :/ I couldn't find the changes yet in qcom/for-next or other branches to see if it is applied to right replicator node. In case you haven't applied it yet, Patch 3 change should be applied to "replicator@6b06000" node.
