I have applied this set.

Mathieu -- the plan here (which we have discussed on the list [1]) is for the first four patches to be shared with arm64. Since you've gone ahead and applied the whole series, please can you provide me a stable branch with the first four patches only so that I can include them in the arm64 tree?

Failing that, I can create a branch for you to pull and apply the remaining patches on top.

Please let me know.

Coresight patches flow through Greg's tree and as such the coresight-next tree gets rebased anyway. I will remove the first 4 patches and push again. By the way do you also want to pick up patches 14 and 16 since they are concerned with "arch/arm64/Kconfig" or should I keep them?

Thanks, Mathieu

Thanks,

Will
