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
