It appears that only patch 4 has been picked up?
(I'm on next-20190401)

$ git ls --grep='arm64: dts: qcom: sdm845: Add Coresight support' --grep='arm64: dts: qcom: msm8996: Add Coresight support' --grep='arm64: dts: qcom: msm8998: Add Coresight support' --grep='coresight: etm4x: Add support to enable ETMv4.2' --grep='coresight: etm4x: Add ETM PIDs for SDM845 and MSM8996' --grep='coresight: cpu-debug: Add support for Qualcomm Kryo'

5666dfd1d8a4 coresight: etm4x: Add support to enable ETMv4.2

Bjorn, I think the arch/arm64/boot/dts/qcom patches are for you?

Mathieu/Suzuki, the remaining 2 would be for you?
