As suggested by Catalin here's the change to add Coresight to defconfig.
Unfortunately I don't think we should add CONFIG_CORESIGHT_SOURCE_ETM4X which builds a few files until [1] is merged because of the overhead of CONFIG_PID_IN_CONTEXTIDR.

James Clark (1): arm64: defconfig: Add Coresight as module
arch/arm64/configs/defconfig | 9 +++++++++ 1 file changed, 9 insertions(+)
Add Coresight to defconfig so that build errors are caught. CONFIG_CORESIGHT_SOURCE_ETM4X is excluded because it depends on CONFIG_PID_IN_CONTEXTIDR which has a performance cost.
