This was introduced in the 2025.08.11 SRU cycle, but possibly the only kernel marked supported that uses coresight is the azure-nvidia-6.14 kernel. The patch will be submitted for the generic kernel for cycles going forward, but needs to be applied to azure-nvidia-6.14 during this cycle to allow the kernel to build. It should be dropped from azure- nvidia-6.14 once rebased in a future cycle.

This causes the kernel to fail to build when coresight is enabled. [Fix] * Clean cherry-picks of the following upstream patches: * 3c03c49b2fa5: "Coresight: Introduce a new struct coresight_path" * d87d76d823d1: "Coresight: Allocate trace ID after building the path" * 080ee83cc361: "Coresight: Change functions to accept the coresight_path" [Test Plan] * Compile tested [Regression potential] * Changes are localized to coresight. Possible regressions could result in unexpected behavior of coresight module.
