From 24a9c54182b3758801b8ca6c8c237cc2ff654732 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 8 Jun 2022 16:40:24 +0200 Subject: context_tracking: Split user tracking Kconfig Context tracking is going to be used not only to track user transitions but also idle/IRQs/NMIs. The user tracking part will then become a separate feature. Prepare Kconfig for that.
