Marco Elver 92c209ac6d kcsan: Improve IRQ state trace reporting ... To improve the general usefulness of the IRQ state trace events with KCSAN enabled, save and restore the trace information when entering and exiting the KCSAN runtime as well as when generating a KCSAN report. Without this, reporting the IRQ trace events (whether via a KCSAN report or outside of KCSAN via a lockdep report) is rather useless due to continuously being touched by KCSAN. This is because if KCSAN is enabled, every instrumented memory access causes changes to IRQ trace events (either by KCSAN disabling/enabling interrupts or taking report_lock when generating a report). Before "lockdep: Prepare for NMI IRQ state tracking", KCSAN avoided touching the IRQ trace events via raw_local_irq_save/restore() and lockdep_off/on().
