    ARCv2: Enable LOCKDEP · d9676fa1
    Evgeny Voevodin authored
    - The asm helpers for calling into irq tracer were missing
    
    - Add calls to above helpers in low level assembly entry code for ARCv2
    
    - irq_save() uses CLRI to disable interrupts and returns the prev interrupt
      state (in STATUS32) in a specific encoding (and not the raw value of
      STATUS32). This is usable with SETI in irq_restore(). However
      save_flags() reads the raw value of STATUS32 which doesn't pair with
      irq_save/restore() and thus needs fixing.
