      microblaze: Lockdep support · bf2d8096
      Michal Simek 提交于
      Microblaze needs to do lock_init very soon because MMU init calls lock functions.
      
      Here is the explanation from Peter Zijlstra why we have to enable
      __ARCH_WANTS_INTERRUPTS_ON_CTSW.
      
      "So we schedule while holding rq->lock (for obvious reasons), but since
      lockdep tracks held locks per tasks, we need to transfer the held state
      from the prev to the next task. We do this by explicity calling
      spin_release(&rq->lock) in context_switch() right before switch_to(),
      and calling spin_acquire(&rq->lock) in
      finish_task_switch()->finish_lock_switch().
      
      Now, for some reason lockdep thinks that interrupts got enabled over the
      context switch (git grep __ARCH_WANTS_INTERRUPTS_ON_CTSW arch/microblaze
      doesn't seem to turn up anything).
      
      Clearly trying to acquire the rq->lock with interrupts enabled is a bad
      idea and lockdep warns you about this."

      microblaze: Stack trace support · 24b45a12
      Michal Simek 提交于
      This is working implemetation but the problem is that
      Microblaze misses frame pointer that's why is there
      big loop which trace and show all addresses which are in text.
      It shows addresses which are in registers, etc.
      
      This is problem and this is the reason why all Microblaze
      traces are wrong. There is an option to do hacks and trace
      the kernel code but this is too complicated.

      [BKL] add 'might_sleep()' to the outermost lock taker · f01eb364
      Linus Torvalds 提交于
      As shown by the previous patch (6698e347: "tty: Fix BKL taken under a
      spinlock bug introduced in the BKL split") the BKL removal is prone to
      some subtle issues, where removing the BKL in one place may in fact make
      a previously nested BKL call the new outer call, and then prone to nasty
      deadlocks with other spinlocks.
      
      In general, we should never take the BKL while we're holding a spinlock,
      so let's just add a "might_sleep()" to it (even though the BKL doesn't
      technically sleep - at least not yet), and we'll get nice warnings the
      next time this kind of problem happens during BKL removal.

      Alan Cox 提交于
      The fasync path takes the BKL (it probably doesn't need to in fact)
      while holding the file_list spinlock.  You can't do that with the kernel
      lock: it causes lock inversions and deadlocks.
      
      Leave the BKL over that bit for the moment.
