      Currently, when a tape device is set online and no cartridge is loaded, we
      get the messages "The tape cartridge has been successfully unloaded" and
      "Determining the size of the recorded area". These messages are not correct.
      To fix this, we now print the "cartridge loaded/unloaded" messages only,
      when the load/unload event really occurs. In addition to that, the message
      "Determining the size of the recorded area" is only printed, if a cartridge
      is loaded.

      Heiko Carstens authored
      
      
      "lockdep: Fix backtraces" reveales a bug in early setup code: when
      lockdep tries to save a stack backtrace before setup_arch has been
      called the lowcore pointer for the current thread info pointer isn't
      initialized yet.
      However our save stack backtrace code relies on it. If the pointer
      isn't initialized the saved backtrace will have zero entries.
      lockdep however relies (correctly) on the fact that that cannot
      happen.
      A write access to some random memory region is the result.
      
      Fix this by initializing the thread info pointer early.

      [S390] fix recursive locking on page_table_lock · 50aa98ba
      Martin Schwidefsky authored
      
      
      Suzuki Poulose reported the following recursive locking bug on s390:
      
      Here is the stack trace : (see Appendix I for more info)
      
        [<0000000000406ed6>] _spin_lock+0x52/0x94
        [<0000000000103bde>] crst_table_free+0x14e/0x1a4
        [<00000000001ba684>] __pmd_alloc+0x114/0x1ec
        [<00000000001be8d0>] handle_mm_fault+0x2cc/0xb80
        [<0000000000407d62>] do_dat_exception+0x2b6/0x3a0
        [<0000000000114f8c>] sysc_return+0x0/0x8
        [<00000200001642b2>] 0x200001642b2
      
      The page_table_lock is already acquired in __pmd_alloc (mm/memory.c) and
      it tries to populate the pud/pgd with a new pmd allocated. If another
      thread populates it before we get a chance, we free the pmd using
      pmd_free().
      
      On s390x, pmd_free(even pud_free ) is #defined to crst_table_free(),
      which acquires the page_table_lock to protect the crst_table index updates.
      
      Hence this ends up in a recursive locking of the page_table_lock.
      
      The solution suggested by Dave Hansen is to use a new spin lock in the mmu
      context to protect the access to the crst_list and the pgtable_list.
