      iscsi-target: fix iscsit_del_np deadlock on unload · 81a9c5e7
      Mikulas Patocka authored
      On uniprocessor preemptible kernel, target core deadlocks on unload. The
      following events happen:
      * iscsit_del_np is called
      * it calls send_sig(SIGINT, np->np_thread, 1);
      * the scheduler switches to the np_thread
      * the np_thread is woken up, it sees that kthread_should_stop() returns
        false, so it doesn't terminate
      * the np_thread clears signals with flush_signals(current); and goes back
        to sleep in iscsit_accept_np
      * the scheduler switches back to iscsit_del_np
      * iscsit_del_np calls kthread_stop(np->np_thread);
      * the np_thread is waiting in iscsit_accept_np and it doesn't respond to
      The deadlock could be resolved if the administrator sends SIGINT signal to
      the np_thread with killall -INT iscsi_np
      The reproducible deadlock was introduced in commit
      , but the thread-stopping code was
      racy even before.
      This patch fixes the problem. Using kthread_should_stop to stop the
      np_thread is unreliable, so we test np_thread_state instead. If
      np_thread_state equals ISCSI_NP_THREAD_SHUTDOWN, the thread exits.

      Fix 32-bit regression in block device read(2) · 0b86dbf6
      Al Viro authored
      blkdev_read_iter() wants to cap the iov_iter by the amount of data
      remaining to the end of device.  That's what iov_iter_truncate() is for
      (trim iter->count if it's above the given limit).  So far, so good, but
      the argument of iov_iter_truncate() is size_t, so on 32bit boxen (in
      case of a large device) we end up with that upper limit truncated down
      to 32 bits *before* comparing it with iter->count.
      Easily fixed by making iov_iter_truncate() take 64bit argument - it does
      the right thing after such change (we only reach the assignment in there
      when the current value of iter->count is greater than the limit, i.e.
      for anything that would get truncated we don't reach the assignment at
      all) and that argument is not the new value of iter->count - it's an
      upper limit for such.
      The overhead of passing u64 is not an issue - the thing is inlined, so
      callers passing size_t won't pay any penalty.

      ALSA: hda - restore BCLK M/N values when resuming HSW/BDW display controller · a07187c9
      Mengdong Lin authored
      For Intel Haswell/Broadwell display HD-A controller, the 24MHz HD-A link BCLK
      is converted from Core Display Clock (CDCLK): BCLK = CDCLK * M / N
      And there are two registers EM4 and EM5 to program M, N value respectively.
      The EM4/EM5 values will be lost and when the display power well is disabled.
      BIOS programs CDCLK selected by OEM and EM4/EM5, but BIOS has no idea about
      display power well on/off at runtime. So the M/N can be wrong if non-default
      CDCLK is used when the audio controller resumes, which results in an invalid
      BCLK and abnormal audio playback rate. So this patch saves and restores valid
      M/N values on controller suspend/resume.
      And 'struct hda_intel' is defined to contain standard HD-A 'struct azx' and
      Intel specific fields, as Takashi suggested.
