      ACPI: Execute _PTS before system reboot · 2c85025c
      Ocean He authored
      The _PTS control method is defined in the section 7.4.1 of acpi 6.0
      spec. The _PTS control method is executed by the OS during the sleep
      transition process for S1, S2, S3, S4, and for orderly S5 shutdown.
      
      The _PTS control method provides the BIOS a mechanism for performing
      some housekeeping, such as writing the sleep type value to the embedded
      controller, before entering the system sleeping state. Note that some
      Lenovo Server BIOS use this mechanism to detect reboot event and
      prompt user by popped dialog box.
      
      According to section 7.5 of acpi 6.0 spec, _PTS should run after _TTS.
      Add a _PTS evaulation to the existing _TTS reboot notifier and change
      the notifier name to reflect the fact that it's not for _TTS only any
      more.

      Pull SCSI fixes from James Bottomley:
       "Two straightforward fixes.
      
        One is a concurrency issue only affecting SAS connected SATA drives,
        but which could hang the storage subsystem if it triggers (because the
        outstanding command count on error never goes back to zero) and the
        other is a NO_TAG fallout from the switch to hostwide tags which
        causes the system to crash on module insertion (we've checked
        carefully and only the 53c700 family of drivers is vulnerable to this
        issue)"
