      [SCSI] pm8001: deficient responses to IO_XFER_ERROR_BREAK and IO_XFER_OPEN_RETRY_TIMEOUT · 5954d738
      Mark Salyzyn authored
      IO_XFER_ERROR_BREAK and IO_XFER_OPEN_RETRY_TIMEOUT are deficient of the
      required actions as outlined in the programming manual for the pm8001. Due to
      the overlapping code requirements of these recovery responses, we found it
      necessary to bundle them together into one patch.
      
      When a break is received during the command phase (ssp_completion), this is a
      result of a timeout or interruption on the bus. Logic suggests that we should
      retry the command.
      
      When a break is received during the data-phase (ssp_event), the task must be
      aborted on the target or it will retain a data-phase lock turning the target
      reticent to all future media commands yet will successfully respond to TUR,
      INQUIRY and ABORT leading eventually to target failure through several
      abort-cycle loops.
      
      The open retry interval is exceedingly short resulting in occasional target
      drop-off during expander resets or when targets push-back during bad-block
      remapping. Increased effective timeout from 130ms to 1.5 seconds for each try
      so as to trigger after the administrative inquiry/tur timeout in the scsi
      subsystem to keep error-recovery harmonics to a minimum.
      
      When an open retry timeout event is received, the action required by the
      targets is to issue an abort for the outstanding command then logic suggests
      we retry the command as this state is usually an indication of a credit block
      or busy condition on the target.
      
      We hijacked the pm8001_handle_event work queue handler so that it will handle
      task as an argument instead of device for the workers in support of the
      deferred handling outlined above.

      [SCSI] pm8001: Add FUNC_GET_EVENTS · d95d0001
      Mark Salyzyn authored
      Jack noticed I dropped a patch fragment associated with a flags automatic
      variable in mpi_set_phys_g3_with_ssc (ooops) and that the pre-emptive locking
      that piggy-backed this patch was not in-fact necessary because of underlying
      atomic accesses to the hardware. Here is the updated patch fixing these two
      issues.
      
      The pm8001 driver is missing the FUNC_GET_EVENTS handler in the phy control
      function. Since the pm8001_bar4_shift function was not designed to be called
      at runtime, added locking surrounding the adjustment for all accesses.

      [SCSI] pm8001: fix lockup on phy_control hard reset. · 5c4fb76a
      Mark Salyzyn authored
      pm8001_phy_control PHY_FUNC_HARD_RESET locks up on second try via
      smp_phy_control because response HW_EVENT_PHY_START_STATUS fails to complete
      previous command. The PM8001F_RUN_TIME flag is not treated as a bit, but a
      state in all readers, yet once we are operational or in the run time state,
      the flags use a bit-set operation.

      Says Jens:
      
       "Time to push off some of the pending items.  I really wanted to wait
        until we had the regression nailed, but alas it's not quite there yet.
        But I'm very confident that it's "just" a missing expire on exit, so
        fix from Tejun should be fairly trivial.  I'm headed out for a week on
        the slopes.
      
        - Killing the barrier part of mtip32xx.  It doesn't really support
          barriers, and it doesn't need them (writes are fully ordered).
      
        - A few fixes from Dan Carpenter, preventing overflows of integer
          multiplication.
      
        - A fixup for loop, fixing a previous commit that didn't quite solve
          the partial read problem from Dave Young.
      
        - A bio integer overflow fix from Kent Overstreet.
      
        - Improvement/fix of the door "keep locked" part of the cdrom shared
          code from Paolo Benzini.
      
        - A few cfq fixes from Shaohua Li.
      
        - A fix for bsg sysfs warning when removing a file it did not create
          from Stanislaw Gruszka.
      
        - Two fixes for floppy from Vivek, preventing a crash.
      
        - A few block core fixes from Tejun.  One killing the over-optimized
          ioc exit path, cleaning that up nicely.  Two others fixing an oops
          on elevator switch, due to calling into the scheduler merge check
          code without holding the queue lock."

      block: fix lockdep warning on io_context release put_io_context() · d8c66c5d
      Tejun Heo authored
      11a3122f "block: strip out locking optimization in put_io_context()"
      removed ioc_lock depth lockdep annoation along with locking
      optimization; however, while recursing from put_io_context() is no
      longer possible, ioc_release_fn() may still end up putting the last
      reference of another ioc through elevator, which wlil grab ioc->lock
      triggering spurious (as the ioc is always different one) A-A deadlock
      warning.
      
      As this can only happen one time from ioc_release_fn(), using non-zero
      subclass from ioc_release_fn() is enough.  Use subclass 1.

      Staging tree patches for 3.3-rc3
      
      Big things here is the deletion of the Android pmem driver, as it's
      obsolete and no one uses it, the gma500 driver as it's already in the
      drm portion of the kernel tree, and the pohmelfs filesystem as it's
      obsolete and a rewritten version is being proposed for the fs/ section
      of the kernel.
      
      Other than that, a smattering of different bugfixes and regressions, and
      some omap drm api merge fixups that were needed due to api changes in
      the main portion of the drm tree, allowing this code to build properly
      again.
