      drm/msm: Remove __user from __u64 data types · cdbc78ba
      Jordan Crouse authored
      __user should be used to identify user pointers and not __u64
      variables containing pointers.

      drm/msm: args->fence should be args->flags · b0135ab9
      Jordan Crouse authored
      Fix a typo in msm_ioctl_gem_submit - check args->flags for the
      MSM_SUBMIT_NO_IMPLICIT flag instead of args->fence.

      drm/msm: Turn off hardware clock gating before reading A5XX registers · a23cb3b5
      Jordan Crouse authored
      On A5XX GPU hardware clock gating needs to be turned off before
      reading certain GPU registers via AHB. Turn off HWCG before calling
      adreno_show() to safely dump all the registers without a system hang.

      drm/msm: Allow hardware clock gating to be toggled · 6e749e59
      Jordan Crouse authored
      There are some use cases wherein we need to turn off hardware clock
      gating before reading certain registers. Modify the A5XX HWCG function
      to allow user to enable or disable clock gating at will.

      drm/msm: Remove some potentially blocked register ranges · 3394f561
      Jordan Crouse authored
      The 0xf400 and 0xf800 ranges are in the RBBM_SECVID block which may
      be protected from CPU access. Skip dumping them since they are minimally
      useful for debugging and they aren't worth a system hang.

      drm/msm/mdp5: Drop clock names with "_clk" suffix · d0538f50
      Archit Taneja authored
      We have upstream bindings (msm8916) that have the "_clk" suffix in the
      clock names. The downstream bindings also require it.
      
      We want to drop the "_clk" suffix and at the same time support existing
      bindings. Update the MDP5 code with the the msm_clk_get() helper to
      support both old and new clock names.

      drm/msm/mdp5: Fix typo in encoder_enable path · b0e77fd8
      Archit Taneja authored
      The mdp5_cmd_encoder_disable is accidentally called in the encoder enable
      path. We've not seen any problems since we haven't tested with command
      mode panels in a while. Fix the copy-paste error.

      drm/msm/dsi: Calculate link clock rates with updated dsi->lanes · d4cea38e
      Archit Taneja authored
      After the commit mentioned below, we start computing the byte and pixel
      clocks (dsi_calc_clk_rate) in the DSI bridge's mode_set() op. The
      calculation involves the number of DSI lanes being used by the
      downstream bridge/panel.
      
      If the downstream bridge/panel tries to change the number of DSI lanes
      (as done in the ADV7533 driver) in its mode_set() op, then our DSI
      host driver will not have the correct number of lanes when computing
      byte/pixel clocks.
      
      Fix this by delaying the clock rate calculation in the DSI bridge
      enable path. In particular, compute the clock rates in
      msm_dsi_host_get_phy_clk_req().
      
      This fixes the DSI host error interrupts seen when we try to switch
      between modes that require different number of lanes (4 to 3 lanes, or
      vice versa) on db410c. The error interrupts occur since the byte/pixel
      clock rates aren't according to what the DSI video mode timing engine
      expects.

      drm/msm: fix an integer overflow test · 65e93108
      Dan Carpenter authored
      We recently added an integer overflow check but it needs an additional
      tweak to work properly on 32 bit systems.
      
      The problem is that we're doing the right hand side of the assignment as
      type unsigned long so the max it will have an integer overflow instead
      of being larger than SIZE_MAX.  That means the "sz > SIZE_MAX" condition
      is never true even on 32 bit systems.  We need to first cast it to u64
      and then do the math.

      Fix them by adding another pair of {}.

      NFSv4.1: Fix a race where CB_NOTIFY_LOCK fails to wake a waiter · b7dbcc0e
      Benjamin Coddington authored
      nfs4_retry_setlk() sets the task's state to TASK_INTERRUPTIBLE within the
      same region protected by the wait_queue's lock after checking for a
      notification from CB_NOTIFY_LOCK callback.  However, after releasing that
      lock, a wakeup for that task may race in before the call to
      freezable_schedule_timeout_interruptible() and set TASK_WAKING, then
      freezable_schedule_timeout_interruptible() will set the state back to
      TASK_INTERRUPTIBLE before the task will sleep.  The result is that the task
      will sleep for the entire duration of the timeout.
      
      Since we've already set TASK_INTERRUPTIBLE in the locked section, just use
      freezable_schedule_timout() instead.

      lightnvm: pblk: advance bio according to lba index · 75cb8e93
      Javier González authored
      When a lba either hits the cache or corresponds to an empty entry in the
      L2P table, we need to advance the bio according to the position in which
      the lba is located. Otherwise, we will copy data in the wrong page, thus
      causing data corruption for the application.
      
      In case of a cache hit, we assumed that bio->bi_iter.bi_idx would
      contain the correct index, but this is no necessarily true. Instead, use
      the local bio advance counter and iterator. This guarantees that lbas
      hitting the cache are copied into the right bv_page.
      
      In case of an empty L2P entry, we omitted to advance the bio. In the
      cases when the same I/O also contains a cache hit, data corresponding
      to this lba will be copied to the wrong bv_page. Fix this by advancing
      the bio as we do in the case of a cache hit.

      arm64: mmu: Place guard page after mapping of kernel image · 92bbd16e
      Will Deacon authored
      The vast majority of virtual allocations in the vmalloc region are followed
      by a guard page, which can help to avoid overruning on vma into another,
      which may map a read-sensitive device.
      
      This patch adds a guard page to the end of the kernel image mapping (i.e.
      following the data/bss segments).
