      i915: temporary fix for DP MST docking station NULL pointer dereference · 27667f47
      Linus Torvalds authored
      Ted Ts'o reports that his Lenovo T540p ThinkPad crashes at boot if
      attached to the docking station.  This is a regression that he was able
      to bisect to commit 8c7b5ccb: "drm/i915: Use atomic helpers for
      computing changed flags:"
      
      The reason seems to be the new call to drm_atomic_helper_check_modeset()
      added to intel_modeset_compute_config(), which in turn calls
      update_connector_routing(), and somehow ends up picking a NULL crtc for
      the connector state, causing the subsequent drm_crtc_index() to OOPS.
      
      Daniel Vetter says that the fundamental issue seems to be confusion in
      the encoder selection, and this isn't the right fix, but while he chases
      down the proper fix, this at least avoids the NULL pointer dereference
      and makes Ted's docking station work again.

      link_path_walk(): be careful when failing with ENOTDIR · 97242f99
      Al Viro authored
      In RCU mode we might end up with dentry evicted just we check
      that it's a directory.  In such case we should return ECHILD
      rather than ENOTDIR, so that pathwalk would be retries in non-RCU
      mode.
      
      Breakage had been introduced in commit b18825a7 - prior to that
      we were looking at nd->inode, which had been fetched before
      verifying that ->d_seq was still valid.  That form of check
      would only be satisfied if at some point the pathname prefix
      would indeed have resolved to a non-directory.  The fix consists
      of checking ->d_seq after we'd run into a non-directory dentry,
      and failing with ECHILD in case of mismatch.
      
      Note that all branches since 3.12 have that problem...

      These changes were already validated as part of FSL SDK.
      Patch 2 fixes occasional wake-on magic packet failures during
      traffic, probably due to incorrect traffic stop/ device halt
      sequence and incorrect usage of txlock.

      gianfar: Enable device wakeup when appropriate · b0734b6d
      Claudiu Manoil authored
      The wol_en flag is 0 by default anyway, and we have the
      following inconsistency: a MAGIC packet wol capable eth
      interface is registered as a wake-up source but unable
      to wake-up the system as wol_en is 0 (wake-on flag set to 'd').
      Calling set_wakeup_enable() at netdev open is just redundant
      because wol_en is 0 by default.
      Let only ethtool call set_wakeup_enable() for now.
      
      The bflock is obviously obsoleted, its utility has been corroded
      over time.  The bitfield flags used today in gianfar are accessed
      only on the init/ config path, with no real possibility of
      concurrency - nothing that would justify smth. like bflock.

      gianfar: Fix suspend/resume for wol magic packet · 614b4242
      Claudiu Manoil authored
      If we disable NAPI in the first place we can mask the device's
      interrupts (and halt it) without fearing that imask may be
      concurrently accessed from interrupt context, so there's
      no need to do local_irq_save() around gfar_halt_nodisable().
      lock_rx_qs()/unlock_tx_qs() are just obsoleted and potentially
      buggy routines.  The txlock is currently used in the driver only
      to manage TX congestion, it has nothing to do with halting the
      device.  With these changes, the TX processing is stopped before
      gfar_halt().
      
      Compact gfar_halt() is used instead of gfar_halt_nodisable(),
      as it disables Rx/TX DMA h/w blocks and the Rx/TX h/w queues.
      gfar_start() re-enables all these blocks on resume.  Enabling
      the magic-packet mode remains the same, note that the RX block
      is re-enabled just before entering sleep mode.
      
      Add IRQF_NO_SUSPEND flag for the error interrupt line, to signal
      that the interrupt line must remain active during sleep in order
      to wake the system by magic packet (MAG) reception interrupt.
      (On some systems the MAG interrupt did trigger w/o this flag
      as well, but on others it didn't.)
      
      Without these fixes, when suspended during fair Tx traffic the
      interface occasionally failed to be woken up by magic packet.

      ARM: dts: keystone: fix dt bindings to use post div register for mainpll · c1bfa985
      Murali Karicheri authored
      All of the keystone devices have a separate register to hold post
      divider value for main pll clock. Currently the fixed-postdiv
      value used for k2hk/l/e SoCs works by sheer luck as u-boot happens to
      use a value of 2 for this. Now that we have fixed this in the pll
      clock driver change the dt bindings for the same.

      Pull IOMMU fixes from Joerg Roedel:
       "These fixes are all for the AMD IOMMU driver:
      
         - A regression with HSA caused by the conversion of the driver to
           default domains.  The fixes make sure that an HSA device can still
           be attached to an IOMMUv2 domain and that these domains also allow
           non-IOMMUv2 capable devices.
      
         - Fix iommu=pt mode which did not work because the dma_ops where set
           to nommu_ops, which breaks devices that can only do 32bit DMA.
      
         - Fix an issue with non-PCI devices not working, because there are no
           dma_ops for them.  This issue was discovered recently as new AMD
           x86 platforms have non-PCI devices too"

      Revert "dmaengine: virt-dma: don't always free descriptor upon completion" · 8c8fe97b
      Jun Nie authored
      This reverts commit b9855f03.
      The patch break existing DMA usage case. For example, audio SOC
      dmaengine never release channel and cause virt-dma to cache too
      much memory in descriptor to exhaust system memory.
