      arm64: dts: mark lx2160a esdhc controllers dma coherent · 62b4359c
      Russell King authored
      The LX2160A esdhc controllers are setup by the driver to be DMA
      coherent, but without marking them as such in DT, Linux thinks they
      are not.  This can lead to random sporadic DMA errors, even to the
      extent of preventing boot, such as:

      These are caused by the device's descriptor fetch hitting speculatively
      loaded CPU cache lines that the CPU does not see through the normal,
      non-cacheable DMA coherent mapping that it uses for non-coherent
      devices.
      
      DT and the device must agree wrt whether the device is DMA coherent or
      not.

      Pull btrfs fixes from David Sterba:
       "A bunch of fixes that accumulated in recent weeks, mostly material for
        stable.
      
        Summary:
      
         - fix for regression from 5.3 that prevents to use balance convert
           with single profile
      
         - qgroup fixes: rescan race, accounting leak with multiple writers,
           potential leak after io failure recovery
      
         - fix for use after free in relocation (reported by KASAN)
      
         - other error handling fixups"
