       "Another few ARM fixes.  Fabrice fixed the L2 cache DT parsing to allow

        Laura noticed that the setting of page attributes wasn't working for
        modules due to is_module_addr() always returning false.
      
        Marc Gonzalez (aka Mason) noticed a potential latent bug with the way
        we read one of the CPUID registers (where we could attempt to read a
        non-present CPUID register which may fault.)
      
        I've fixed an issue where 32-bit DMA masks were failing with memory
        which extended to the top of physical address space, and I've also
        added debugging output of the page tables when we hit a data access
        exception which we don't specifically handle - prompted by the lack of

      fuse: explicitly set /dev/fuse file's private_data · 94e4fe2c
      Tom Van Braeckel authored
      The misc subsystem (which is used for /dev/fuse) initializes private_data to
      point to the misc device when a driver has registered a custom open file
      operation, and initializes it to NULL when a custom open file operation has
      *not* been provided.
      
      This subtle quirk is confusing, to the point where kernel code registers
      *empty* file open operations to have private_data point to the misc device
      structure. And it leads to bugs, where the addition or removal of a custom open
      file operation surprisingly changes the initial contents of a file's
      private_data structure.
      
      So to simplify things in the misc subsystem, a patch [1] has been proposed to
      *always* set the private_data to point to the misc device, instead of only
      doing this when a custom open file operation has been registered.
      
      But before this patch can be applied we need to modify drivers that make the
      assumption that a misc device file's private_data is initialized to NULL
      because they didn't register a custom open file operation, so they don't rely
      on this assumption anymore. FUSE uses private_data to store the fuse_conn and
      errors out if this is not initialized to NULL at mount time.
      
      Hence, we now set a file's private_data to NULL explicitly, to be independent
      of whatever value the misc subsystem initializes it to by default.

      use arch_initcall() for the registry.

         - an entry code fix,
      
         - and a VDSO build fix"
