    Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
    
    Pull arm64 fixes from Will Deacon:
     "This addresses some problems with filesystem writeback due to the
      recently merged hardware DBM patches, which caused us to treat some
      read-only pages as dirty.
    
      There are also some other, less significant fixes that are described
      in the summary below:
    
      A mixture of fixes for regressions introduced during the merge window,
      some longer standing problems that we spotted and a couple of hardware
      errata.  The main changes are:
    
       - Fix fallout from the h/w DBM patches, causing filesystem writeback
         issues on both v8 and v8.1 CPUs
    
       - Workaround for Cortex-A53 erratum #843419 in the module loader
    
       - Fix for long-standing issue with compat big-endian signal handlers
         using the saved floating point state"
