      There are multiple ingredients for this:
      
       1) PAGE_NONE is defined to _CACHE_CACHABLE_NONCOHERENT, which is CCA 3
          on all platforms except SB1 where it's CCA 5.
       2) _page_cachable_default must have bits set which are not set
          _CACHE_CACHABLE_NONCOHERENT.
       3) Either the defective version of pte_modify for XPA or the standard
          version must be in used.  However pte_modify for the 36 bit address
          space support is no affected.
      
      In that case additional bits in the final CCA mode may generate an invalid
      value for the CCA field.  On the R10000 system where this was tracked
      down for example a CCA 7 has been observed, which is Uncached Accelerated.
      
      Fixed by:
      
       1) Using the proper CCA mode for PAGE_NONE just like for all the other
          PAGE_* pte/pmd bits.
       2) Fix the two affected variants of pte_modify.
      
      Further code inspection also shows the same issue to exist in pmd_modify
      which would affect huge page systems.
      
      Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE
      and pmd_modify issue found by me.
      
      The history of this goes back beyond Linus' git history.  Chris Dearman's
      commit 35133692 ("[MIPS] Allow setting of
      the cache attribute at run time.") missed the opportunity to fix this
      but it was originally introduced in lmo commit
      d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.")
      and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option
      CONFIG_MIPS_UNCACHED.")
