      sh: Migrate from PG_mapped to PG_dcache_dirty. · 2277ab4a
      Paul Mundt authored
      This inverts the delayed dcache flush a bit to be more in line with other
      platforms. At the same time this also gives us the ability to do some
      more optimizations and cleanup. Now that the update_mmu_cache() callsite
      only tests for the bit, the implementation can gradually be split out and
      made generic, rather than relying on special implementations for each of
      the peculiar CPU types.
      
      SH7705 in 32kB mode and SH-4 still need slightly different handling, but
      this is something that can remain isolated in the varying page copy/clear
      routines. On top of that, SH-X3 is dcache coherent, so there is no need
      to bother with any of these tests in the PTEAEX version of
      update_mmu_cache(), so we kill that off too.

      sh: Provide _PAGE_SPECIAL for 32-bit. · c0b96cf6
      Paul Mundt authored
      Allocate one of the unused PTE bits for _PAGE_SPECIAL directly. This is
      prep work for fast gup and the zero page revival.
