      [MIPS] Reimplement clear_page/copy_page · fb2a27e7
      Thiemo Seufer authored
      Fold the SB-1 specific implementation of clear_page/copy_page in the
      generic version, and rewrite that one in tlbex style. The immediate
      benefits:
        - It converts the compile-time workaround for SB-1 pass 1 prefetches
          to a more efficient run-time check.
        - It allows adjustment of loop unfolling, which helps to reduce the
          number of redundant cdex cache ops.
        - It fixes some esoteric cornercases (the cache line length calculations
          can go wrong, and support for 64k pages without prefetch instructions
          will overflow the addiu immediate).
        - Somewhat better guesses of "good" prefetch values.

      [MIPS] Split the micro-assembler from tlbex.c. · e30ec452
      Thiemo Seufer authored
      This patch moves the micro-assembler in a separate implementation, as
      it is useful for further run-time optimizations. The only change in
      behaviour is cutting down printk noise at kernel startup time.
      
      Checkpatch complains about macro parameters which aren't protected by
      parentheses. I believe this is a flaw in checkpatch, the paste operator
      used in those macros won't work with parenthesised parameters.
