  [MIPS] Make facility to convert CPU types to strings generally available.
  [MIPS] Convert list of CPU types from #define to enum.
  [MIPS] Optimize get_unaligned / put_unaligned implementations.
  [MIPS] checkfiles: Fix "need space after that ','" errors.
  [MIPS] Fix "no space between function name and open parenthesis" warnings.
  [MIPS] Allow hardwiring of the CPU type to a single type for optimization.
  [MIPS] tlbex: Size optimize code by declaring a few functions inline.
  [MIPS] pg-r4k.c: Dump the generated code
  [MIPS] Cobalt: Remove cobalt_machine_power_off()
