  Log:
  MI changes:
   - provide an interface (macros) to the page coloring part of the VM system,
     this allows to try different coloring algorithms without the need to
     touch every file [1]
   - make the page queue tuning values readable: sysctl vm.stats.pagequeue
   - autotuning of the page coloring values based upon the cache size instead
     of options in the kernel config (disabling of the page coloring as a
     kernel option is still possible)
  
  MD changes:
   - detection of the cache size: only IA32 and AMD64 (untested) contains
     cache size detection code, every other arch just comes with a dummy
     function (this results in the use of default values like it was the
     case without the autotuning of the page coloring)
   - print some more info on Intel CPU's (like we do on AMD and Transmeta
     CPU's)
  
  Note to AMD owners (IA32 and AMD64): please run "sysctl vm.stats.pagequeue"
  and report if the cache* values are zero (= bug in the cache detection code)
  or not.
