  Log:
  Add a vm.blacklist tunable which can hold a space or comma seperated list
  of physical addresses.  The pages containing these physical addresses will
  not be added to the free list and thus will effectively be ignored by the
  VM system.  This is mostly useful for the case when one knows of specific
  physical addresses that have bit errors (such as from a memtest run) so
  that one can blacklist the bad pages while waiting for the new sticks of
  RAM to arrive.  The physical addresses of any ignored pages are listed in
  the message buffer as well.
