    kernel - Fix ranging test in memory probe, adjust memory test
    
    * Fix a ranging test in the memory probe code.  The 'incr' value can
      potentially skip over blacked-out areas of memory and thus accidently
      include them in the range.
    
    * We no longer exhaustively test memory.  Instead, just test the first
      and last page for each range.
