      BUG#33583 - Falcon memory parameters on 32bit system can be set > 4GB
      
      Fixed that falcon_page_cache_size can be set to value bigger than
      maximum addressable memory.
      
      With this fix, if falcon_page_cache_size is set to bigger than
      maximum addressable memory, it's value is adjusted to maximum
      addressable memory and a warning is issued to the error log.
