[PATCH] x86-64: x86_64-make-the-numa-hash-function-nodemap-allocation fix fix

- Removed an extraneous debug message from allocate_cachealigned_map

- Changed extract_lsb_from_nodes to return 63 for the case where there was
  only one memory node.  The prevents the creation of the dynamic hashmap.

- Changed extract_lsb_from_nodes to use only the starting memory address of
  a node.  On an ES7000, our nodes overlap the starting and ending address,
  meaning, that we see nodes like

	00000 - 10000
	10000 - 20000

  But other systems have nodes whose start and end addresses do not overlap.
   For example:

	00000 - 0FFFF
	10000 - 1FFFF

  In this case, using the ending address will result in an LSB much lower
  than what is possible.  In this case an LSB of 1 when in reality it should
  be 16.
