[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.
