Subject: x86-64 NODES_SHIFT compile failure.

4323838215184f5a2f081e0d17b8d60731b03164 added this line to x86's Kconfig..

 config NODES_SHIFT
        int
+       range 1 15  if X86_64
        default "6" if X86_64
        default "4" if X86_NUMAQ
        default "3"

Selecting 15 causes:

drivers/base/node.c: In function ‘node_read_distance’:
drivers/base/node.c:140: error: size of array ‘type name’ is negative

Should the upper limit be reduced to 14 (which compiles), or should
the BUILD_BUG_ON be changed to somehow cope with this set of changes?

	Dave
