                If a number, fakes CMDLINE nodes and ignores NUMA setup of the
                actual machine.  Otherwise, system memory is configured
                depending on the sizes and coefficients listed.  For example:
-                       numa=fake=2*512,1024,4*256
-               gives two 512M nodes, a 1024M node, and four 256M nodes.  The
-               remaining system RAM is allocated to an additional node.  If
-               the last character of CMDLINE is a *, the remaining system RAM
-               is instead divided up equally among its coefficient.
