-  numa=fake=CMDLINE
-                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,*128
-                gives two 512M nodes, a 1024M node, four 256M nodes, and the
-                rest split into 128M chunks.  If the last character of CMDLINE
-                is a *, the remaining memory is divided up equally among its
-                coefficient:
-                        numa=fake=2*512,2*
-                gives two 512M nodes and the rest split into two nodes.
-                Otherwise, the remaining system RAM is allocated to an
-                additional node.
