   numa=noacpi   Don't parse the SRAT table for NUMA setup
 
-  numa=fake=X   Fake X nodes and ignore NUMA setup of the actual machine.
+  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.
