Say Y to compile the kernel with support for a virtual mem map.
This is an alternate method of supporting large holes in the
physical address space on non NUMA machines. Since the DISCONTIGMEM
option is not supported on machines with the ZX1 chipset, this is
the only way of supporting more than 1 Gb of memory on those
machines. This code also only takes effect if a memory hole of
greater than 1 Gb is found during boot, so it is safe to enable
unless you require the DISCONTIGMEM option for your machine. If you
are unsure, say Y.
