I include some demo programs:

test/ph.c:      migrates some of its pages by use of their physical addresses
test/v.c:       migrates a part of its virtual address range
test/vmig.c:    migrates a part of the virtual address range of "test/victim.c"
test/migstat.c: displays some internal counters if the kernel has been compiled
                with "_NEED_STATISTICS_" defined

They are not too much portable, many hard coded numbers,...
