ltp has many weird swap tests

only the file type in the swap signature; since the higher bits in the
pte are used by the non-linear vma feature afaik)
How was the kernel compiled? It must have been running on a NUMA system
for page migration to be enabled. Otherwise the fallback definitions in
include/linux/swapops.h should remove all the swap migration entry
handling.
x86_64 NUMA. Config is here:

mtest01 was what killed it, IIRC.
