For QEMU emulated devices, nfit drivers need not be loaded, also the
nfit_test, libnvdimm_test modules are not required. This patch adds a
configure option to enable testing on qemu without nfit dependencies.

You are invited to propose a presentation at the first annual Persistent
Programming in Real Life (PIRL) (https://pirl.nvsl.io/). PIRL brings
together software development leaders interested in learning about
programming methodologies for persistent memories (e.g. NVDIMMs, Optane DC)
and sharing
When inserting entry into xarray, we store mapping and index in
corresponding struct pages for memory error handling. When it happened
that one process was mapping file at PMD granularity while another
process at PTE granularity, we could wrongly deassociate PMD range and
then reassociate PTE

The GUP fast argument passing is a mess.
