[PATCH 1/2] Add module "90nvdimm" for NVDIMM support

[mwilck-IBi9RG/b67k]

From: Martin Wilck <mwilck-IBi9RG/b67k@public.gmane.org>

Detection of persistent memory devices works mostly out of the box
already. Only the "provider" modules for ndbus devices, which are responsible
to extract information of available NVDIMM devices and their configuration
from system firmware, are only indirectly linked into the module stack.
Examples for such modules are nfit.ko, nd_e820.ko, and virtio-pmem.ko.

Add a module that resolves these dependencies.

[PATCH 2/2] 90kernel-modules: remove nfit from static module list

[mwilck-IBi9RG/b67k]

From: Martin Wilck <mwilck-IBi9RG/b67k@public.gmane.org>

The 90nvdimm module now resolves the nfit dependency when it's
necessary, so it's not necessary any more to pack it always.
