[PATCH v3 0/3] Allow EINJ to inject memory error to NVDIMM

[Toshi Kani]

This patch-set extends the EINJ driver to allow injecting a memory
error to NVDIMM.  It first extends iomem resource interface to support
checking a NVDIMM region.

Patch 1/3 changes region_intersects() to accept non-RAM regions, and
adds region_intersects_ram().

Patch 2/3 adds region_intersects_pmem() to check a NVDIMM region.

Patch 3/3 changes the EINJ driver to allow injecting a memory error
to NVDIMM.
