Subject: [PATCH 00/11] Support System RAM resource type and EINJ to NVDIMM

This patch-set introduces a new I/O resource type, IORESOURCE_SYSTEM_RAM,
for System RAM while keeping the current IORESOURCE_MEM type bit set for
all memory-mapped ranges (including System RAM) for backward compatibility.
With the new System RAM type, walking through the iomem resource table
no longer requires to test with strcmp() against "System RAM".  After this
infrastructure update, this patch changes EINJ to support NVDIMM.

Patches 1-2 add a new System RAM type, and make resource interfaces work
with resource flags with modifier bits set.

Patches 3-7 set the System RAM type to System RAM ranges.

Patches 8-10 extend resource interfaces to check System RAM ranges with
the System RAM type.

Patch 11 changes the EINJ driver to allow injecting a memory error to
NVDIMM.

v1:
 - Searching for System RAM in the resource table should not require
   strcmp(). (Borislav Petkov)
 - Add a new System RAM type as a modifier to IORESOURCE_MEM.
   (Linus Torvalds)
 - NVDIMM check should remain with strcmp() against "Persistent Memory".
   (Dan Williams)
 - Reset patch version.

prev-v3:
 - Check the param2 value before target memory type. (Tony Luck)
 - Add a blank line before if-statement. Remove an unnecessary brakets.
   (Borislav Petkov)

prev-v2:
 - Change the EINJ driver to call region_intersects_ram() for checking
   RAM with a specified size. (Dan Williams)
