Subject[PATCH v3 00/17] Enhance iomem search interfaces and support EINJ to NVDIMM
Date
This patch-set enhances the iomem table and its search interfacs, and
then changes EINJ to support NVDIMM.

- Patches 1-2 add a new System RAM type, IORESOURCE_SYSTEM_RAM, and
make the iomem search interfaces work with resource flags with
modifier bits set. IORESOURCE_SYSTEM_RAM has IORESOURCE_MEM bit set
for backward compatibility.

- Patch 3 adds a new field, I/O resource descriptor, into struct resource.
Drivers can assign their unique descritor to a range when they support
the iomem search interfaces.

- Patches 4-9 changes initializations of resource entries. They set
the System RAM type to System RAM ranges, set I/O resource descriptors
to the regions targeted by the iomem search interfaces, and change
to call kzalloc() where kmalloc() is used to allocate struct resource
ranges.

- Patches 10-14 extend the iomem interfaces to check System RAM ranges
with the System RAM type and the I/O resource descriptor.

- Patch 15-16 remove deprecated walk_iomem_res().

- Patch 17 changes the EINJ driver to allow injecting a memory error
to NVDIMM.

---
v3:
- Remove the walk_iomem_res() call with "GART" in crash.c since it is
no longer needed. Then kill walk_iomem_res(). (Borislav Petkov,
Dave Young)
- Change to use crashk_res.desc at the walk_iomem_res_desc() call in
kexec_add_buffer(). (Minfei Huang)

v2:
- Add 'desc' to struct resource, and add a new iomem interface to
search with the desc. (Borislav Petkov)
- Add a check to checkpatch.pl to warn on new use of walk_iomem_res().
(Borislav Petkov)

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 needs to be able to distinguish legacy and NFIT pmem
ranges. (Dan Williams)
