[Xen-devel] [PATCH v3 00/17] Enhance iomem search interfaces and support EINJ to NVDIMM

[Toshi Kani <toshi.kani@xxxxxxx>]

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)
