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.
