IORESOURCE_SYSTEM_RAM has IORESOURCE_MEM bit set for backward compatibility. - Patch 3 adds a new field, I/O resource descriptor, in 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 adds a check to checkpatch.pl to warn on new use of walk_iomem_res(). - Patch 16 changes the EINJ driver to allow injecting a memory error to NVDIMM. --- 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.
