It first extends iomem resource interface to support checking a NVDIMM region. Patch 1/3 changes region_intersects() to accept non-RAM regions, and adds region_intersects_ram(). Patch 2/3 adds region_intersects_pmem() to check a NVDIMM region. Patch 3/3 changes the EINJ driver to allow injecting a memory error to NVDIMM. --- v3: - Check the param2 value before target memory type. (Tony Luck) - Add a blank line before if-statement. Remove an unnecessary brakets. (Borislav Petkov) v2: - Change the EINJ driver to call region_intersects_ram() for checking RAM with a specified size. (Dan Williams) - Add export to region_intersects_ram(). --- Toshi Kani (3): 1/3 resource: Add @flags to region_intersects() 2/3 resource: Add region_intersects_pmem() 3/3 ACPI/APEI/EINJ: Allow memory error injection to NVDIMM --- drivers/acpi/apei/einj.c | 12 ++++++++---- include/linux/mm.h | 5 ++++- kernel/memremap.c | 5 ++--- kernel/resource.c | 35 ++++++++++++++++++++++++++++------- 4 files changed, 42 insertions(+), 15 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
