Message-Id: <1452020068-26492-1-git-send-email-toshi.kani@hpe.com> Date: Tue, 5 Jan 2016 11:54:28 -0700 From: Toshi Kani <toshi.kani@....com> To: akpm@...ux-foundation.org, bp@...en8.de Cc: torvalds@...ux-foundation.org, rafael.j.wysocki@...el.com, dan.j.williams@...el.com, dyoung@...hat.com, x86@...nel.org, linux-ia64@...r.kernel.org, linux-parisc@...r.kernel.org, linux-sh@...r.kernel.org, kexec@...ts.infradead.org, xen-devel@...ts.xenproject.org, linux-samsung-soc@...r.kernel.org, linux-arch@...r.kernel.org, linux-mm@...ck.org, linux-nvdimm@...ts.01.org, linux-acpi@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v3 00/17] Enhance iomem search interfaces and support EINJ to NVDIMM 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.
