Pull libnvdimm fixes from Dan Williams: - Two fixes for compatibility with the ACPI 6.1 specification. Without these fixes multi-interface DIMMs will fail to be probed, and address range scrub commands to find memory errors will give results that the kernel will mis-interpret. For multi-interface DIMMs Linux will accept either the original 6.0 implementation or 6.1. For address range scrub we'll only support 6.1 since ACPI formalized this DSM differently than the original example [1] implemented in v4.2. The expectation is that production systems will only ever ship the ACPI 6.1 address range scrub command definition. - The wider async address range scrub work targeting 4.6 discovered that the original synchronous implementation in 4.5 is not sizing its return buffer correctly. - Arnd caught that my recent fix to the size of the pfn_t flags missed updating the flags variable used in the pmem driver. - Toshi found that we mishandle the memremap() return value in devm_memremap(). * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nvdimm: use 'u64' for pfn flags devm_memremap: Fix error value when memremap failed nfit: update address range scrub commands to the acpi 6.1 format libnvdimm, tools/testing/nvdimm: fix 'ars_status' output buffer sizing nfit: fix multi-interface dimm handling, acpi6.1 compatibility |
