Hi Linus, please pull from: +AKA- git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-4.8 ...to receive the libnvdimm update for 4.8. This has been in -next with the following reported conflicts: 1/ The +AF8AXw-pmem address space has been removed. +AKA-New usages of +AF8AXw-pmem came in through the DM tree this cycle. 2/ A minor conflict in the pmem driver with the device+AF8-add+AF8-disk() changes that came in through the block layer. 3/ The removal of pcommit collided with new enabling in KVM. +AKA-At the time of writing you have not yet merged the KVM tree.

Instead, the requirement is that platforms implement either +AKAAoACg-ADR, or provide one or more flush addresses per nvdimm. ADR +AKAAoACg-(Asynchronous DRAM Refresh) flushes data in posted write buffers to the +AKAAoACg-memory controller on a power-fail event. Flush addresses are defined in +AKAAoACg-ACPI 6.x as an NVDIMM Firmware Interface Table (NFIT) sub-structure: +AKAAoACgACI-Flush Hint Address Structure+ACI-. A flush hint is an mmio address that +AKAAoACg-when written and fenced assures that all previous posted writes +AKAAoACg-targeting a given dimm have been flushed to media. 2/ On-demand ARS (address range scrub): +AKAAoACg-Linux uses the results of the ACPI ARS commands to track bad blocks +AKAAoACg-in pmem devices.+AKAAoA-When latent errors are detected we re-scrub the media +AKAAoACg-to refresh the bad block list, userspace can also request a re-scrub at +AKAAoACg-any time. 3/ Support for the Microsoft DSM (device specific method) command format. 4/ Support for EDK2/OVMF virtual disk device memory ranges. 5/ Various fixes and cleanups across the subsystem. ---------------------------------------------------------------- Dan Williams (32): +AKAAoACgAKAAoACg-libnvdimm: use devm+AF8-add+AF8-action+AF8-or+AF8-reset() +AKAAoACgAKAAoACg-libnvdimm: IS+AF8-ERR() usage cleanup +AKAAoACgAKAAoACg-tools/testing/nvdimm: add pfn device dependency +AKAAoACgAKAAoACg-libnvdimm, pmem: allow nfit+AF8-test to override pmem+AF8-direct+AF8-access() +AKAAoACgAKAAoACg-tools/testing/nvdimm: replace CONFIG+AF8-DMA+AF8-CMA dependency with vmalloc() +AKAAoACgAKAAoACg-tools/testing/nvdimm: remove +AF8AXw-wrap+AF8-devm+AF8-memremap+AF8-pages placeholder +AKAAoACgAKAAoACg-nfit: always associate flush hints +AKAAoACgAKAAoACg-nfit: don't override return value of nfit+AF8-mem+AF8-init +AKAAoACgAKAAoACg-libnvdimm: introduce devm+AF8-nvdimm+AF8-memremap(), convert nfit+AF8-spa+AF8-map() users +AKAAoACgAKAAoACg-libnvdimm, nfit: remove nfit+AF8-spa+AF8-map() infrastructure +AKAAoACgAKAAoACg-libnvdimm, nfit: move flush hint mapping to region-device driver-data +AKAAoACgAKAAoACg-tools/testing/nvdimm: simulate multiple flush hints per-dimm +AKAAoACgAKAAoACg-libnvdimm: keep region data alive over namespace removal +AKAAoACgAKAAoACg-libnvdimm: introduce nvdimm+AF8-flush() and nvdimm+AF8-has+AF8-flush() +AKAAoACgAKAAoACg-libnvdimm: cycle flush hints +AKAAoACgAKAAoACg-libnvdimm, pmem: use REQ+AF8-FUA, REQ+AF8-FLUSH for nvdimm+AF8-flush() +AKAAoACgAKAAoACg-libnvdimm, pmem: flush posted-write queues on shutdown +AKAAoACgAKAAoACg-fs/dax: remove wmb+AF8-pmem() +AKAAoACgAKAAoACg-libnvdimm, pmem: use nvdimm+AF8-flush() for namespace I/O writes +AKAAoACgAKAAoACg-pmem: kill wmb+AF8-pmem() +AKAAoACgAKAAoACg-pmem: kill +AF8AXw-pmem address space +AKAAoACgAKAAoACg-tools/testing/nvdimm: add virtual ramdisk range +AKAAoACgAKAAoACg-tools/testing/nvdimm: add manufacturing+AF8Aew-date+AHw-location+AH0- dimm properties +AKAAoACgAKAAoACg-nfit: fix +AF8-FIT evaluation memory leak +- use after free +AKAAoACgAKAAoACg-nfit: cleanup acpi+AF8-nfit+AF8-init calling convention +AKAAoACgAKAAoACg-libnvdimm: move -+AD4-module to struct nvdimm+AF8-bus+AF8-descriptor +AKAAoACgAKAAoACg-nfit, tools/testing/nvdimm/: unify shutdown paths +AKAAoACgAKAAoACg-Revert +ACI-KVM: x86: add pcommit support+ACI- +AKAAoACgAKAAoACg-x86/insn: remove pcommit +AKAAoACgAKAAoACg-libnvdimm: register nvdimm+AF8-bus devices with an nd+AF8-bus driver +AKAAoACgAKAAoACg-nfit: move to nfit/ sub-directory +AKAAoACgAKAAoACg-Merge branch 'for-4.8/libnvdimm' into libnvdimm-for-next Johannes Thumshirn (1): +AKAAoACgAKAAoACg-libnvdimm: initialize struct blk+AF8-integrity with 0 Lee, Chun-Yi (1): +AKAAoACgAKAAoACg-acpi, nfit: treat virtual ramdisk SPA as pmem region Markus Elfring (1): +AKAAoACgAKAAoACg-libnvdimm-btt: Delete an unnecessary check before the function call +ACIAXwBf-nd+AF8-device+AF8-register+ACI- Sajjan, Vikas C (2): +AKAAoACgAKAAoACg-nfit: use devm+AF8-add+AF8-action+AF8-or+AF8-reset() +AKAAoACgAKAAoACg-dax: use devm+AF8-add+AF8-action+AF8-or+AF8-reset() Vishal Verma (4): +AKAAoACgAKAAoACg-libnvdimm, btt: update the usage section in Documentation +AKAAoACgAKAAoACg-pmem: clarify a debug print in pmem+AF8-clear+AF8-poison +AKAAoACgAKAAoACg-nfit, libnvdimm: allow an ARS scrub to be triggered on demand +AKAAoACgAKAAoACg-nfit: do an ARS scrub on hitting a latent media error stuart hayes (1): +AKAAoACgAKAAoACg-nfit: add Microsoft NVDIMM DSM command set to white list +AKA-Documentation/filesystems/Locking+AKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAHwAoACgAKA-2 +-- +AKA-Documentation/nvdimm/btt.txt+AKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoAB8AKAAoA-28 +-- +AKA-arch/powerpc/sysdev/axonram.c+AKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAfACgAKAAoA-4 +-- +AKA-arch/x86/include/asm/cpufeatures.h+AKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoAB8AKAAoACg-1 -
