    Linus Torvalds authored
    Pull libnvdimm updates from Ross Zwisler:
     - Require struct page by default for filesystem DAX to remove a number
       of surprising failure cases. This includes failures with direct I/O,
       gdb and fork(2).
     - Add support for the new Platform Capabilities Structure added to the
       NFIT in ACPI 6.2a. This new table tells us whether the platform
       supports flushing of CPU and memory controller caches on unexpected
       power loss events.
     - Revamp vmem_altmap and dev_pagemap handling to clean up code and
       better support future future PCI P2P uses.
     - Deprecate the ND_IOCTL_SMART_THRESHOLD command whose payload has
       become out-of-sync with recent versions of the NVDIMM_FAMILY_INTEL
       spec, and instead rely on the generic ND_CMD_CALL approach used by
       the two other IOCTL families, NVDIMM_FAMILY_{HPE,MSFT}.
     - Enhance nfit_test so we can test some of the new things added in
       version 1.6 of the DSM specification. This includes testing firmware
       download and simulating the Last Shutdown State (LSS) status.
