Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm libnvdimm-fixes
...to receive a single patch removing some structure definitions from a uapi header file. These payloads are never processed directly by the kernel they are simply passed through an ioctl as opaque blobs to the ACPI _DSM (Device Specific Method) interface.
Userspace should not be depending on the kernel to define these payloads. We will instead provide these definitions via the existing libndctl (https://github.com/pmem/ndctl) project that has NVDIMM command helpers and other definitions.

commit 7a14724f54bf9889fcb1a9f1d4aa4e1d2e969d93 Author: Dan Williams <dan.j.williams@intel.com> Date: Mon Aug 28 08:33:20 2017 -0700
libnvdimm: clean up command definitions Remove the command payloads that do not have an associated libnvdimm ioctl. I.e. remove the payloads that would only ever be carried in the ND_CMD_CALL envelope. This prevents userspace from growing unnecessary dependencies on this kernel header when userspace already has everything it needs to craft and send these commands.
