This series adds support for OpenCAPI Persistent Memory devices, exposing
them as nvdimms so that we can make use of the existing infrastructure.

Alastair D'Silva (27):
  powerpc: Add OPAL calls for LPC memory alloc/release
  mm/memory_hotplug: Allow check_hotplug_memory_addressable to be called
    from drivers
  powerpc: Map & release OpenCAPI LPC memory
  ocxl: Remove unnecessary externs
  ocxl: Address kernel doc errors & warnings
  ocxl: Tally up the LPC memory on a link & allow it to be mapped
  ocxl: Add functions to map/unmap LPC memory
  ocxl: Emit a log message showing how much LPC memory was detected
  ocxl: Save the device serial number in ocxl_fn
  powerpc: Add driver for OpenCAPI Persistent Memory
  powerpc: Enable the OpenCAPI Persistent Memory driver for
    powernv_defconfig
  powerpc/powernv/pmem: Add register addresses & status values to the
    header
  powerpc/powernv/pmem: Read the capability registers & wait for device
    ready
  powerpc/powernv/pmem: Add support for Admin commands
  powerpc/powernv/pmem: Add support for near storage commands
  powerpc/powernv/pmem: Register a character device for userspace to
    interact with
  powerpc/powernv/pmem: Implement the Read Error Log command
  powerpc/powernv/pmem: Add controller dump IOCTLs
  powerpc/powernv/pmem: Add an IOCTL to report controller statistics
  powerpc/powernv/pmem: Forward events to userspace
  powerpc/powernv/pmem: Add an IOCTL to request controller health & perf
    data
  powerpc/powernv/pmem: Implement the heartbeat command
  powerpc/powernv/pmem: Add debug IOCTLs
  powerpc/powernv/pmem: Expose SMART data via ndctl
  powerpc/powernv/pmem: Expose the serial number in sysfs
  powerpc/powernv/pmem: Expose the firmware version in sysfs
  MAINTAINERS: Add myself & nvdimm/ocxl to ocxl
