From: Alastair D'Silva <alastair@d-silva.org>

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

The first patch (in memory_hotplug) has reviews/acks, but has
not yet made it upstream.

Alastair D'Silva (10):
  memory_hotplug: Add a bounds check to __add_pages
  nvdimm: remove prototypes for nonexistent functions
  powerpc: Add OPAL calls for LPC memory alloc/release
  powerpc: Map & release OpenCAPI LPC memory
  ocxl: Tally up the LPC memory on a link & allow it to be mapped
  ocxl: Add functions to map/unmap LPC memory
  ocxl: Save the device serial number in ocxl_fn
  nvdimm: Add driver for OpenCAPI Storage Class Memory
  powerpc: Enable OpenCAPI Storage Class Memory driver on bare metal
  ocxl: Conditionally bind SCM devices to the generic OCXL driver
