Merge tag 'libnvdimm-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "The update for this cycle includes the deprecation of block-aperture
  mode and a new perf events interface for the papr_scm nvdimm driver.

  The perf events approach was acked by PeterZ.

   - Add perf support for nvdimm events, initially only for 'papr_scm'
     devices.

   - Deprecate the 'block aperture' support in libnvdimm, it only ever
     existed in the specification, not in shipping product"
