Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-5.18

...to receive the libnvdimm update for this cycle which 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. You will notice the top commit is less than a week old as
linux-next exposure identified some build failure scenarios. Kajol
turned around a fix and it has appeared in linux-next with no
additional reports. Some other fixups for the removal of
block-aperture mode also generated some follow-on fixes from -next
exposure.

I am not aware of anything else outstanding, please pull.

  nvdimm/blk: Fix title level (2022-03-23 17:52:33 -0700)

----------------------------------------------------------------
libnvdimm for 5.18

- 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.
