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" * tag 'libnvdimm-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nvdimm/blk: Fix title level MAINTAINERS: remove section LIBNVDIMM BLK: MMIO-APERTURE DRIVER powerpc/papr_scm: Fix build failure when drivers/nvdimm: Fix build failure when CONFIG_PERF_EVENTS is not set nvdimm/region: Delete nd_blk_region infrastructure ACPI: NFIT: Remove block aperture support nvdimm/namespace: Delete nd_namespace_blk nvdimm/namespace: Delete blk namespace consideration in shared paths nvdimm/blk: Delete the block-aperture window driver nvdimm/region: Fix default alignment for small regions docs: ABI: sysfs-bus-nvdimm: Document sysfs event format entries for nvdimm pmu powerpc/papr_scm: Add perf interface support drivers/nvdimm: Add perf interface to expose nvdimm performance stats drivers/nvdimm: Add nvdimm pmu structure
