Pull libnvdimm updates from Dan Williams: "A feature (papr_scm health retrieval) and a fix (sysfs attribute visibility) for v5.8. Vaibhav explains in the merge commit below why missing v5.8 would be painful and I agreed to try a -rc2 pull because only cosmetics kept this out of -rc1 and his initial versions were posted in more than enough time for v5.8 consideration: 'These patches are tied to specific features that were committed to customers in upcoming distros releases (RHEL and SLES) whose time-lines are tied to 5.8 kernel release. Being able to track the health of an nvdimm is critical for our customers that are running workloads leveraging papr-scm nvdimms. Missing the 5.8 kernel would mean missing the distro timelines and shifting forward the availability of this feature in distro kernels by at least 6 months' Summary: - Fix the visibility of the region 'align' attribute. The new unit tests for region alignment handling caught a corner case where the alignment cannot be specified if the region is converted from static to dynamic provisioning at runtime. - Add support for device health retrieval for the persistent memory supported by the papr_scm driver. This includes both the standard sysfs "health flags" that the nfit persistent memory driver publishes and a mechanism for the ndctl tool to retrieve a health-command payload" * tag 'libnvdimm-for-5.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nvdimm/region: always show the 'align' attribute powerpc/papr_scm: Implement support for PAPR_PDSM_HEALTH ndctl/papr_scm,uapi: Add support for PAPR nvdimm specific methods powerpc/papr_scm: Improve error logging and handling papr_scm_ndctl() powerpc/papr_scm: Fetch nvdimm health information from PHYP seq_buf: Export seq_buf_printf powerpc: Document details on H_SCM_HEALTH hcall
