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

Implement support for fetching nvdimm health information via
H_SCM_HEALTH hcall as documented in Ref[1]. The hcall returns a pair
of 64-bit bitmap, bitwise-and of which is then stored in
'struct papr_scm_priv' and subsequently partially exposed to
user-space via newly introduced dimm specific attribute
'papr/flags'. Since the hcall is costly, the health information is
cached and only re-queried, 60s after the previous successful hcall.

The patch also adds a  documentation text describing flags reported by
the the new sysfs attribute 'papr/flags' is also introduced at
Documentation/ABI/testing/sysfs-bus-papr-pmem.

[1] commit 58b278f568f0 ("powerpc: Provide initial documentation for
PAPR hcalls")
