[GIT PULL] libnvdimm for 4.20

[Williams, Dan J]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-4.20

...to receive the libnvdimm updates for this cycle. No interactions
with other trees this time around. There are updates to the core to
improve driver initialization time, and updates to the 'nfit' driver
for fixing ARS corner cases and exposing some more hardware attributes
to userspace. It has all been in -next for a few releases now with no
reported issues.

  acpi, nfit: Further restrict userspace ARS start requests (2018-10-17 14:02:32 -0700)

----------------------------------------------------------------
libnvdimm for 4.20

+ACo- Improve the efficiency and performance of reading nvdimm-namespace
  labels. Reduce the amount of label data read at driver load time by a
  few orders of magnitude. Reduce heavyweight call-outs to
  platform-firmware routines.

+ACo- Handle media errors located in the 'struct page' array stored on a
  persistent memory namespace. Let the kernel clear these errors rather
  than an awkward userspace workaround.

+ACo- Fix Address Range Scrub (ARS) completion tracking. Correct occasions
  where the kernel indicates completion of ARS before submission.

+ACo- Fix asynchronous device registration reference counting.

+ACo- Add support for reporting an nvdimm dirty-shutdown-count via sysfs.

+ACo- Fix various small libnvdimm core and uapi issues.
