Subject: [GIT PULL] libnvdimm fixes for 4.20-rc3

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-fixes-4.20-rc3

...to receive a small batch of fixes for v4.20-rc3.

These have soaked in -next for a few releases. The overflow
continuation fix addresses something that has been broken for several
releases. Arguably it could wait even longer, but it's a one line fix
and this finishes the last of the known address range scrub bug
reports. The revert addresses a lockdep regression. The unit tests are
not critical to fix, but no reason to hold this fix back.

  Revert "acpi, nfit: Further restrict userspace ARS start requests" (2018-11-10 09:54:28 -0800)

----------------------------------------------------------------
libnvdimm 4.20-rc3

- Address Range Scrub overflow continuation handling has been broken
  since it was initially merged. It was only recently that error injection
  and platform-BIOS support enabled this corner case to be exercised.

- The recent attempt to provide more isolation for the kernel Address
  Range Scrub state machine from userapace initiated sessions triggers a
  lockdep report. Revert and try again at the next merge window.

- Fix a kasan reported buffer overflow in libnvdimm unit test
  infrastrucutre (nfit_test)
