Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-5.4

...to receive some reworks to better support nvdimms on powerpc and an
nvdimm security interface update.

There was some last minute build breakage detected in -next so I've
left a patch that finalizes the powerpc compatibility work and some
other fixes out of this pull request.  The build fix requires a new
symbol export that needs an ack from ppc folks, so I'm going to save
that for a post -rc1 update. "libnvdimm/dax: Pick the right alignment
default when creating dax devices" not typically something I would
send during the -rc cycle, but I see no strong reason for it to wait
until v5.5.

The pending fixes for others watching are:

Aneesh Kumar K.V (4):
      libnvdimm/dax: Pick the right alignment default when creating dax devices
      mm/nvdimm: Fix endian conversion issues
      libnvdimm/altmap: Track namespace boundaries in altmap
      libnvdimm/region: Initialize bad block for volatile namespaces

Nathan Chancellor (1):
      libnvdimm/nfit_test: Fix acpi_handle redefinition

  libnvdimm: Use PAGE_SIZE instead of SZ_4K for align check
(2019-09-05 16:11:14 -0700)

----------------------------------------------------------------
libnvdimm for 5.4

- Rework the nvdimm core to accommodate architectures with different page
  sizes and ones that can change supported huge page sizes at boot
  time rather than a compile time constant.

- Introduce a distinct 'frozen' attribute for the nvdimm security state
  since it is independent of the locked state.

- Miscellaneous fixups.

----------------------------------------------------------------
Aneesh Kumar K.V (6):
      libnvdimm/of_pmem: Provide a unique name for bus provider
      libnvdimm/pmem: Advance namespace seed for specific probe errors
      libnvdimm/pfn_dev: Add a build check to make sure we notice when
struct page size change
      libnvdimm/pfn_dev: Add page size and struct page size to pfn superblock
      libnvdimm/label: Remove the dpa align check
      libnvdimm: Use PAGE_SIZE instead of SZ_4K for align check

Btw, minor conflict with your tree due to a fix that went into
v5.3-rc8. Here's my resolution:
