["Williams, Dan J" <dan.j.williams@intel.com>]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-4.14

...to receive:

A rework of media error handling in the BTT driver and other updates.
It has appeared in a few -next releases and collected some late-
breaking build-error and warning fixups as a result. There are no known
merge conflicts, and the touches to fs/ have reviewed-by tags.

  libnvdimm, btt: fix format string warnings (2017-09-09 11:31:39 -0700)

----------------------------------------------------------------
libnvdimm for 4.14

* Media error handling support in the Block Translation Table (BTT)
  driver is reworked to address sleeping-while-atomic locking and
  memory-allocation-context conflicts.

* The dax_device lookup overhead for xfs and ext4 is moved out of the
  iomap hot-path to a mount-time lookup.

* A new 'ecc_unit_size' sysfs attribute is added to advertise the
  read-modify-write boundary property of a persistent memory range.

* Preparatory fix-ups for arm and powerpc pmem support are included
  along with other miscellaneous fixes.
