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.


The following changes since commit 14ccee78fc82f5512908f4424f541549a5705b89:

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

libnvdimm for 4.14

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

+ACo- The dax+AF8-device lookup overhead for xfs and ext4 is moved out of the
iomap hot-path to a mount-time lookup.

+ACo- A new 'ecc+AF8-unit+AF8-size' sysfs attribute is added to advertise the
read-modify-write boundary property of a persistent memory range.

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