Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dan Williams: - a boot regression (since v4.2) fix for some ARM configurations from Tyler - regression (since v4.1) fixes for mkfs.xfs on a DAX enabled device from Jeff. These are tagged for -stable. - a pair of locking fixes from Axel that are hidden from lockdep since they involve device_lock(). The "btt" one is tagged for -stable, the other only applies to the new "pfn" mechanism in v4.3. - a fix for the pmem ->rw_page() path to use wmb_pmem() from Ross. * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: mm: fix type cast in __pfn_to_phys() pmem: add proper fencing to pmem_rw_page() libnvdimm: pfn_devs: Fix locking in namespace_store libnvdimm: btt_devs: Fix locking in namespace_store blockdev: don't set S_DAX for misaligned partitions dax: fix O_DIRECT I/O to the last block of a blockdev
