      Pull DAX locking updates from Ross Zwisler:
       "Filesystem DAX locking for 4.7
      
         - We use a bit in an exceptional radix tree entry as a lock bit and
           use it similarly to how page lock is used for normal faults.  This
           fixes races between hole instantiation and read faults of the same
           index.
      
         - Filesystem DAX PMD faults are disabled, and will be re-enabled when
           PMD locking is implemented"

      Pull misc DAX updates from Vishal Verma:
       "DAX error handling for 4.7
      
         - Until now, dax has been disabled if media errors were found on any
           device.  This enables the use of DAX in the presence of these
           errors by making all sector-aligned zeroing go through the driver.
      
         - The driver (already) has the ability to clear errors on writes that
           are sent through the block layer using 'DSMs' defined in ACPI 6.1.
      
        Other misc changes:
      
         - When mounting DAX filesystems, check to make sure the partition is
           page aligned.  This is a requirement for DAX, and previously, we
           allowed such unaligned mounts to succeed, but subsequent
           reads/writes would fail.
      
         - Misc/cleanup fixes from Jan that remove unused code from DAX
           related to zeroing, writeback, and some size checks"
      
      * tag 'dax-misc-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:
        dax: fix a comment in dax_zero_page_range and dax_truncate_page
        dax: for truncate/hole-punch, do zeroing through the driver if possible
        dax: export a low-level __dax_zero_page_range helper
        dax: use sb_issue_zerout instead of calling dax_clear_sectors
        dax: enable dax in the presence of known media errors (badblocks)
        dax: fallback from pmd to pte on error
