Linus Torvalds 3be134e515 libnvdimm for 4.10 
* Dynamic label support: To date namespace label support has been
 limited to disambiguating cases where PMEM (direct load/store) and BLK
 (mmio aperture) accessed-capacity alias on the same DIMM. Since 4.9 added
 support for multiple namespaces per PMEM-region there is value to
 support namespace labels even in the non-aliasing case. The presence of
 a valid namespace index block force-enables label support when the
 kernel would otherwise rely on region boundaries, and permits the region
 to be sub-divided.
 
 * Handle media errors in namespace metadata: Complement the error
 handling for media errors in namespace data areas with support for
 clearing errors on writes, and downgrading potential machine-check
 exceptions to simple i/o errors on read.
 
 * Device-DAX region attributes: Add 'align', 'id', and 'size' as
 attributes for device-dax regions. In particular this enables userspace
 tooling to generically size memory mapping and i/o operations. Prevent
 userspace from growing assumptions / dependencies about the parent
 device topology for a dax region. A libnvdimm namespace may not always
 be the parent device of a dax region.
 
 * Various cleanups and small fixes.

Merge tag 'libnvdimm-for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "The libnvdimm pull request is relatively small this time around due to
  some development topics being deferred to 4.11.

  As for this pull request the bulk of it has been in -next for several
  releases leading to one late fix being added (commit 868f036fee
  ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It
  has received a build success notification from the 0day-kbuild robot
  and passes the latest libnvdimm unit tests.

  Summary:

   - Dynamic label support: To date namespace label support has been
     limited to disambiguating cases where PMEM (direct load/store) and
     BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since
     4.9 added support for multiple namespaces per PMEM-region there is
     value to support namespace labels even in the non-aliasing case.
     The presence of a valid namespace index block force-enables label
     support when the kernel would otherwise rely on region boundaries,
     and permits the region to be sub-divided.

   - Handle media errors in namespace metadata: Complement the error
     handling for media errors in namespace data areas with support for
     clearing errors on writes, and downgrading potential machine-check
     exceptions to simple i/o errors on read.

   - Device-DAX region attributes: Add 'align', 'id', and 'size' as
     attributes for device-dax regions. In particular this enables
     userspace tooling to generically size memory mapping and i/o
     operations. Prevent userspace from growing assumptions /
     dependencies about the parent device topology for a dax region. A
     libnvdimm namespace may not always be the parent device of a dax
     region.

   - Various cleanups and small fixes"
