Linus Torvalds d080827f85 libnvdimm for 4.5
1/ Media error handling: The 'badblocks' implementation that originated
    in md-raid is up-levelled to a generic capability of a block device.
    This initial implementation is limited to being consulted in the pmem
    block-i/o path.  Later, 'badblocks' will be consulted when creating
    dax mappings.
 
 2/ Raw block device dax: For virtualization and other cases that want
    large contiguous mappings of persistent memory, add the capability to
    dax-mmap a block device directly.
 
 3/ Increased /dev/mem restrictions: Add an option to treat all io-memory
    as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is
    actively using an address range.  This behavior is controlled via the
    new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the
    existing "iomem=relaxed" kernel command line option.
 
 4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
    block device shutdown crash fix, and other small libnvdimm fixes.

Merge tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "The bulk of this has appeared in -next and independently received a
  build success notification from the kbuild robot.  The 'for-4.5/block-
  dax' topic branch was rebased over the weekend to drop the "block
  device end-of-life" rework that Al would like to see re-implemented
  with a notifier, and to address bug reports against the badblocks
  integration.

  There is pending feedback against "libnvdimm: Add a poison list and
  export badblocks" received last week.  Linda identified some localized
  fixups that we will handle incrementally.

  Summary:

   - Media error handling: The 'badblocks' implementation that
     originated in md-raid is up-levelled to a generic capability of a
     block device.  This initial implementation is limited to being
     consulted in the pmem block-i/o path.  Later, 'badblocks' will be
     consulted when creating dax mappings.

   - Raw block device dax: For virtualization and other cases that want
     large contiguous mappings of persistent memory, add the capability
     to dax-mmap a block device directly.

   - Increased /dev/mem restrictions: Add an option to treat all
     io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access
     while a driver is actively using an address range.  This behavior
     is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be
     overridden by the existing "iomem=relaxed" kernel command line
     option.

   - Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
     block device shutdown crash fix, and other small libnvdimm fixes"
