A new sub-system in support of non-volatile memory storage devices.

Stephen, please add libnvdimm-for-next to -next:

  git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm libnvdimm-for-next

Changes since v6 [1]:

1/ Deferred the patches dependent on ->rw_bytes() (BTT - stacked block
   driver, BLK - mmio aperture windows driver, NFIT_TEST - unit test
   infrastructure for all libnvdimm + nfit components) to their own
   patchset. Make the ->rw_bytes() implementation the first patch in
   that series (Christoph)

2/ Collected acks from Christoph and Rafael!

3/ Add a HAS_IOMEM dependency to CONFIG_BLK_DEV_PMEM following commit
   b6f2098fb708 "block: pmem: Add dependency on HAS_IOMEM" in 4.1-rc8.

4/ Move libnvdimm to subsys_initcall() and move arch/x86/kernel/pmem.c
   back to device_initcall().  This allows ACPI_NFIT to be built-in.
   (Linda)

5/ Drop the ACPI_DRIVER_ALL_NOTIFY_EVENTS flag in the nfit driver.
   (Rafael)

6/ Reference count the nvdimm_drvdata object.  This fixes a bug that was
   found when the unit tests were extended to test disabling an nvdimm
   while a region device still had references to label data.

Dan Williams (16):
      e820, efi: add ACPI 6.0 persistent memory types
      libnvdimm, nfit: initial libnvdimm infrastructure and NFIT support
      libnvdimm: control character device and nvdimm_bus sysfs attributes
      libnvdimm, nfit: dimm/memory-devices
      libnvdimm: control (ioctl) messages for nvdimm_bus and nvdimm devices
      libnvdimm, nvdimm: dimm driver and base libnvdimm device-driver infrastructure
      libnvdimm, nfit: regions (block-data-window, persistent memory, volatile memory)
      libnvdimm: support for legacy (non-aliasing) nvdimms
      libnvdimm, pmem: move pmem to drivers/nvdimm/
      libnvdimm, pmem: add libnvdimm support to the pmem driver
      libnvdimm, nfit: add interleave-set state-tracking infrastructure
      libnvdimm: namespace indices: read and validate
      libnvdimm: pmem label sets and namespace instantiation.
      libnvdimm: blk labels and namespace instantiation
      libnvdimm: write pmem label set
      libnvdimm: write blk label set

We have been successfully running this patchset on our NFIT-enabled
prototype systems with pmem.  (Intel example _DSM, label, blk are not
available for testing.)

So for patch 1/16 to 4/15, and 6/16 to 10/16.
