A new sub-system in support of non-volatile memory storage devices. See
"[PATCH v6 21/21] libnvdimm: Non-Volatile Devices" for an overview.

Changes since v5 [1]:

1/ Add rationale/justification to the changelog for "[PATCH v6 20/21]
tools/testing/nvdimm: libnvdimm unit test infrastructure". Explain
why QEMU is not suitable. (Christoph)

2/ Expand the changelog of "[PATCH v6 18/21] nd_btt: atomic sector
updates" to give the reasoning behind architecture decisions related
to scaling. (Christoph)

3/ Introduce ->rw_bytes() to struct block_device_operations and kill off
the "ndio" implementation (save a couple hundred lines of glue code).
(Christoph)

4/ Kill usage of __iomem in the namespace label implementation in favor
of properly using byte-order helpers. (Christoph)

5/ Kill the include path munging in "[PATCH v6 20/21]
tools/testing/nvdimm: libnvdimm unit test infrastructure" this makes
the unit test implementation have near zero impact on the libnvdimm
code base. (Christoph)

6/ Miscellaneous 80 column fixups. (Christoph)

7/ Restore BLK_DEV and PHYS_ADDR_T_64BIT dependencies to LIBNVDIMM.
