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.
