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.
