powerpc/papr_scm: Move duplicate definitions to common header files papr_scm and ndtest share common PDSM payload structs like nd_papr_pdsm_health. Presently these structs are duplicated across papr_pdsm.h and ndtest.h header files. Since 'ndtest' is essentially arch independent and can run on platforms other than PPC64, a way needs to be deviced to avoid redundancy and duplication of PDSM structs in future. So the patch proposes moving the PDSM header from arch/powerpc/include- -/uapi/ to the generic include/uapi/linux directory. Also, there are some #defines common between papr_scm and ndtest which are not exported to the user space. So, move them to a header file which can be shared across ndtest and papr_scm via newly introduced include/linux/papr_scm.h.

ndtest: Add regions and mappings to the test buses The bus config array is used to hold the regions and the respective mappings. This config based interface enables to change the dimm/region/namespace layouts easily.

ndtest: Add dimms to the two buses A config array is used to hold the dimms for each bus. These dimms are registered with nvdimm, and new nvdimms are created on the buses.

testing/nvdimm: Add test module for non-nfit platforms The current test module cannot be used for testing platforms (make check) that do not have support for NFIT. In order to get the ndctl tests working, we need a module which can emulate NVDIMM devices without relying on ACPI/NFIT. The aim of this proposed module is to implement a similar functionality to the existing module but without the ACPI dependencies. This RFC series is split into reviewable and compilable chunks. This patch adds a new driver and registers two nvdimm bus needed for ndctl make check.
