libnvdimm: move poison list functions to a new 'badrange' file
nfit_test needs to use the poison list manipulation code as well. Make it more generic and in the process rename poison to badrange, and move all the related helpers to a new file. Signed-off-by: Dave Jiang <dave.jiang@intel.com> [vishal: Add badrange.o to nfit_test's Kbuild] [vishal: add a missed include in bus.c for the new badrange functions] [vishal: rename all instances of 'be' to 'bre'] Signed-off-by: Vishal Verma <vishal.l.verma@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
