Dan Williams	c5ed926864	libnvdimm, dax: autodetect support ... For autodetecting a previously established dax configuration we need the info block to indicate block-device vs device-dax mode, and we need to have the default namespace probe hand-off the configuration to the dax_pmem driver.

Dan Williams	cd03412a51	libnvdimm, dax: introduce device-dax infrastructure ... Device DAX is the device-centric analogue of Filesystem DAX (CONFIG_FS_DAX). It allows persistent memory ranges to be allocated and mapped without need of an intervening file system. This initial infrastructure arranges for a libnvdimm pfn-device to be represented as a different device-type so that it can be attached to a driver other than the pmem driver.
