Changes since v2 [1]: * rebase on -next to integrate with commit 273752c9ff03 "dm, dax: Make sure dm_dax_flush() is called if device supports it" (kbuild robot) * fix CONFIG_DAX dependencies to upgrade CONFIG_DAX=m to CONFIG_DAX=y (kbuild robot)

Bart points out that the DAX core is unconditionally enabled if device-mapper is enabled. Add some config machinery and some stub-static-inline routines to allow dax infrastructure to be deleted from device-mapper at compile time.
Since this depends on commit 273752c9ff03 that's already in -next, this should go through the device-mapper tree. ---
