The new FUSE file system requires some DAX changes.
* dax/fsdev: fix uninitialized kaddr in fsdev_dax_zero_page_range()
* dax: export dax_dev_get()
* dax: Add fs_dax_get() func to prepare dax for fs-dax usage
* dax: Add dax_set_ops() for setting dax_operations at bind time
* dax: Add dax_operations for use by fs-dax on fsdev dax
* dax: Save the kva from memremap
* dax: add fsdev.c driver for fs-dax on character dax
* dax: Factor out dax_folio_reset_order() helper
* dax: move dax_pgoff_to_phys from [drivers/dax/] device.c to bus.c

Pull dax updates from Ira Weiny:
"The series adds DAX support required for the upcoming fuse/famfs file
system.[1] The support here is required because famfs is backed by
devdax rather than pmem. This all lays the groundwork for using shared
memory as a file system"
