Hi Dan, Jérôme and Jason,
below is a series that cleans up the dev_pagemap interface so that it is more easily usable, which removes the need to wrap it in hmm and thus allowing to kill a lot of code
Note: this series is on top of Linux 5.2-rc6 and has some minor conflicts with the hmm tree that are easy to resolve.

Changes since v3: - pull in "mm/swap: Fix release_pages() when releasing devmap pages" and rebase the other patches on top of that - fold the hmm_devmem_add_resource into the DEVICE_PUBLIC memory removal patch - remove _vm_normal_page as it isn't needed without DEVICE_PUBLIC memory - pick up various ACKs
Changes since v2: - fix nvdimm kunit build - add a new memory type for device dax - fix a few issues in intermediate patches that didn't show up in the end result - incorporate feedback from Michal Hocko, including killing of the DEVICE_PUBLIC memory type entirely
Changes since v1: - rebase - also switch p2pdma to the internal refcount - add type checking for pgmap->type - rename the migrate method to migrate_to_ram - cleanup the altmap_valid flag - various tidbits from the reviews
