All right, what the hell just happened? A bunch of new material has just been introduced into linux-next. I've partially unpicked the resulting mess, haven't dared trying to compile it yet. To get this far I'll need to drop two patch series and one individual patch: mm-clean-up-is_device__page-definitions.patch mm-introduce-arch_has_pte_devmap.patch arm64-mm-implement-pte_devmap-support.patch arm64-mm-implement-pte_devmap-support-fix.patch mm-sparsemem-introduce-struct-mem_section_usage.patch mm-sparsemem-introduce-a-section_is_early-flag.patch mm-sparsemem-add-helpers-track-active-portions-of-a-section-at-boot.patch mm-hotplug-prepare-shrink_zone-pgdat_span-for-sub-section-removal.patch mm-sparsemem-convert-kmalloc_section_memmap-to-populate_section_memmap.patch mm-hotplug-kill-is_dev_zone-usage-in-__remove_pages.patch mm-kill-is_dev_zone-helper.patch mm-sparsemem-prepare-for-sub-section-ranges.patch mm-sparsemem-support-sub-section-hotplug.patch mm-document-zone_device-memory-model-implications.patch mm-document-zone_device-memory-model-implications-fix.patch mm-devm_memremap_pages-enable-sub-section-remap.patch libnvdimm-pfn-fix-fsdax-mode-namespace-info-block-zero-fields.patch libnvdimm-pfn-stop-padding-pmem-namespaces-to-section-alignment.patch mm-sparsemem-cleanup-section-number-data-types.patch mm-sparsemem-cleanup-section-number-data-types-fix.patch I thought you were just going to move material out of -mm and into hmm.git. Didn't begin to suspect that new and quite disruptive material would be introduced late in -rc7!!
