[PATCH v4 0/6] mm / virtio-mem: support ZONE_MOVABLE
...-mem optimizations, allowing more memory to get reliably unplugged.
Cleanup has_unmovable_pages() and set_migratetype_isolate(), providing
better documentation of how ZONE_MOVABLE interacts with different kind of
unmovable pages (memory offlining vs. alloc_contig_range()).
v3 -> v4:
- "mm/page_isolation: drop WARN_ON_ONCE() in set_migratetype_isolate()"
-- Fix typo in description
- "virtio-mem: don't special-case ZONE_MOVABLE"
-- Add more details why we initialli special-cased ZONE_MOVABLE (via MST)
- "mm: document semantics of ZONE_MOVABLE"
-- Rephrase some parts...
